Les mises à jour de septembre 2026 pour Windows Server 2019, 2022 et 2025 provoquent des pannes des services Bureau à distance (RDS).

Le post Windows Server : le patch de septembre 2026 casse les serveurs RDS a été publié sur IT-Connect.

Windows administrators report that the September 2026 cumulative updates can cause Remote Desktop Services (RDS) to hang or crash on Windows Server 2019, 2022, and 2025. Microsoft’s release notes separately confirm Remote Desktop problems in Windows Server 2016, including broken audio redirection, while the updates also address a critical RDS remote-code-execution flaw.

CompatTelRunner.exe is a Windows Compatibility Appraiser process. It runs diagnostic checks to determine whether a device’s hardware, drivers, and installed applications are compatible with upcoming Windows feature upgrades or cumulative updates. Microsoft has confirmed that the August 2026 security updates can cause recurring `0xc0000409` crashes in `CompatTelRunner.exe` on Windows Server 2016. The issue affects physical servers and virtual machines, including VMware and Azure deployments, but does not currently impair system functionality.

Microsoft will significantly tighten Windows Hardware Compatibility Program (WHCP) driver signing from March 2027. Drivers targeting Windows 11 25H2 or later and Windows Server 2025 or later will need validated Software Bill of Materials (SBOM) and Vulnerability Exploitability Exchange (VEX) files, while submissions will also need to target relatively modern hardware.
