Microsoft has officially acknowledged on the Windows release health dashboard that the Windows Server Update Services (WSUS) is currently facing a performance degradation problem. This issue has led to notably slower synchronization speeds and, in some cases, timeouts for enterprise customers across all supported Windows client and server editions. The situation reached its peak around July 13 and continued through the weekend, causing considerable inconvenience for IT administrators.

Microsoft clarified that the root cause of the problem lies in an irregularity within a specific update version in the storage layer. This irregularity has hindered users from deploying Windows updates through WSUS and Configuration Manager. At present, Microsoft is diligently working on a solution, but unfortunately, no interim workaround is available.

While manual updates are still operational, they are not a feasible option for enterprises that manage a vast number of devices. It's worth mentioning that Microsoft had already announced in September 2024 that it would cease developing new features for WSUS in the future. This suggests that the service may be gradually phased out, and Microsoft has advised enterprises to consider transitioning to more sophisticated update management tools at the earliest opportunity.
