Microsoft has confirmed that the Windows 11 January 2026 Update is causing at least three major issues, rolling out fixes for two bugs.

Microsoft has released Windows 10 emergency update KB5077796 to fix Remote Desktop sign-in failures caused by recent Patch Tuesday updates.

The Windows App is Microsoft's one-stop shop for everything Windows launched via a rebranding exercise in 2024. According to Microsoft at the time, it "serves as your secure gateway to connect to Windows across Windows 365, Azure Virtual Desktop, Remote Desktop, Remote Desktop Services, Microsoft Dev Box, and more." Until, of course, it doesn't.

Windows 11 KB5074109 causes a black screen on some PCs, including those with an Nvidia GPU, and also freezes Outlook if you use POP.

Windows 11 Patch Tuesday updates for 24H2 and 25H2 reportedly break classic Outlook, causing freezes, hangs, and lost email drafts.

The Windows updates from the January Patch Day are causing connection issues with Windows 365 and Azure Virtual Desktop.
