About this tag
WSUS, or Windows Server Update Services, is a Microsoft enterprise tool for managing and distributing Windows updates within an organization. Recent discussions on WindowsForum highlight a significant WSUS synchronization service degradation that began around July 13, 2026, caused by a buildup of publishing metadata on Microsoft's side. This issue has led to delays and timeouts when WSUS servers attempt to sync update catalogs, disrupting patch management for many enterprises. Microsoft deployed a fix on July 18 that restores normal sync for new WSUS installations, but older affected servers may require additional recovery steps. The tag also covers related topics like Secure Boot certificate updates and setup updates distributed via WSUS.
