Windows 10 users found problems with Alt+Tab after installing KB5005033

KB5005033 is a security update launched by Microsoft to Windows 10. It is precisely because of the security update that this update is mandatory to install.

This update not only adjusts the permissions of the print driver to alleviate related security issues but also performs repairs to some game frame rate drop issues.

However, after installing this update, some users found that this security update would destroy the Alt+Tab function, resulting in failure to switch windows, flickering, or even a black screen.

At present, Microsoft has not yet issued a response to this issue or provided a temporary solution. It is recommended that users who have installed this update do not use the Alt+Tab shortcut for the time being.

“It breaks Alt-Tab switching games that run in “full screen” mode. Switching to such games gives you a black screen and no way to return to the game. Again uninstalling this update reverts to normal working behaviour,” one user noted in the Feedback Hub.

“Furthermore, Windows 10 under this update sometimes Alt-Tabs out of the fullscreen game immediately after starting up the game from Steam. Basically, the fullscreen game now starts up minimized on my taskbar. If I try to click the game to go to its fullscreen mode, Win10 immediately alt-tabs from the fullscreen and I’m back to square one,” another user noted.

Some users have tested and confirmed that uninstalling the KB5005033 update can also solve this problem, but this is a security update so it is not recommended for users to uninstall.

To uninstall, please refer to the following method: Go to the update settings, click Update History, uninstall the update, and then right-click KB5005033.

To fix Alt-Tab issues caused by KB5005033, users can disable News and Interest feed by following these steps:
