42-624: Task View is a task switcher and virtual desktop system introduced in Windows 10 and is among the first features new to Windows 10 . Task View allows a user to quickly locate an open window, quickly hide all windows and show the desktop, and to manage windows across multiple monitors or virtual desktops. Clicking the Task View button on the taskbar or swiping from the left side of the screen displays all open windows and allows users to switch between them, or switch between multiple workspaces. It

84-627: A document is selected using Alt + Tab ↹ : first an icon representing the main Reader window and then an icon for the individual document. While in Adobe Reader, pressing Alt + Tab ↹ one time selects the second item in the list, which is the icon for the PDF document. Adobe Reader remains the current task when Alt + Tab ↹ is released. Thus it is demonstrated that the correct operation of Alt + Tab ↹ , like some other aspects of

126-438: A fast Alt + Tab ↹ with all keys released immediately) is precisely a special case of the above behavior. Suppose the windows are A B C and we want to alternate between A and B . Hold Alt while pressing and releasing Tab; continue holding Alt. The list will show A B C and the cursor will initially be over B . When Alt is released B will be selected, Tab having been pressed a total of 1 time, and zero attention to

168-407: A few similar features of its own: Windows 3.0 first introduced a window switcher in 1990. Using Alt + Tab ↹ , users could see a flattened view of all open windows. Every version of Windows since then has also provided this window switching functionality. Windows Vista and Windows 7 provide an additional feature called Windows Flip 3D , which has a broadly similar purpose. Flip 3D allows

210-581: A full-size window and the desktop. The window environment maintains a Z-order list of top-level windows (tasks) with the most recently used tasks at the front and the desktop at the bottom, so the most recently used tasks can be switched to the most quickly. The Alt + Tab ↹ keyboard combination has also been incorporated in other operating systems and desktop environments such as KDE , Xfce , and GNOME . iOS and macOS have similar functionality by pressing ⌘ Command + Tab ↹ but that switches applications rather than windows . The use of

252-591: A helper application such as bbkeys . Compiz Fusion (aka Beryl , Compiz ) has similar functionality, but displays a preview of the window as well as its icon (Present in Windows Vista and above, with DWM enabled). It also makes use of Alt-Shift-Tab by moving backwards through the displayed programs, and it is possible to activate a Windows Flip 3D alternative using the Windows key and Tab. The Metacity window manager has similar functionality to versions of Windows released before Vista, but it only displays

294-475: A list of all windows in a fixed order, or opening a task applet in which one has to use arrow keys or the mouse to select a task and then click or push Enter. Some window managers such as WindowLab forego the onscreen window list and simply bring each window to the front in turn as Alt + Tab ↹ is pressed. Not all window managers provide this functionality as a core feature. For example, Blackbox does not; users desiring this behavior can add it by running

336-615: A low-level keyboard hook. Such a technique is used by applications such as the Virtual Network Computing (VNC) viewer to pass Alt + Tab ↹ keystrokes to the remote desktop when the VNC window is active. Under Windows XP , the Tweak UI PowerToy, can adjust the number of rows and columns in the task list window, or it can be adjusted via a registry edit. This is helpful if there are so many windows that

378-572: A public API that allows any application to access the same thumbnail representations that Flip3D uses, and so there are a number of third party add-ons that are able to provide this functionality in Vista. A very few third-party applications, such as the Emcee Desktop Organizer, provide organization of similar windows into visual "stacks," or support Windows 8 's "Immersive" Apps. Microsoft's Intellipoint Software for Microsoft Mice has

420-405: A similar feature as it also works with live images of windows, rather than a static representations. Additionally, several freeware Windows applications exist to emulate the functionality. Task switcher Alt + Tab ↹ orders windows by most recently used , thus repeated Alt + Tab ↹ keystrokes will switch between the two most recent tasks. It can also be used alternate between

