95-548: Besides the branding differences, there are several models of the HTC TyTN: the TyTN 100, the TyTN 200, and the TyTN 300. The TyTN 100 has no front-facing camera or a .1-megapixel front-facing camera; the TyTN 200 has a .1-megapixel front-facing camera; and the TyTN 300 has a .3-megapixel front-facing camera. The TyTN Model was sold as: The TyTN shipped with Windows Mobile 5 AKU 2.3. HTC released AKU3 ROMs to carriers, though it

190-432: A dedicated x64 edition ) has x64 editions. The first version of Windows NT to support ARM64 devices with Qualcomm processors was Windows 10, version 1709 . This is a full version of Windows, rather than the cut-down Windows RT . The minimum hardware specification required to run each release of the professional workstation version of Windows NT has been fairly slow-moving until the 6.0 (Vista) release, which requires

285-513: A taskbar and Start menu ), which originally appeared in Windows 95 . The first release was given version number 3.1 to match the contemporary 16-bit Windows; magazines of that era claimed the number was also used to make that version seem more reliable than a ".0" release. Also the Novell IPX protocol was apparently licensed only to 3.1 versions of Windows software. The NT version number

380-533: A "mobile" version of the Microsoft OneNote program and an interactive "Getting Started" wizard. Domain Enroll is functionality to connect the device to System Center Mobile Device Manager 2008, a product to manage mobile devices. Windows Mobile 6.1 also had improved bandwidth efficiency in its push-email protocol ActiveSync up to 40%; this considerably improved battery life in many devices. Aside from

475-455: A 64-bit kernel and 64-bit memory addressing. Windows NT is a group or family of products — like Windows is a group or family. Windows NT is a sub-grouping of Windows. The first version of Windows NT, 3.1 , was produced for workstation and server computers. It was commercially focused — and intended to complement consumer versions of Windows that were based on MS-DOS (including Windows 1.0 through Windows 3.1x ). In 1996, Windows NT 4.0

570-401: A TCP/IP stack derived at first from a STREAMS -based stack from Spider Systems , then later rewritten in-house). Windows NT 3.1 was the first version of Windows to use 32-bit flat virtual memory addressing on 32-bit processors. Its companion product, Windows 3.1, used segmented addressing and switches from 16-bit to 32-bit addressing in pages. Windows NT 3.1 featured a core kernel providing

665-471: A layered design architecture that consists of two main components, user mode and kernel mode . Programs and subsystems in user mode are limited in terms of what system resources they have access to, while the kernel mode has unrestricted access to the system memory and external devices. Kernel mode in Windows NT has full access to the hardware and system resources of the computer. The Windows NT kernel

760-407: A more integrated manner. Windows NT 24H2 (10.0.26100.2454) (November 21, 2024 ; 2 days ago  ( 2024-11-21 ) ) [±] 23H2 (10.0.22635.4515) (November 22, 2024 ; 1 day ago  ( 2024-11-22 ) ) [±] 24H2 (10.0.26120.2415) (November 22, 2024 ; 1 day ago  ( 2024-11-22 ) ) [±] Windows NT

855-481: A new error reporting facility similar to that present in desktop and server Windows systems. Caller ID now supports photos so a user can apply an image to each contact to show when a call is received. DirectShow was also natively added. This release was the first to include DirectDraw with hardware acceleration, replacing the deprecated graphics component of GAPI . Windows Mobile 5.0 requires at least 64 MB of ROM (it's advisable to have 64 MB of RAM), and

950-656: A portable operating system, compatible with OS/2 and POSIX and supporting multiprocessing , in October 1988. When development started in November 1989, Windows NT was to be known as OS/2 3.0, the third version of the operating system developed jointly by Microsoft and IBM . To ensure portability, initial development was targeted at the Intel i860 XR RISC processor , switching to the MIPS R3000 in late 1989, and then

1045-406: A result, Pocket PC 2000 was released on multiple CPU architectures, such as SH-3 , MIPS , and ARM . The only resolution supported by this release was 240 x 320 ( QVGA ). Removable storage card formats that were supported were CompactFlash and MultiMediaCard . Infrared (IR) File beaming capability was among the original hardware features.

