Microsoft warns that the KB5012643 update is causing problems with lots of Windows 11 apps


It is not long since Microsoft released the KB5012643 update for Windows 11, bringing with it a lengthy list of improvements and security fixes. But, as has been the case with so many Windows updates, it also brought problems.
We have already seen issues with screen flicker in Safe Mode, although Microsoft has taken steps to address this. But now the company has issued a warning that Windows 11 users may experience issues with certain types of apps after installing the KB5012643 update.