462-488: A switcher dialog similar to that in XP, one can keep Left- Alt pressed, tap on Right- Alt and then press Tab ↹ . There is a common problem associated with the use of Alt + Tab ↹ . It is very easy for the user to mistakenly use Alt + ⇧ Shift instead, changing the system language through the use of a default keybind. To solve this issue, go into Control Panel/Regional Settings/Languages/Details and there

504-445: A user to flip through all open windows with a 3D perspective. A downside to this method is that the front most window covers a significant portion of the other windows. On the other hand, this allows the user to see the contents of the front most window, while this can be difficult in similar applications that show the open windows in a grid, especially if the user has a large number of windows open. Vista's Desktop Window Manager exposes

546-465: A way to switch out of a full-screen application, since the desktop is no longer a window. If the user prefers the smaller XP icons over the larger Vista "thumbnail" icons, they can change the functionality by: The user may also stop the Dwm.exe process via Windows' Task Manager . In Windows 7 Alt + Tab ↹ , after a one-second delay, displays the full-sized application window immediately each time

588-421: Is a button that allows the user to configure the shortcuts to switch languages - he/she can disable it or change it to something harder to press by mistake. This problem is reported on Windows XP and Windows 7. Similar functionality exists on macOS using ⌘ Command instead of Alt , and switching between applications rather than windows. The Mac's switcher has the additional capabilities of pointing at

630-528: Is altered by the creation and destruction of windows, programmatic hiding, showing, raising, and lowering of windows, and alterations to the window z-order . The order of the Alt + Tab ↹ list corresponds directly to the z-order, once the windows have been sorted according to 'always-on-top' status. Alt-Shift-Esc is equivalent to one Alt-Shift-Tab except that minimized windows are selected without being displayed. Alt + Tab ↹ works even if Windows Explorer

672-551: Is guaranteed to be first in the list. Suppose the complete list is A W Z E U B C . The selection cursor will initially be on W . Suppose we want to switch to window U . Without releasing Alt, press Tab three more times and then release Alt. Then hold down Alt and press-release Tab once leaving Alt down. The window list will now show U A W Z E B C . Then Tab over to E and release Alt, selecting window E . Press and hold down Alt and press-release Tab once leaving Alt down. The window list will now show E U A W Z B C . Note that

714-454: Is no longer running. On Windows NT 3.51 and prior, Alt + Tab ↹ is managed by CSRSS (Client/Server Runtime Subsystem). On Windows NT 4.0 and later, it's handled by the kernel mode windowing system driver (win32k.sys). It works even when Ctrl + Alt + Del and Ctrl + ⇧ Shift + Esc ( Task Manager ) (which are managed by Winlogon ) do not. Alt + Tab ↹ may be intercepted (or effectively disabled) by means of

756-411: Is pressed twice, and so on for all tasks. The priority of a window in terms of Alt + Tab ↹ accessibility is how recently it was used. If A is now minimized, the list will become E U W Z B C A , and if Z is minimized the list becomes E U W B C A Z . Thus minimizing a window mimics the effect of not using it for a long time. The commonplace alternation between the 2 most recent tasks (using

798-486: Is to download and run a program which will remove these flags. download To show the XP icons in Windows 7 advanced users can add a new DWORD value AltTabSettings in the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ and set its value to 1. Using Windows 7 the additional key combination Ctrl + Alt + Tab ↹ brings up the switcher dialog and it remains on screen after all

840-478: Is visible, windows can be selected and made active by clicking on them with the mouse, and the list can be scrolled forward or backward using the mouse scroll wheel. If there is only one window on the system, Windows does not show a selector dialog at all when Alt + Tab ↹ is pressed; the key sequence will simply restore or give focus to that window in case it is minimized or not focused. This means that under Windows 10, Alt + Tab ↹ no longer functions as

882-400: The modifier key Alt in using Alt + Tab ↹ differs from typical modifier key use in the following ways: There are many subtleties to the behavior of Alt + Tab ↹ , and they have remained mostly unchanged over the years. The behavior follows these rules: The rules have the following consequences: When the task list is initially activated by pressing Alt + Tab ↹ ,