1140-563: A revamped GUI, a new Today screen resembling that of Microsoft's Zune player with vertically scrollable labels (called 'Titanium') in terms of functionality with a styling similar to that of Windows 7 . WM 6.5 also includes the new Internet Explorer Mobile 6 browser, with improved interface. Along with Windows Mobile 6.5, Microsoft announced several cloud computing services codenamed "SkyBox", "SkyLine", "SkyMarket". "SkyBox" has been confirmed as My Phone , while "SkyMarket" has been confirmed as Windows Marketplace for Mobile . This version

1235-520: A revision of Windows NT, even though the Windows NT name itself has not been used in many other Windows releases since Windows NT 4.0 in 1996. Windows NT provides many more features than other Windows releases, among them being support for multiprocessing , multi-user systems , a "pure" 32-bit kernel with 32-bit memory addressing, support for instruction sets other than x86 , and many other system services such as Active Directory and more. Newer versions of Windows NT support 64-bit computing , with

1330-475: A stripped-down version of the Windows operating system. Windows 11 is the first non-server version of Windows NT that does not support 32-bit platforms. The 64-bit versions of Windows NT were originally intended to run on Itanium and DEC Alpha ; the latter was used internally at Microsoft during early development of 64-bit Windows. This continued for some time after Microsoft publicly announced that it

1425-444: A system API, running in supervisor mode (ring 0 in x86; referred to in Windows NT as "kernel mode" on all platforms), and a set of user-space environments with their own APIs which included the new Win32 environment, an OS/2 1.3 text-mode environment and a POSIX environment. The full preemptive multitasking kernel could interrupt running tasks to schedule other tasks, without relying on user programs to voluntarily give up control of

1520-555: A very small amount written in assembly language . C is mostly used for the kernel code while C++ is mostly used for user-mode code. Assembly language is avoided where possible because it would impede portability . The following are the releases of Windows based on the Windows NT technology. Windows NT 3.1 to 3.51 incorporated the Program Manager and File Manager from the Windows 3.1x series. Windows NT 4.0 onwards replaced those programs with Windows Explorer (including

1615-599: Is cold-booted . Further updates both, security and feature, can now also be provided using Operating System Live Update. Among other improvements: 320×320 and 800×480 (WVGA) screen resolution support (The S01SH or "Em One" by Sharp was the first and only device to have an 800×480 screen on WM5), Improved Remote Desktop access (available for only certain Pocket PCs), Customer Feedback option, Smartfilter for searching within programs and Unlicensed Mobile Access (UMA) support for select operators. Windows Mobile 6.1

1710-525: Is a hybrid kernel ; the architecture comprises a simple kernel , hardware abstraction layer (HAL), drivers, and a range of services (collectively named Executive ), which all exist in kernel mode. The booting process of Windows NT begins with NTLDR in versions before Vista and the Windows Boot Manager in Vista and later. The boot loader is responsible for accessing the file system on

1805-473: Is a proprietary graphical operating system produced by Microsoft as part of its Windows product line, the first version of which, Windows NT 3.1 , was released on July 27, 1993. Originally made for the workstation , office, and server markets, the Windows NT line was made available to consumers with the release of Windows XP in 2001. The underlying technology of Windows NT continues to exist to this day with incremental changes and improvements, with

1900-402: Is a discontinued mobile operating system developed by Microsoft for smartphones and personal digital assistants (PDA). Designed to be the portable equivalent of the Windows desktop OS in the emerging mobile/portable area, the operating system is built on top of Windows CE (later known as Windows Embedded Compact) and was originally released as Pocket PC 2000 . Microsoft introduced

1995-463: Is achieved on IA-32 via an integrated DOS Virtual Machine – although this feature is not available on other architectures. NT has supported per-object (file, function, and role) access control lists allowing a rich set of security permissions to be applied to systems and services. NT has also supported Windows network protocols, inheriting the previous OS/2 LAN Manager networking, as well as TCP/IP networking (for which Microsoft used to implement

2090-466: Is not now generally used for marketing purposes, but is still used internally, and said to reflect the degree of changes to the core of the operating system. However, for application compatibility reasons, Microsoft kept the major version number as 6 in releases following Vista, but changed it later to 10 in Windows 10. The build number is an internal identifier used by Microsoft's developers and beta testers. Starting with Windows 8.1 , Microsoft changed

2185-626: Is now preinstalled with the OS. Developers and users also have access to Microsoft SQL Server 2005 Compact Edition for storage and retrieval of information. AJAX , JavaScript , and XMLDOM support were added to Internet Explorer Mobile along with improved devicewide Internet Sharing. Communication abilities were further enhanced with a new Microsoft Bluetooth Stack and VoIP (Internet calling) support with acoustic echo cancellation and MSRT audio codec. To improve security Microsoft added Storage Card Encryption so that encryption keys are lost if device

2280-599: Is powered by Windows CE 5.0 (version 5.2) and is strongly linked to the then newly introduced Windows Live and Exchange 2007 products. Windows Mobile 6 Standard was first offered on the Orange's SPV E650 , while Windows Mobile 6 Professional was first offered on the O2's Xda Terra. Aesthetically, Windows Mobile 6 was meant to be similar in design to the then newly released Windows Vista . Functionally, it works much like Windows Mobile 5, but with much better stability. Along with

2375-849: Is presented as an enterprise handheld device, targeting retailers, delivery companies, and other companies that rely on handheld computing. Unlike Windows Phone, Windows Embedded Handheld retains backward compatibility with legacy Windows Mobile applications. Pocket PCs and personal digital assistants were originally the intended platform for Windows Mobile. These were grouped into two main categories: devices that lacked mobile phone capabilities, and those that included it. Beginning with version 6 devices with this functionality ran "Windows Mobile 6 Professional" and those that lacked it ran "Windows Mobile 6 Classic". Microsoft had described these devices as "a handheld device that enables you to store and retrieve e-mail, contacts, appointments, play multimedia files, games, exchange text messages with MSN Messenger, browse

2470-399: Is the default office suite . Internet Connection Sharing , supported on compatible devices, allows the phone to share its Internet connection with computers via USB and Bluetooth. Windows Mobile supports virtual private networking over PPTP protocol. Most devices with mobile connectivity also have a Radio Interface Layer . The Radio Interface Layer provides the system interface between

2565-596: The Intel i386 in 1990. Microsoft also continued parallel development of the DOS-based and less resource -demanding Windows environment, resulting in the release of Windows 3.0 in May 1990. Windows 3.0 was eventually so successful that Microsoft decided to change the primary application programming interface for the still unreleased NT OS/2 (as it was then known) from an extended OS/2 API to an extended Windows API . This decision caused tension between Microsoft and IBM and

2660-522: The Pocket PC keyboard-less PDAs in 2000, with Pocket PC 2000 being the software. It was based on version 3.0 of Windows CE, the operating system originally developed for the Handheld PC in 1996. The next versions were Pocket PC 2002 and Smartphone 2002, the latter of which would power a new category of keypad-based cell phone devices named Smartphone. With the release of Windows Mobile 2003 ,

2755-752: The PowerPC processor in 1995, specifically PReP -compliant systems such as the IBM ThinkPad Power Series laptops and Motorola PowerStack series; but despite meetings between Michael Spindler and Bill Gates, not on the Power Macintosh as the PReP compliant Power Macintosh project failed to ship. Intergraph Corporation ported Windows NT to its Clipper architecture and later announced an intention to port Windows NT 3.51 to Sun Microsystems ' SPARC architecture, in conjunction with

2850-590: The Windows 8 -derived Windows RT on October 26, 2012, and the use of Windows NT, rather than Windows CE, in Windows Phone 8 . The original Xbox and Xbox 360 run a custom operating system based upon a heavily modified version of Windows 2000 , an approach that Microsoft engineer Don Box called "fork and run". It exports APIs similar to those found in Microsoft Windows , such as Direct3D . The Xbox One and Xbox Series X/S consoles use

2945-541: The Windows CE 5.x kernel, intended to bridge the gap between version 6.1 and the then yet-to-be released Windows Mobile 7 (Later canceled in favor of Windows Phone 7), that arrived in 2010. It was never part of Microsoft's mobile phone roadmap, and has been described by its chief executive, Steve Ballmer , as "not the full release Microsoft wanted" until the multi-touch -enabled Windows Mobile 7 (now replaced by Windows Phone ) arrived in 2010. Ballmer also indicated that

Since Windows Vista, the Windows installation files, as well as the preinstallation environment used to install Windows, are stored in the Windows Imaging Format . It is possible to use the Deployment Image Servicing and Management (DISM) tool to install Windows from

3135-511: The Alpha NT 5 (Windows 2000) release had reached RC1 status. On January 5, 2011, Microsoft announced that the next major version of the Windows NT family will include support for the ARM architecture . Microsoft demonstrated a preliminary version of Windows (version 6.2.7867) running on an ARM-based computer at the 2011 Consumer Electronics Show . This eventually led to the commercial release of

3230-554: The CPU, as in Windows 3.1 Windows applications (although MS-DOS applications were preemptively multitasked in Windows starting with Windows/386 ). Notably, in Windows NT 3.x, several I/O driver subsystems, such as video and printing, were user-mode subsystems. In Windows NT 4.0, the video, server, and printer spooler subsystems were moved into kernel mode. Windows NT's first GUI was strongly influenced by (and programmatically compatible with) that from Windows 3.1; Windows NT 4.0's interface

