If you tend to download optional updates as soon as possible, Microsoft has just given you another reason not to do it.
As if we needed another reason to hold off on downloading the latest patches before they’ve been tested by a considerable number of people, Microsoft’s most recent Windows Update comes with an unfortunate side effect — it causes blue screens for some users. The blue screen shows up right at boot, citing the “UNSUPPORTED_PROCESSOR” error as the stop code. Here’s what we know, and more importantly, how to make sure this doesn’t affect your PC too.
The issue started popping up right after the latest Windows 11 update, KB5029351, which brought the operating system up to version 22621.2215. The build addresses some issues and brings minor improvements, such as adding a new hover behavior to the search box gleam and improving the reliability of the Search app.
Once users install the update and restart their PC, the computer may bring up a blue screen right at boot, making it pretty impossible to do something about it.
