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

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.

Here's the changelog for the out of band updates:

• Connection and authentication failures in remote connection applications: This issue affects multiple platforms including Windows 11, version 25H2; Windows 10, version 22H2 ESU; and Windows Server 2025. See the bottom of this message for the complete list of affected products.
• Devices with Secure Launch might fail to shut down or hibernate: This issue only affects Windows 11, version 23H2.

Other issues that have cropped up in Windows 11 in the last year include a bug that caused Task Manager to fail to close when the user exited the application, causing system resources to lock up after a prolonged period of time if the user had opened and closed Task Manager multiple times in a session.

Another update caused saw File Explorer flashbang users with a white screen when opening it in dark mode, which appeared in an update that was supposed to improve dark mode on Windows 11.

There was also an update that somehow broken the Windows Recovery Environment in a way that made it impossible to process through the recovery options to actually recover your PC. These sort of bugs appear to be cropping up into the product via Windows Updates all the time now, even with the company supposedly testing every update with Insiders first.

For whatever reason, the Windows Insider Program doesn't appear to be working anymore, as severe bugs are somehow making it into shipping versions of the OS. Microsoft really needs to address these quality control issues if it wants to help improve Windows 11's overall image, which is currently in the gutter.