3325-632: The Cell Core layer within the Windows Mobile OS and the radio protocol stack used by the wireless modem hardware. This allows OEMs to integrate a variety of modems into their equipment. The user interface changed dramatically between versions, only retaining similar functionality. The Today Screen , later called the Home Screen , shows the current date , owner information, upcoming appointments, e-mails, and tasks . The taskbar displays

3420-476: The DEC Alpha. Windows NT and VMS memory management , processes , and scheduling are very similar. Windows NT's process management differs by implementing threading , which DEC did not implement until VMS 7.0 in 1995. Like VMS, Windows NT's kernel mode code distinguishes between the "kernel", whose primary purpose is to implement processor- and architecture-dependent functions, and the "executive". This

Early models of the TyTN (HT624xxx - HT632xxx) have been known to suffer from screen alignment problems and should be avoided. Windows Mobile Windows Mobile

3705-589: The Version API Helper functions' behavior. If an application is not manifested for Windows 8.1 or later, the API will always return version 6.2, which is the version number of Windows 8 . This is because the manifest feature was introduced with Windows 8.1, to replace GetVersion and related functions. In order to prevent Intel x86 -specific code from slipping into the operating system, due to developers being used to developing on x86 chips, Windows NT 3.1

3800-532: The Web, and more". From a technical standpoint Microsoft also specified various hardware and software requirements such as the inclusion of a touchscreen and a directional pad or touchpad. Smartphones were the second hardware platform after Pocket PC to run Windows Mobile, and debuted with the release of Pocket PC 2002. Although in the broad sense of the term "Smartphone", both Pocket PC phones and Microsoft branded Smartphones each fit into this category. Microsoft's use of

Once all the boot and system drivers have been loaded, the kernel starts the Session Manager Subsystem . This process launches winlogon , which allows the user to login. Once the user is logged in File Explorer is started, loading the graphical user interface of Windows NT. Windows NT is written in C and C++ , with

4275-648: The bundled version of Office Mobile include a spell checker and word count tool in Pocket Word and improved Pocket Outlook . Connectivity was improved with file beaming on non-Microsoft devices such as Palm OS , the inclusion of Terminal Services and Virtual private networking support, and the ability to synchronize folders. Other upgrades include an enhanced UI with theme support and savable downloads and WAP in Pocket Internet Explorer . Smartphone 2002, originally codenamed "Stinger",

4370-452: The collaboration ultimately fell apart. IBM continued OS/2 development alone while Microsoft continued work on the newly renamed Windows NT. Though neither operating system would immediately be as popular as Microsoft's MS-DOS or Windows products, Windows NT would eventually be far more successful than OS/2. Microsoft hired a group of developers from Digital Equipment Corporation led by Dave Cutler to build Windows NT, and many elements of

4465-450: The command line and skip the GUI installer. It has been suggested that Dave Cutler intended the initialism "WNT" as a play on VMS , incrementing each letter by one . However, the project was originally intended as a follow-on to OS/2 and was referred to as "NT OS/2" before receiving the Windows brand. One of the original NT developers, Mark Lucovsky , states that the name was taken from

4560-721: The company "screwed up with Windows Mobile", he lamented that Windows Mobile 7 was not yet available and that the Windows Mobile team needed to try to recoup losses. Microsoft unveiled this version at the 2009 Mobile World Congress in February, and several devices were supplied with it. It was released to manufacturers on May 11, 2009; the first devices running the operating system appeared in late October 2009. Several phones that officially shipped with Windows Mobile 6.1 can be officially updated to Windows Mobile 6.5. This update includes some significant new added features, such as

4655-660: The company's planned introduction of UltraSPARC models in 1995, but neither version was sold to the public as a retail product. Only two of the Windows NT 4.0 variants (IA-32 and Alpha) have a full set of service packs available. All of the other ports done by third parties (Motorola, Intergraph, etc.) have few, if any, publicly available updates. Windows NT 4.0 was the last major release to support Alpha, MIPS, or PowerPC, though development of Windows 2000 for Alpha continued until August 1999, when Compaq stopped support for Windows NT on that architecture; and then three days later Microsoft also canceled their AlphaNT program, even though

4750-703: The current time as well as the volume level. Devices with a cellular radio also show the signal strength on said taskbar. Windows Mobile is based on the Windows CE kernel and first appeared as the Pocket PC 2000 operating system. It includes a suite of basic applications developed with the Microsoft Windows API , and is designed to have features and appearance somewhat similar to desktop versions of Windows . It allowed third party developers to develop software for Windows Mobile with no restrictions imposed by Microsoft. Software applications were purchasable from Windows Marketplace for Mobile during

