Microsoft forced to issue emergency out of band updates for Windows 11 after latest security patches broke PC shutdowns and sign-ins

The latest OS updates for Windows 11 introduces two major bugs that caused issues with shutting down your PC or signing into your PC using Remote Desktop.

Microsoft's first update for Windows 11 in 2026 has already caused two major issues that saw users unable to fully shutdown their PCs or sign-in into a device when using Remote Desktop. These are two serious issues that were not spotted by Microsoft during testing, and are so severe that the company has now issued an emergency fix to address the problems.

This isn't the first time Microsoft's lack of quality control has impacted Windows 11 PCs in a major way. Being unable to shut down your PC due to a recent OS update is a huge oversight on Microsoft's part, but this is the latest in a long list of updates over the last year to cause a major issue like this.

The out of band updates, KB5077744 and KB5077797, are available now via Windows Update and is rolling out to everybody. Once installed, your PC should go back to being able to shut down successfully, and signing-in via Remote Desktop should work again.

UPDATED - www.neowin.netMicrosoft has also confirmed problems on classic Outlook as many users claim that the new Windows 11 25H2 and 24H2 update, KB5074109, made the app "completely unusable" as there are random hangs and freezes, unsaved email progresses, and more.
