Microsoft issues a fix for Windows 11 Safe Mode problems caused by KB5012643 update
When Microsoft released the KB5012643 update for Windows 11, there were complaints from a number of users about screen flicker when booting into Safe Mode.
Microsoft acknowledged the problem, and confirmed suspicions that it was related to Safe Mode with Networking. The company has now addressed the issue, fixing it with a relatively rare KIR (Known Issue Rollback).
KB5012643 update is causing screen flickering for some Windows 11 users
Installing updates for Windows can often be something of a gamble, but this is particularly true when we're talking about the preview versions Microsoft makes available ahead of the monthly Patch Tuesday releases.
The latest problematic patch is the recently released KB5012643 update for Windows 11. Due for a wider release in May, Microsoft has already made a preview version available for those who like to get updated as soon as possible. But some people who have installed the update are reporting problems with flickering screens.