4845-401: The design reflect earlier DEC experience with Cutler's VMS , VAXELN and RSX-11 , but also an unreleased object-based operating system developed by Cutler at Digital codenamed MICA . The team was joined by selected members of the disbanded OS/2 team, including Moshe Dunie . Although NT was not an exact clone of Cutler's previous operating systems, DEC engineers almost immediately noticed

4940-691: The device must run an ARM compatible processor such as the Intel XScale or the Samsung and Texas Instruments ARM compatibles. Windows Mobile 6, formerly codenamed "Crossbow", was released on February 12, 2007 at the 3GSM World Congress 2007 and was based on the Windows CE 5.2 kernel. It comes in three different versions: "Windows Mobile 6 Standard" for Smartphones (phones without touchscreens), "Windows Mobile 6 Professional" for Pocket PCs with phone functionality, and "Windows Mobile 6 Classic" for Pocket PCs without cellular radios. Windows Mobile 6

5035-521: The executive. Routines from each are directly accessible, as for example from kernel-mode device drivers. API sets in the Windows NT family are implemented as subsystems atop the publicly undocumented "native" API ; this allowed the late adoption of the Windows API (into the Win32 subsystem). Windows NT was one of the earliest operating systems to use UCS-2 and UTF-16 internally. Windows NT uses

5130-488: The hardware side of the Windows CE OS, attempting to create a form factor similar to a PC-esque PDA like WinPad, with communications functionality like Pulsar. Under the name Handheld PC , a hardware reference guide was created, and devices began shipping in 1996, although most of these devices bore little resemblance to the goal of a pen-based touchscreen handheld device. A specification for a smaller form factor under

5225-544: The internal similarities. Parts of VAX/VMS Internals and Data Structures , published by Digital Press , accurately describe Windows NT internals using VMS terms. Furthermore, parts of the NT codebase's directory structure and filenames matched that of the MICA codebase. Instead of a lawsuit, Microsoft agreed to pay DEC $ 65–100 million, help market VMS, train Digital personnel on Windows NT, and continue Windows NT support for

5320-755: The last released version is 6.5.5. It first leaked in January 2010, and was unofficially ported to some Windows Mobile phones. The name Windows Mobile 6.5.5 has been applied to these newer builds, although this name remained unconfirmed by Microsoft. There are three main versions of Windows Mobile for various hardware devices. Windows Mobile Professional , which runs on smartphones with touchscreens; Windows Mobile Standard , which runs on mobile phones without touchscreens; and Windows Mobile Classic , which runs on personal digital assistant or Pocket PCs . Windows Mobile for Automotive and Windows Mobile software for Portable Media Centers are among some specialty versions of

5415-432: The latest version of Windows based on Windows NT being Windows 11 in 2021. The name "Windows NT" originally denoted the major technological advancements that it had introduced to the Windows product line, including eliminating the 16-bit memory access limitations of earlier Windows releases such as Windows 3.1 and the Windows 9x series. Each Windows release built on this technology is considered to be based on, if not

5510-445: The name Palm-size PC was released in 1998. Pocket PC 2000, originally codenamed "Rapier", was released on April 19, 2000, and was based on the Windows CE 3.0 kernel. Pocket PC 2000 was the debut of what was later to become the Windows Mobile operating system, and was meant to be a successor to the operating system aboard Palm-size PCs . Backwards compatibility was retained with such Palm-size PC applications. Pocket PC 2000

5605-571: The names of releases from Windows 2000 and later, though Microsoft described that product as being "Built on NT Technology". "NT" was a trademark of Northern Telecom (later Nortel ), which Microsoft was forced to acknowledge on the product packaging. One of the main purposes of NT is hardware and software portability. Various versions of NT family operating systems have been released for a variety of processor architectures, initially IA-32 , MIPS , and DEC Alpha , with PowerPC , Itanium , x86-64 and ARM supported in later releases. An initial idea

5700-470: The next major releases, in 2007 and 2008 respectively, by which time the hardware devices were also solely under the Windows Mobile banner. Along with the final major release, Windows Mobile 6.5 , the first to be designed for use without a stylus on touchscreens, Microsoft also introduced the Windows Marketplace for Mobile for software distribution, for Windows Mobile 6.x devices. Following

5795-414: The original target processor—the Intel i860 , code-named N10 ("N-Ten"). A 1991 video featuring Bill Gates and Microsoft products specifically says that "Windows NT stands for 'New Technology'". Seven year later in 1998, during a question-and-answer (Q&A) session, he then revealed that the letters were previously expanded to such but no longer carry any specific meaning. The letters were dropped from

