Microsoft has shared manual mitigations to help IT administrators fix Windows Server Update Services (WSUS) servers affected by a known issue that causes Windows Update scans to fail or time out.

This known WSUS sync issue affects both client (Windows 10, version 1,607 and later) and server (Windows Server 2012 and later) platforms.

On impacted WSUS servers, admins are not able to deploy the latest Windows updates via WSUS or Configuration Manager due to increased synchronization times or sync operation timeouts caused by a buildup of publishing metadata.
