Microsoft confirms Windows Server Update Services sync delays
BleepingComputer • • technology
Key Points:
- Microsoft is addressing a synchronization issue affecting Windows Server Update Services (WSUS) servers, which has disrupted update deployment for over a week.
- The problem impacts both client (Windows 10 version 1607 and later) and server (Windows Server 2012 and later) platforms, causing increased sync times and operation timeouts.
- Mitigation measures have been implemented for new or rebuilt WSUS servers, restoring normal synchronization, while efforts continue to resolve issues on previously affected servers.
- WSUS, a tool introduced nearly 20 years ago, allows IT admins to manage Microsoft product updates centrally on enterprise networks, but the current issue prevents effective update deployment via WSUS or Configuration Manager.
- This is not the first WSUS disruption, as Microsoft resolved similar synchronization problems in May 2025 and July 2025 affecting Windows update deployments.
