Windows 11 March Update Gets Emergency Patch for Microsoft Sign-In Issues
Microsoft has released the KB5085516 out-of-band (OOB) update to address sign-in issues caused by the Windows 11 March update on certain applications. These issues included sign-in failures in the free version of Microsoft Teams, OneDrive, Microsoft Edge, Excel, Word, and Microsoft 365 Copilot. In Windows 11 versions 24H2 and 25H2 with the March update KB5079473, OS Build 26100.8037, users experienced problems when trying to sign in to their Microsoft accounts. Now, the company is distributing the OOB update for OS Builds 26200.8039 and 26100.8039. Microsoft claims there are no known issues with this OOB update, suggesting that most concerns have been resolved and users can safely apply the update again.
The problem originally occurred when a device entered a specific network connectivity state that the Windows 11 March update did not handle well, causing some Microsoft applications to mistakenly identify the device as offline. Initially, Microsoft advised users to simply restart their devices to fix the issue, but the connectivity state where Microsoft accounts wouldn't sign in would often return. There was a significant chance that the device might revert to this specific networking state, resulting in repeated sign-in errors. However, now this has been resolved with the KB5085516 OOB update, which fixes networking states, so your device can continue running smoothly.
