Windows Server 2025: Remote Desktop Freezes After February 2025 Update

Windows Server 2025 Users Face Remote Desktop Lockups Following February Patch
A recent security update for Windows Server 2025 is raising eyebrows across IT departments, with Microsoft's own advisory confirming that Remote Desktop sessions can suddenly freeze shortly after connection. The issue stems from the February 2025 Security Update (KB5051987) and appears to be affecting a range of deployments. If you rely on smooth RDP performance for managing your servers, brace yourself for a potential bout of digital déjà vu.
──────────────────────────────
Overview of the Situation
Microsoft’s official warning highlights that after installing the February 2025 update—and subsequent patches—on affected systems, users might find that their Remote Desktop sessions “freeze shortly after connection.” This isn’t your standard connectivity hiccup: when the glitch hits, keyboard and mouse inputs become entirely unresponsive, forcing users to disconnect and start their sessions afresh. Microsoft has yet to announce a timeline for a fix, implying that the underlying issue might be more complex than initially assumed.
Key points:
• The problematic patch is KB5051987, released on February 11, 2025.
• Remote Desktop sessions on Windows Server 2025 may lock up, rendering mouse and keyboard inputs unresponsive.
• Administrative guidance now pushes for the installation of the latest updates to mitigate the impact.
• Microsoft refrains from disclosing when a definitive fix for Windows Server 2025 will be available.
──────────────────────────────
Tracing the Patch History
Interestingly, Microsoft isn’t new to patch-induced anomalies. Earlier in the year, a similar glitch was observed in Windows 11 version 24H2, where UDP-based Remote Desktop sessions would disconnect after 65 seconds when attempting to connect to older Windows Server versions, such as Server 2016. That issue was rectified with the March 27, 2025 update (KB5053656). For enterprise deployments that had already installed KB5053656 or later, the current advisory explicitly states that no additional rollback measures or group policy tweaks are necessary.
Despite resolving the older Windows 11/Server 2016 connectivity hiccup with a rapid patch, it appears that Windows Server 2025’s remote desktop woes have proven to be a tougher nut to crack—leaving administrators waiting without clear guidance on a resolution rollout.
