Microsoft has acknowledged that the recent Windows 11 update, KB5043145, released on Thursday, is causing severe problems for some users. This update affects Windows 11 versions 22H2 and 23H3, leading to multiple system restarts, blue screens of death, and system freezes.
Reported Issues
Users have experienced several critical problems after installing the update:
- Repeated system reboots
- Unresponsive devices with blue or green screens
- Automatic activation of the AutoRepair tool
- Triggering of BitLocker recovery in some cases
One of the most concerning issues is the potential for a “boot loop,” a long-standing Windows problem where the computer continuously restarts without user intervention. This can be particularly challenging to diagnose and resolve.
Microsoft’s Response
Microsoft has confirmed they are investigating the issue and will provide updates as more information becomes available. However, no specific timeline for a fix has been announced.
Recent History of Update Problems
This is not an isolated incident for Microsoft. Recent updates have caused various issues:
- Task Manager freezes
- Problems with the Edge browser
- Performance drops and boot issues reported after August 2024 security updates
Potential Solutions
While waiting for an official fix, users can:
- Manually check for pending updates that might contain a fix
- Use the built-in Automatic Repair Tool to attempt to resolve startup issues
Conclusion
As Microsoft works on resolving these issues, users should be cautious when applying the September KB5043145 update. Those experiencing problems should monitor Microsoft’s support channels for further guidance and potential fixes.
