Emergency Windows 11 Updates Fix Shutdown And Remote Desktop Failures

[harlan4096]

Microsoft has issued emergency out-of-band updates for Microsoft Windows 11 after the latest security patches introduced two serious regressions. Affected systems were unable to shut down or hibernate correctly, and Remote Desktop sign-ins failed on certain configurations.

The issues appeared with Microsoft’s first Windows 11 updates released in 2026. Reports quickly surfaced from users who found that shutdown attempts would hang or fail entirely. Separately, Remote Desktop connections could no longer authenticate, preventing sign-ins to affected machines. Both problems were severe enough that Microsoft released fixes outside of the normal update schedule.

Microsoft has now published two out-of-band updates, KB5077744 and KB5077797, which are rolling out through Windows Update. Installing the updates restores normal shutdown behavior and resolves the Remote Desktop authentication failures.

The shutdown issue affects devices running Windows 11 version 23H2 with Secure Launch enabled. On these systems, shutdown and hibernation could fail after the January security updates were installed. The Remote Desktop problem has a broader scope, affecting Windows 11 version 25H2, Windows 10 22H2 ESU, and Windows Server 2025, according to Microsoft’s advisory.

Users who rely on Remote Desktop to access work or home systems were effectively locked out until the emergency patches became available. Microsoft has not provided a detailed explanation for how the issues passed testing, but confirmed that the fixes fully address the reported behavior.

The out-of-band updates are offered automatically via Windows Update. Devices configured to pause updates or managed through enterprise update policies may require manual approval or deployment before the fixes are applied.
