Microsoft tackles WSUS sync delays; mitigations rolled out for new installs

Microsoft says a known WSUS synchronization issue has delayed metadata downloads and blocked deployment of the latest Windows updates via WSUS or Configuration Manager since around July 13, 2026. A mitigation was deployed to restore sync times for new WSUS installations and rebuilds, while engineers continue work to remove affected metadata from existing servers and help customers recover previously impacted environments.

Microsoft and Google Warn of Active WSUS and Windows Service Exploits

A security update for Windows Server Update Service (WSUS) addressing a critical vulnerability has inadvertently disabled hotpatching on some Windows Server 2025 devices. Microsoft has halted the update for hotpatch-enrolled systems and released a new patch (KB5070893) that fixes the vulnerability without disrupting hotpatching. Administrators are advised to pause updates, install the new patch, and monitor their systems for continued security and stability.
