Microsoft has identified a service degradation affecting Windows Server Update Services (WSUS). Organizations might experience increased synchronization times or sync operation timeouts on WSUS servers. This issue began in recent days, with heightened impact observed starting July 13, 2026, and service-side mitigation on Saturday July 18, 2026. After this day, synchronization times and sync operations are expected to be restored to normal.
This issue is related to a buildup of publishing metadata which is present on existing WSUS server installations as well as from the service side.
Resolution: There are two parts to the resolution of this issue.
- Organizations with existing WSUS server installations that are experiencing long sync times can benefit from manual steps in order to clean up unneeded metadata. This metadata is present in existing WSUS installations but can be safely removed. Detailed guidance has been provided at the following KB article: https://support.microsoft.com/help/5121986.
- On July 18, 2026, Microsoft deployed a service-side mitigation which returns synchronization times and sync operations back to normal for new WSUS installations and rebuilds. After this date, newly installed or rebuilt WSUS servers should not encounter this issue.

Deleting a file from the Recycle Bin displays an internal filename in the dialog

When permanently deleting a single item from the Recycle Bin, the confirmation dialog displays the internal Recycle Bin filename (for example, $Rxxxxx.ext) instead of the original filename. The Recycle Bin itself correctly displays the original filename, and restoring the item also restores it using the original filename.
This issue occurs after installing the Windows security update released on June 9, 2026 (KB5094041).
Resolution: This issue was resolved by Windows updates released July 14, 2026 (KB5099444), and later. We recommend you install the latest update for your device as it contains important improvements and issue resolutions, including this one. If your organization has installed an update released on July 14, 2026, or later, you do not need to use a Known Issue Rollback (KIR) or a special Group Policy to resolve this issue.
