The 3 key points not to miss
On January 13, 2026, Microsoft deployed an update known as Patch Tuesday, aimed at fixing more than a hundred security vulnerabilities. Although the goal was to improve the security and stability of Windows 11 and Windows Server systems, this update introduced a major problem for many professional users.
The KB5074109 update caused malfunctions in the Remote Desktop connection system. Users reported systematic failures during authentication, making access to cloud environments such as Windows 365 and Azure Virtual Desktop impossible.
Microsoft acknowledged this issue on its Windows Release Health dashboard. The problem seems to focus on specific builds, notably Windows 11 24H2 and 25H2, as well as several versions of Windows Server.
In response to these disruptions, Microsoft proposed temporary solutions. It is advised to download the classic Remote Desktop client for Windows or use the web version of the application through a browser. An out-of-cycle fix is currently in preparation and should be available shortly.
