Microsoft issues WSUS sync fix and manual mitigation
🛠️ Microsoft published manual steps to remediate a WSUS synchronization problem that causes Windows Update scans to fail or time out on affected servers. The issue affects client (Windows 10, v1607+) and server (Windows Server 2012+) platforms and leads to prolonged sync times or operation timeouts due to accumulating publishing metadata. A service-side mitigation was rolled out for new or rebuilt WSUS installations, while administrators with existing servers are advised to back up SUSDB, run cleanup SQL queries, reset MaxXMLPerRequest, reindex SUSDB, run the WSUS Server Cleanup Wizard, and restart IIS or the WsusPool to restore normal sync behavior.
