Title: Crucial Alert: Windows Server 2025 Security Update Causes Remote Desktop

Overview of the Issue

A recent security patch for Windows Server 2025, dated February 11, 2025 (KB5051987), has inadvertently disrupted Remote Desktop Protocol (RDP) connections, leading to significant user challenges.

Impact on System Operations

Following the February Patch Tuesday rollout, numerous reports have surfaced regarding RDP sessions freezing moments after initiation. This malfunction affects both Windows Server 2025 and Windows 11 version 24H2, causing unresponsive mouse and keyboard inputs and forcing a session restart.

Extent of Disruption

• Sessions hang either at the login stage or during active operations.
• Repeated reconnection attempts are necessary to maintain stability.
• Significant disruption for settings heavily reliant on remote access capabilities.

Current Resolutions and Workarounds

While a permanent fix for Windows Server 2025 is still in development, Microsoft has released a temporary patch for Windows 11 (KB5052093) on February 25, 2025, which offers partial relief. They have committed to solving this issue fully in an upcoming update, though a definitive release date remains unspecified.

In the meantime, users can mitigate the issue by adjusting Group Policy settings for RDP, specifically activating “Select network detection on the server” within Remote Desktop Session Host configurations.

Additional Complications and Remedies

• Intermittent disconnections up to 65 seconds observed with UDP connections from Windows 11 version 24H2 to older server versions.
• Peripheral issues with USB printers and network shares noted post earlier updates this year.

For these and other update-induced complications, Microsoft has implemented Known Issue Rollback (KIR) to quickly revert problematic changes on affected systems.

User and Community Feedback

The ongoing RDP issues have sparked considerable dialogue and frustration among IT administrators and end-users alike. Online community forums continue to highlight challenges, with some users even reverting to previous system versions temporarily, pending a stable solution from Microsoft.

For the most current information on upcoming fixes and updates, it is advised for organizations to regularly check official Microsoft release notes, especially those environments where RDP functionality is critical.
