Microsoft has resolved an issue causing Remote Desktop sessions to freeze on Windows Server 2025 and Windows 11 24H2 devices. The initial fix was provided on February 25 with the KB5052093 optional update for Windows 11, followed by the KB5055523 Patch Tuesday cumulative update for Windows Server on April 8. Users of Windows Server 2025 who installed the February 2025 Security update (KB5051987) experienced freezing issues that rendered mouse and keyboard inputs unresponsive. Microsoft recommended installing the latest updates for improvements and resolutions.
Additionally, Microsoft implemented a Known Issue Rollback (KIR) to address Remote Desktop and RDS connection problems stemming from Windows 11 24H2 updates since January 2025, which caused UDP connection interruptions to RDS hosts on Windows Server 2016. A permanent solution has been included in the recent cumulative updates.
Microsoft also fixed a bug causing blue screen errors and installation issues on Windows Server 2025 systems with over 256 logical processors, included in updates since the KB5046617 cumulative update. However, users were warned of potential login issues with Windows Hello after the April 2025 security updates and that some Windows Server 2025 domain controllers may become unreachable after a restart.