5890-496: The platform. Microsoft had over 50 handset partners, when Windows Mobile was still being shipped on new devices. 80% of the 50 million Windows Mobile devices that were made from launch to February 2009 were built by one contract manufacturing group, HTC , which makes handsets for several major companies under their brands, and under its own brand. On January 10, 2011, Microsoft announced Windows Embedded Handheld 6.5. The operating system has compatibility with Windows Mobile 6.5 and

5985-401: The platform. Some devices featured slideout keyboards, while others featured minimal face buttons. Microsoft's work on handheld portable devices began with research projects in 1990, with the work on Windows CE beginning in 1992. Initially, the OS and the user interface were developed separately. With Windows CE being based on Windows 95 code and a separate team handing the user interface which

6080-418: The service's lifespan. Most early Windows Mobile devices came with a stylus , which can be used to enter commands by tapping it on the screen. The primary touch input technology behind most devices were resistive touchscreens which often required a stylus for input. Later devices used capacitive sensing which does not require a stylus. Along with touchscreens, a large variety of form factors existed for

6175-576: The software was rebranded to a single "Windows Mobile" for both Pocket PCs and Smartphones, and to connect the brand with its desktop counterpart. Support for SH-3 and MIPS processor architectures were dropped, focusing only on ARM . In the next major release, Windows Mobile 5.0 in 2005, Microsoft unified the separate developments of Pocket PC and Smartphone software into a single Windows Mobile codebase. Data could be synchronized with desktops using ActiveSync software, and later using Windows Mobile Device Center . Windows Mobile 6.0 and 6.1 were

6270-404: The success of newer mobile operating systems like iOS , Windows Mobile faded rapidly; in 2010, Microsoft announced the more modern and consumer-focused Windows Phone 7 as its replacement, and Windows Mobile has been deprecated since existing devices and software are incompatible with Windows Phone . Most versions of Windows Mobile have a standard set of features, such as multitasking and

6365-469: The term "Smartphone" includes only more specific hardware devices that differ from Pocket PC phones. Such Smartphones were originally designed without touchscreens , intended to be operated more efficiently with only one hand, and typically had lower display resolution than Pocket PCs. Microsoft's focus for the Smartphone platform was to create a device that functioned well as a phone and data device in

6460-486: The transition period. 6.5.1 brings larger user interface elements, including icon based soft buttons (rather than text based), an updated contacts app, native support for A-GPS , improved threaded text messaging, and performance improvements. It was unofficially ported to several Windows Mobile phones. The second minor update was announced on February 2, 2010, along with the Sony Ericsson Aspen which

The version of Windows CE in WM 6.0 is 5.2.*, where the third and final number being a four-digit build ID (e.g. 5.2.1622 on HTC Wing). In WM 6.1, the CE version is 5.2.* with a five-digit build number (e.g. 5.2.19216 on Palm Treo 800w). Windows Mobile 6.5 is a stopgap update to Windows Mobile 6.1, based on

6745-660: Was added. Multimedia improvements included MIDI file support as ringtones in Phone Edition and Windows Media Player 9.0 with streaming optimization. A puzzle game titled Jawbreaker is among the preinstalled programs. GAPI was included with this release to facilitate the development of games for the platform. Other features/built-in applications included the following: enhanced Pocket Outlook with vCard and vCal support, improved Pocket Internet Explorer and SMS reply options for Phone Edition. Windows Mobile 2003 Second Edition, also known as "Windows Mobile 2003 SE",

6840-418: Was also bundled and included Pocket Word, Pocket Excel and Pocket Outlook. Notes, a note-taking app saw its first release and would be supported by most later versions of Windows Mobile. Intelligent character recognition support allowed Notes to distinguish styles of handwriting to be learned by the OS during processing to improve accuracy and recognition levels. Pocket PC 2002, originally codenamed "Merlin",

6935-612: Was announced April 1, 2008, and was based on the Windows CE 5.x kernel. It is a minor upgrade to the Windows Mobile 6 platform with various performance enhancements and a redesigned Home screen featuring horizontal tiles that expand on clicking to display more information, although this new home screen is featured only on Windows Mobile Standard edition. This was not supported in the Professional edition. Several other changes such as threaded SMS , full page zooming in Internet Explorer and 'Domain Enroll' were also added, along with

