Alt-Tab and Task View (24H2)

Windows 11 includes two options for quickly switching between open apps and other windows, Alt-Tab and Task view.

Alt-Tab
Alt-Tab is the simplest and oldest multitasking user interface in Windows, and it works much as it did in Windows 10 and previous Windows versions: Type ALT + TAB, but keep holding the ALT key down to display thumbnails of the most recent available apps and other windows to which you can switch the focus.

Use Alt-Tab to switch between open windows
When you open Alt-Tab, the thumbnail for the next window in the z-order--the list of available apps and other windows, listed in the order in which they were most recently accessed--is selected. (Put another way, the window you most recently accessed is selected.) So you can quickly switch to this window by letting go of the ALT key. Alt-Tab closes when you do so.

Indeed, you can quickly toggle between the two most-recently-accessed windows by repeatedly typing ALT + TAB.

To select another window, type ALT + TAB, keep the ALT key held down, and repeatedly tap the TAB key. As you do so, the selection will change. When the window you want is selected, release the ALT key.
You can alternatively type ALT + SHIFT + TAB to move through the Alt-Tab z-order in reverse.
Determine whether Microsoft Edge tabs appear in Alt-Tab
Once you know the keyboard shortcut, Alt-Tab is simple enough to use. But there is one wrinkle that's unique to Windows 11 (and Windows 10): In addition to working with any open apps and other windows, Alt-Tab is configured by default to let you access the three most recently accessed Microsoft Edge tabs as well. So if you use Microsoft Edge, you will see individual browser tabs in Alt-Tab as well.

This may be desirable. But you can configure this feature to work the way you want, including excluding Microsoft Edge tabs from Alt-Tab.

To do so, open Settings (WINKEY + I) and navigate to System > Multitasking. Here, you will find the setting "Show tabs from apps when snapping or pressing Alt+Tab."

The following choices are available:

20 most recent tabs
5 most recent tabs
3 most recent tabs
Don't show tabs

Oddly, there's no mention of Microsoft Edge. But that's what this setting configures: Whether Microsoft Edge tabs appear individually in Alt-Tab and, if so, how many can appear.
Task View
Task view works much like Alt-Tab in that it lets you switch between open apps and other windows (i.e. "tasks"). But it offers some key advantages over Alt-Tab as well. It's persistent and doesn't require the same keyboard gymnastics. It can be accessed via a handy Taskbar item. And it also lets you access Windows 11's virtual desktop feature, called Desktops.
Task view is curiously missing one key feature that's available in Alt-Tab: where Alt-Tab can be configured to display individual Microsoft Edge tabs, Task view cannot. Instead, you will see one thumbnail for Microsoft Edge in Task view.
