Windows 11 KB5085516 is rolling out on 25H2 or 24H2. Microsoft told Windows Latest that it’s an out-of-band update meant to address major issues affecting Microsoft account internet connectivity in some apps after the March 2026 Update. The bug broke Microsoft account sign-in in apps, such as Teams, Office apps, OneDrive, and Outlook.
Today’s emergency update shows up as “2026-03 Update (KB5085516) (26200.8039),” and it doesn’t appear to download automatically.
I asked Microsoft if it’s an automatic, forced release, but I’m told that it’s an optional out-of-band patch, and anybody with Microsoft account internet issues in these apps can download it.
This emergency update bumps Windows 11 25H2 to Build 26200.8039, while 24H2 gets Build 26100.8039. It takes approximately five minutes to download, and another five to seven minutes to finish applying the patch.
