KB5085518 hotpatch fixes apps sign-in issues for Windows 11 25H2 and 24H2 enterprise users

Hotpatch update KB5085518 solves the issues with signing into apps like Microsoft Teams and OneDrive for eligible Windows 11 25H2 and 24H versions

Microsoft continues to release emergency OOB (out-of-band) updates to resolve issues caused by recent patches. After last week’s KB5084897 update that fixed Bluetooth connectivity issues in Windows 11, Microsoft has now released the KB5085518 hotpatch update for Windows 11 versions 25H2 and 24H2, which deals with sign-in problems with personal Microsoft accounts.

The March Patch Tuesday update (KB5079473) for Windows 11 25H2 and 24H2 caused problems with apps such as Microsoft Teams and OneDrive, where users couldn’t sign in using a personal Microsoft account. Even with a working Internet connection, a “no Internet” error would appear. This update deals with these issues.

Here’s the official changelog:

"[Microsoft account sign in] Fixed: After you install the Windows update released on or after March 10, 2026, some users might experience an issue signing in to apps with a Microsoft account. Even when the device has a working Internet connection, a “no Internet” error appears during sign in and prevents access to Microsoft services and apps such as Microsoft Teams Free and OneDrive."

This is a hotpatch update, meaning it’s arriving mainly to eligible Windows 11 Enterprise users (including Enterprise LTSC 2024). Microsoft released this exact same fix for regular Windows 11 versions just two days ago. The update will arrive and install automatically on eligible systems without the need for a restart.

Microsoft hasn’t listed any known issues caused by this update. However, Microsoft is having a turbulent period with recent Windows 11 releases, so that may change soon.
