The senior editor at the blog Windows Central decries two serious Windows 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."
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... 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... 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...
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.
"The out of band updates, KB5077744 and KB5077797, are available now via Windows Update and is rolling out to everybody," they write. "Once installed, your PC should go back to being able to shut down successfully, and signing-in via Remote Desktop should work again."
Microsoft has also officially acknowledged a third bug which crashes Outlook Classic when using POP accounts, according to the blog Windows Latest, which adds that that bug has not yet been fixed.
They've also identified other minor bugs, including "a black screen problem in Windows 11 KB5074109... either due to the update itself or some compatibility issues with GPU drivers."
After you install the January 2026 Update, Windows triggers random black screens where the desktop freezes for a second or two, the display goes black, then everything comes back. I can't pinpoint any specific configuration, but I can confirm the black screen issue has been observed on a small subset of PCs with both Nvidia and AMD GPUs.
