Windows update KB5043145 caused some users to experience the blue screen of death instead of performance improvements. Before rolling back updates, users should check for adequate hard drive space, restart the system, attempt to reinstall updates, disconnect non-essential hardware, check for conflicts in Device Manager, ensure antivirus software is not interfering, and verify that the Windows Update service is activated.
To troubleshoot update issues, Windows 11 users can run the Windows Update troubleshooter from Settings, while Windows 10 users can access it through Update & Security. Users can also utilize system restore points to revert to a previous state, use the Reset Windows Update Tool to repair update components, manually install updates from the Microsoft update catalog, or reset and restart update services via command prompt. If all else fails, reinstalling Windows may be necessary, though it could result in data loss.