7030-423: Was cancelling plans to ship 64-bit Windows for Alpha. Because of this, Alpha versions of Windows NT are 32-bit only. While Windows 2000 only supports Intel IA-32 (32-bit), Windows XP, Server 2003, Server 2008 and Server 2008 R2 each have one edition dedicated to Itanium-based systems. In comparison with Itanium, Microsoft adopted x64 on a greater scale: every version of Windows since Windows XP (which has

7125-454: Was codenamed WinPad (later Microsoft At Work for Handhelds). Windows 95 had strong pen support making porting easy; with some saying "At this time, Windows 95 offers outstanding pen support. It is treating pens right for the first time." WinPad was delayed due to price and performance issues, before being scrapped in early 1995 due to touchscreen driver problems relating to WriteTouch technology, made by NCR Microelectronic Products. Although WinPad

7220-459: Was designed as a modified microkernel , as the Windows NT kernel was influenced by the Mach microkernel developed by Richard Rashid at Carnegie Mellon University, but does not meet all of the criteria of a pure microkernel. Both the kernel and the executive are linked together into the single loaded module ntoskrnl.exe ; from outside this module, there is little distinction between the kernel and

7315-603: Was designed mainly for easier finger usage. Some reviewers have noted interface inconsistencies, with some applications having small buttons making them harder to operate using only a finger. Whilst this version of Windows Mobile does not natively support capacitive screens , mobile manufacturers have been able to use them on their devices. In the months following this release, development shifted from Windows Mobile to its successor Windows Phone. As such no major upgrades were planned or released, although three minor updates; 6.5.1, 6.5.3 and 6.5.5; were made to satisfy consumers during

7410-418: Was enhanced with Picture and Video package, which converged the management of videos and pictures and Windows Media Player 10 Mobile. Among new hardware features were enhanced Bluetooth support, default QWERTY keyboard-support and a management interface for Global Positioning System (GPS). Improvements were made to ActiveSync 4.2 with 15% increased synchronization speed. Business customers benefited from

7505-624: Was first offered on the Dell Axim x51. It used the .NET Compact Framework 1.0 SP3, an environment for programs based on .NET. Windows Mobile 5.0 included Microsoft Exchange Server "push" functionality improvements that worked with Exchange 2003 SP2. The "push" functionality also required vendor/device support. With AKU2 software upgrades all WM 5.0 devices supported DirectPush . Other features included an enhanced battery-saving capability called persistent storage capability. Previously up to 50% (enough for 72 hours of storage) of battery power

7600-523: Was initially developed using non-x86 development systems and then ported to the x86 architecture. This work was initially based on the Intel i860 -based Dazzle system and, later, the MIPS R4000-based Jazz platform. Both systems were designed internally at Microsoft. Windows NT 3.1 was released for Intel x86 PC compatible and PC-98 platforms, and for DEC Alpha and ARC -compliant MIPS platforms. Windows NT 3.51 added support for

7695-402: Was intended mainly for Pocket PC devices; however, several Palm-size PC devices had the ability to be updated as well. Furthermore, several Pocket PC 2000 phones were released (under the name Handheld PC 2000), however at this time, Microsoft's "Smartphone" hardware platform had not yet been created. At this time, Pocket PC devices had not been standardized with a specific CPU architecture. As

7790-483: Was never released as a consumer product, Alpha builds were released showcasing many interface elements. During development of WinPad a separate team worked on a project called Pulsar; designed to be a mobile communications version of WinPad, described as a "pager on Steroids". This project was also canceled around the same time as WinPad. The two disbanded groups would form the Pegasus project in 1995. Pegasus would work on

7885-482: Was powered by the same OS as with Windows Mobile 2003, which was Windows CE 4.20. Windows Mobile 5.0, originally codenamed "Magneto", was released at Microsoft's Mobile and Embedded Developers Conference 2005 in Las Vegas, May 9–12, 2005, and was based on the Windows CE 5.0 kernel. Microsoft offered mainstream support for Windows Mobile 5 through October 12, 2010, and extended support through October 13, 2015. It

7980-419: Was redesigned to match that of the brand-new Windows 95 , moving from the Program Manager to the Windows shell design. NTFS , a journaled, secure file system, is a major feature of NT. Windows NT also allows for other installable file systems; NT can also be installed on FAT file systems, and versions 3.1, 3.5, and 3.51 could be installed HPFS file systems. Windows NT introduced its own driver model,

8075-543: Was released in 2002. Based on Windows CE 3.0 like Pocket PC 2002 and Pocket PC 2000, Smartphone 2002 was built for GSM cell phones with standard keypad-based form factors, as opposed to Pocket PC 2002 Phone Edition which targeted standard touch-based PDAs. The first device that was supposed to ship with Smartphone 2002 was the Sendo Z100 which was canceled after Microsoft sued Sendo. Windows Mobile 2003, initially named as Pocket PC 2003 and originally codenamed "Ozone",

