Windows Server 2025 freezing after February patch

Microsoft has issued a cautionary note regarding a problematic patch released in February that is affecting Remote Desktop sessions on Windows Server 2025. Users may encounter freezing issues shortly after establishing a connection, particularly following the installation of the February 2025 Security update (KB5051987) and subsequent updates.

Details of the Issue

The advisory from Microsoft states, “After installing the February 2025 Security update (KB5051987), released February 11, 2025, and later updates, on Windows Server 2025 devices, you might experience Remote Desktop sessions freezing shortly after connection.” During these instances, both mouse and keyboard inputs become unresponsive, necessitating a disconnect and reconnect to regain functionality.

As of now, Microsoft has not provided a timeline for when a resolution will be available, suggesting that the complexity of the issue may require more time to address.

Related Concerns with Windows 11

This is not the first time Microsoft has faced challenges with Remote Desktop functionality. A similar issue was reported with Windows 11 version 24H2, where UDP-based Remote Desktop sessions would disconnect after 65 seconds when connecting to Windows Server 2016 or earlier versions. This glitch emerged in January, but the situation escalated significantly following the March security update.

Fortunately, Microsoft has since resolved that particular issue with updates released on March 27, 2025 (KB5053656) and later. The company recommends users install the latest updates, as they include crucial improvements and fixes, including the resolution for the earlier disconnection problem.

For enterprise-managed devices that have already installed the March 27 update (KB5053656) or later, Microsoft assures that there is no need to implement a Known Issue Rollback (KIR) or a special Group Policy to rectify the disconnection issue.

When further inquiries were made regarding the current situation with Windows Server 2025, Microsoft indicated that there were no additional comments to provide at this time.
