GoKawiilMicrosoft patches KB5127936 to fix Remote Desktop failures tied to Administrator protection
Microsoft has released the KB5127936 preview update to fix a bug that blocked non-admin users from connecting via Remote Desktop on systems with Administrator protection enabled. The issue, which produced error 0xC000000D, affected enterprise-managed Windows 11 24H2 devices after installing the KB5124010 preview update or later Windows updates. Admins who don't want to install the new preview update can instead disable Administrator protection via Intune or Group Policy as a temporary workaround.
GoKawiil's interpretation of the reporting above, not reported fact.
The bug could have disrupted IT operations at organizations that rely on Remote Desktop for managing enterprise devices, especially those that adopted Windows security baselines enforcing Administrator protection by default. This marks at least the second time in roughly a year that Microsoft has had to fix Remote Desktop connectivity problems introduced by its own updates, which may raise concerns among IT administrators about update testing before deployment.
- KB5127936 fixes Remote Desktop connection failures caused by Administrator protection on Windows 11 24H2 systems.
- The error (0xC000000D) mainly affected enterprise-managed remote hosts after installing KB5124010 or later updates.
- Admins can alternatively disable Administrator protection via Intune or Group Policy while waiting for the next Patch Tuesday update.