8170-560: Was released on March 24, 2004, and first offered on the Dell Axim x30 . It was based on the Windows CE 4.x kernel. This was the last version which allowed users to back up and restore an entire device through ActiveSync . This upgrade allows users to switch between portrait and landscape modes and introduces a single-column layout in Pocket Internet Explorer . It includes support for Wi-Fi Protected Access (WPA) and new screen resolutions : 640×480 ( VGA ), 240×240, and 480×480. It

8265-558: Was released on October 4, 2001, and was based on the Windows CE 3.0 kernel, like with Pocket PC 2000. Although targeted mainly for 240×320 ( QVGA ) Pocket PC devices, Pocket PC 2002 was also used for Pocket PC phones (Pocket PC 2002 Phone Edition). Aesthetically, Pocket PC 2002 was meant to be similar in design to the then newly released Windows XP . Newly added or updated programs include Windows Media Player 8 with streaming capability; MSN Messenger , and Microsoft Reader 2, with Digital rights management support. Upgrades to

8360-502: Was released, including the new shell from Windows 95 . Eventually, Microsoft incorporated the Windows NT technology into the Windows product line for personal computing and deprecated the Windows 9x family. Starting with Windows 2000 , "NT" was removed from the product name yet is still in several low-level places in the system — including for a while as part of the product version. Versions of Windows NT are installed using Windows Setup , which, starting with Windows Vista , uses

8455-448: Was reserved just to maintain data in volatile RAM. This continued the trend of Windows-based devices moving from using RAM as their primary storage medium to the use of a combination of RAM and flash memory (in use, no distinction between the two is obvious to users). Programs and frequently accessed data run in RAM, while most storage is in the flash memory. The OS seamlessly moves data between

8550-738: Was similar in design to the then-current Windows 98 , Windows 2000 , and the yet-to-be-released Windows Me desktop operating systems. Crucially, the Pocket PC had a less cluttered interface more suitable for a mobile device, unlike the interface on predeceasing Palm-size PCs. Mainstream support for Pocket PC 2000 ended on September 30, 2005, and extended support ended on October 9, 2007. This initial release had multiple built-in applications, many of them similarly branded to match their desktop counterparts; such as Microsoft Reader , Microsoft Money , Pocket Internet Explorer and Windows Media Player . A version of Microsoft Office called Pocket Office

8645-420: Was the first phone to use this version. 6.5.3 continues the trend of attempting to provide a more finger-friendly user interface with several new usability features such as native support for multitouch ; although device maker HTC Corporation created proprietary work-arounds to allow multi-touch to work on some applications it installed on its HD2 handset (However, Microsoft applications on this handset, such as

8740-467: Was the first release under the Windows Mobile banner, released on June 23, 2003, based on the Windows CE 4.2 kernel. It came in four editions: "Windows Mobile 2003 for Pocket PC Premium Edition", "Windows Mobile 2003 for Pocket PC Professional Edition", "Windows Mobile 2003 for Smartphone " and "Windows Mobile 2003 for Pocket PC Phone Edition". The last was designed especially for Pocket PCs which include phone functionalities. The Professional Edition

8835-443: Was to have a common code base with a custom Hardware Abstraction Layer (HAL) for each platform. However, support for MIPS, Alpha, and PowerPC was later dropped in Windows 2000 . Broad software compatibility was initially achieved with support for several API "personalities", including Windows API , POSIX , and OS/2 APIs – the latter two were phased out starting with Windows XP. Partial MS-DOS and Windows 16-bit compatibility

8930-691: Was up to the carriers to provide updates to end users. In July 2007, HTC released a generic update to Windows Mobile 6, freely available to the public. In November 2007, AT&T released an update to Windows Mobile 6. Official ROM updates are or were available for several versions of the TyTN, including the AT&;T/Cingular 8525, the Dopod 838Pro, the i-mate JASJAM, the O2 XDA Trion, and the Orange SPV M3100 (AKU 3.3.0). Some of these updates update

9025-548: Was used in Pocket PC budget models. It lacked a number of features that were in the Premium Edition, such as a client for L2TP/IPsec VPNs. All versions of Windows Mobile 2003 were powered by Windows CE 4.20. Communications interface were enhanced with Bluetooth device management, which allowed for Bluetooth file beaming support, Bluetooth headset support and support for Bluetooth add-on keyboards. A pictures application with viewing, cropping, e-mail, and beaming support
