Microsoft has shared manual mitigations for WSUS servers affected by a sync issue that causes Windows Update scans to fail or time out. The fix helps organizations clean up excess metadata, restore normal synchronization, and resume deploying Windows updates through WSUS and Configuration Manager. #Microsoft #WSUS #WindowsUpdate
Keypoints
- WSUS servers are experiencing scan failures and sync timeouts.
- The issue affects Windows 10 version 1607 and later, and Windows Server 2012 and later.
- Microsoft first applied a service-side mitigation for newly installed or rebuilt WSUS servers.
- Admins with existing WSUS installations can use manual cleanup steps to remove unneeded metadata.
- After cleanup, later scans should return to normal, though the first scan may take longer.
