The default Alt-Tab function of Windows 10 does not seem to work for some users after the release of two updates via Patch Tuesday (July and August 2021).
Update KB5005033 stops the Alt-Tab shortcut from working properly in Windows 10. Using the Alt+Tab shortcut is essential because if you press the Alt-Tab keys together and then continue to press the Tab key, it will start moving through your open windows. When you release the key, the window you are in opens.