924-480: The 'group similar taskbar buttons' setting which is enabled by default). Windows 10 removed the desktop from the task list. Windows may be divided into two categories, 'always-on-top' and ordinary. When a task is switched to, it is moved to the head of its category. For the following example, suppose there are no 'always-on-top' windows. Let A be the current window title. Hold down Alt and press and release Tab once, leaving Alt pressed. The window list comes up. A

966-453: The Alt key was released. An example of a program that violates the expectation that pressing Alt + Tab ↹ one time will switch to the previous application is Adobe Reader 7.0.x. Like newer versions of Microsoft Word it attempts to give a separate icon in the Alt + Tab ↹ task menu to each MDI document. However, unlike Word, it brings two items to the front of the list whenever

1008-632: The Command button. This will restore the most relevant window in the application. There was no default key binding for application switching in Classic Mac OS . Third party control panels (such as ApplWindows and LiteSwitch ) provided this behavior. iOS adds comparable functionality using ⌘ Command instead of Alt , as with macOS. The iOS switcher allows the user to move between recently used applications (nine in landscape, six in portrait), as opposed to "open" applications, since

1050-558: The concept of an open application is considerably less clear on iOS than other desktop operating systems. ⌘ Command + ⇧ Shift + Tab ↹ cycles backwards, as in OS X. Unix-like desktop systems such as fvwm , KDE , Xfce , and GNOME have added a compatible function. On some systems including Sun's CDE and old versions of fvwm , the Alt + Tab ↹ key combination is mapped to less sophisticated functionality such as only alternating between two windows, cycling forward or backward in

1092-648: The cursor position changes, hiding all other windows. This is a part of Aero Peek feature, new in Windows 7. This behavior can be disabled along with Aero Peek: Control Panel - Performance Information and Tools - Adjust visual effects - uncheck Enable Aero Peek. Delay is adjustable by setting the LivePreview_ms value in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AltTab registry key. Some users report that

1134-506: The desired icon with the mouse (also present in Windows Vista and above), and dropping files on applications' icons. Selected application can be hidden or closed using H or Q keys without closing the menu. ⌘ Command + ` works similarly to switch between windows within the same application. Once ⌘ Command + Tab ↹ has been invoked, ⌘ Command + ` changes behavior to mimic ⌘ Command + ⇧ Shift + Tab ↹ (i.e. it cycles backwards). Using ↑ or ↓ allows

1176-492: The gadgets), the problem disappears. After restarting sidebar the problem appears again. This bug also happens when ipoint.exe, the Microsoft Intellipoint mouse driver, is running. Other programs causing this behaviour were reported as well. The actual reason this problem occurs is because [zero-sized always-on-top windows at (0,0)] cause Windows Explorer to set the alt-tab properties incorrectly. The solution

1218-401: The keys have been released. A user can move through the dialog in any direction using the arrow keys, or Tab ↹ through in a linear manner, wrapping at the end of the list back to the beginning. In this mode, the ↵ Enter key or a mouse click selects the desired window which gains the focus and the dialog is dismissed; Esc dismisses with no change of focus. In Windows 7 , to use

1260-499: The list is populated in this order: The task list does not change order while it is open, but the order of tasks can change between invocations of the task list. Windows Vista changed the default behavior (under most default installations) with its Flip interface. The six most recently used items in the Flip order work as described, then remaining windows are ordered alphabetically by application path (and optionally grouped, depending on

1302-611: The list would spill over into multiple pages. Another Microsoft PowerToy, Alt + Tab ↹ Replacement , is available for Windows XP that displays a screenshot of each application in the task list rather than just its icon, and allows the user to use the mouse to select the desired application. A more advanced version of this functionality, named Windows Flip, is built into Windows Vista . A number of third-party tools, similar to Alt + Tab ↹ Replacement, are also available that add additional functionality to Alt + Tab ↹ . Additionally, Windows Vista and Windows 7 allow

