Microsoft fixt Remote-Desktop-Probleme

Microsoft has solved a problem with Windows updates from the beginning of the year that caused Windows 11 24H2 and Windows Server 2025 to have problems with RDP sessions. The sessions simply froze as a result. Microsoft has now announced that the April updates will correct this.

Microsoft has now updated the entry on the problem in the Windows Release Health Notes for Windows Server 2025. "After installing the February security update (KB5051987) and newer updates on Windows Server 2025 devices, remote desktop sessions may freeze shortly after connecting. When this occurs, the mouse and keyboard in the session stop responding, forcing users to disconnect and reconnect," Microsoft's developers write.

April security updates as a solution

"The problem fixes KB5055523", i.e. the security update from April, the company now explains. "We recommend installing the latest update on your devices as it contains important improvements and fixes."

In the Windows Release Health Notes for Windows 11 24H2, Microsoft has also set the date for the fix for this week in the overview, but the article text differs slightly from that for Windows Server 2025. "After installing the Windows Update Preview from January 2025 and subsequent updates", the problem may occur in the desktop operating system. Microsoft then states that the update preview from the end of February (KB5052093) had already fixed the problem, with a date of the end of March.

Admins who observe RDP problems should therefore install the latest updates from April if in doubt. The freezing RDP sessions should then no longer occur.

In the recent past, Microsoft has repeatedly let updates slip through that cause widespread problems after release. Earlier this week, for example, Microsoft released updated update packages for Windows 10 22H2, 21H2 and Windows Server 2022. They correct an error that could occur since the installation of the April security updates: "After installing this update, you may see the following error message on the Windows Update settings page: 0x80070643 – ERROR_INSTALL_FAILURE. This error message is incorrect and does not affect update or device functionality," Microsoft explained. This was triggered by the KB5057588 update for the Windows Recovery environment.
