A known issue with WSUS servers causes Windows Update scans to fail or experience timeouts, leading to synchronization delays. Microsoft has published manual mitigation guidance to help administrators resolve these WSUS sync problems. The issue affects WSUS server functionality related to update scanning and synchronization but does not have an official patch or automated fix referenced in the available data. The problem is documented in a Bleeping Computer article summarizing Microsoft's shared manual fixes.

The issue causes Windows Update scans on WSUS servers to fail or time out, which can delay or disrupt the update synchronization process. This may impact the timely deployment of updates to managed Windows systems relying on WSUS, potentially increasing exposure to unpatched vulnerabilities until updates are successfully synchronized and applied.

Microsoft has provided manual mitigation steps to address WSUS synchronization delays and timeouts. Administrators should follow the official guidance shared by Microsoft to manually fix affected WSUS servers. Since no official patch or automated fix is indicated, applying these manual mitigations is currently the recommended course of action. Monitor official Microsoft channels for any future updates or patches.