1344-435: The minimized program. Failures such as this can result in a frenzied reordering of the Alt + Tab ↹ list by means of several Alt + Tab ↹ - Tab ↹ - Tab ↹ ... sequences to compensate for the program misbehavior. The algorithm for this reshuffling is intuitive after using for a long time. If the user attempts to switch to an application using Alt + Tab ↹ but the application fails to update its place in

1386-496: The outline of the currently selected window on the screen. Windows, on the other hand shows the whole selected window, which helps the user to pick the correct window from multiple windows with a similar title or icon. The Alt + Tab ↹ key combination to switch between windows has been present in all versions of Windows since Windows 1.0 . However, there was no visual indication of the list of windows available when switching between windows until Windows 3.1 , when this feature

1428-414: The switcher dialog does not stay on top while it is displayed, but one can navigate through this dialog using mouse even if it is completely overlapped by some window. This bug is reported to be user profile specific. Some user profiles on the same machine may encounter this bug, some not. As discovered, the problem is sometimes caused by desktop gadgets system. After killing sidebar.exe process (which hosts

1470-448: The task list window can be observed to flicker for a split second, so . If the user has been switching among 3 applications and wants to dispense with one of them by minimizing, one of the remaining ones will be on top immediately after minimizing, and ordinarily Alt + Tab ↹ will alternate between the 2 remaining windows. If a program fails to move to the end of the list when minimized, pressing Alt + Tab ↹ once will return to

1512-410: The task selection cursor having been necessary. Again, press and release Tab while holding Alt. The list will show B A C and the cursor will initially be over A . When Alt is released we have switched back to A . Displaying the list again, the order has returned to A B C and this sequence can recur. On close inspection, in the course of typing Alt + Tab ↹ and releasing both keys quickly,

1554-462: The user to navigate through the Alt + Tab ↹ menu using mouse or arrow keys. When the Aero Glass theme is enabled, Windows Vista also offers a 3D view of the windows themselves that animates as the user cycles through it. The behaviour is very similar to Alt + Tab ↹ and is accessed by holding down the ⊞ Win key instead of Alt while pressing Tab ↹ . While this view

1596-479: The user to select the window to focus on. The ← and → arrow keys may also be used to navigate the application switcher. This functionality does not automatically restore windows from an application in which all windows been minimized. To restore a window, one needs to press ⌘ Command + Tab ↹ as many times as necessary to choose the desired application, and hold the Option key just prior to releasing

1638-411: The windows switched to with Alt + Tab ↹ ( E , U , A ) are in order of how recently they were switched to. Now Tab over to A and release Alt. Press and hold down Alt and press-release Tab leaving Alt down. The window list will show A E U W Z B C . The effect of this most-recently used behavior is that to return to the most recent task, Tab is pressed once, for the second most recent task Tab

1680-402: The z-order (for example, if its window procedure is hung), then the next time Alt + Tab ↹ is invoked, the task selection cursor may initially point unexpectedly far into the list of icons, just past the application in question, which will not have been moved to the head of the list. Applications have some say in where they are located in the Alt + Tab ↹ order. The list of windows

1722-399: Was first previewed on September 30, 2014, at a Windows 10 press event in downtown San Francisco . A redesigned Task View with support for giving different wallpapers on each desktop has been introduced in Windows 11 . Similar effects are used on other operating systems and programs like X Window System , macOS 's Mission Control , GNOME 3, and ChromeOS . However, Microsoft has provided

1764-477: Was introduced as the 'Fast "Alt+TAB" Switching' checkbox in the Display control panel applet, internally known as "CoolSwitch". Before CoolSwitch, the Alt + Tab ↹ combination was similar to the Alt + Esc combination (which also switched windows), but Alt + Esc redrew each window immediately on each stroke, while Alt + Tab ↹ brought the windows to the top but did not redraw them until
