Threat Score
Microsoft has acknowledged a WSUS synchronization issue (impacting client Windows 10 1607+ and server Windows Server 2012+) that began in mid-July 2026 and has caused increased sync times and timeouts, preventing affected servers from deploying updates via WSUS or Configuration Manager; mitigations have been applied for new/rebuilt WSUS installations while additional fixes for already-affected servers are being developed.
