On September 26, Microsoft released an optional update for Windows 11, KB5043145, which caused significant booting issues for many users, leading to its retraction. Users reported being trapped in endless boot loops and experiencing unresponsive mice and keyboards. Microsoft has paused the rollout of the update but it remains available for download, with warnings against installation due to potential recovery mode activation after failed boot attempts. Specific laptop models, such as the Asus TUF A15 (2022) and ROG Strix G17 (2024), have been notably affected. The update has also caused errors like the Blue Screen of Death (BSOD) and Green Screen of Death (GSOD). Users have found that reverting to the previous update resolves these issues. Microsoft is investigating the situation and has advised users to uninstall the KB5043145 update. Additionally, the 24H2 update for Windows 11 has been released, which may improve stability.
