On September 11, 2026, Microsoft updated the Windows Health Dashboard, confirming that after installing the September security update KB5124008, failures occurred in the Remote Desktop Services (RDS) for Windows 10/11 and Windows Server series. The failures manifest as interruptions after a few minutes of connection, login failures, getting stuck on the configuration interface, and potential unresponsiveness of tools such as the Microsoft Management Console (MMC). The impact covers client versions (e.g., Win11 26H1 to Win10 LTSC 2016) and server versions (from Server 2012 to 2025). Microsoft's suggested temporary solution is to stop and restart the affected virtual machines, and no official fix patch has been released yet.
