Overview
- Microsoft says a bug in Samsung's Galaxy Connect app caused C: drive access denials on certain Samsung PCs rather than Windows 11 update KB5079473.
- The company reports no evidence of Blue Screen errors or reboot loops linked to the March Patch Tuesday release.
- Microsoft removed Galaxy Connect from the Microsoft Store, and Samsung republished a stable previous version to stop new cases.
- Impacted hardware includes Galaxy Book 4 laptops and Samsung Desktop models on Windows 11 versions 24H2 and 25H2, with specific model numbers listed by Microsoft.
- Users can lose access to files and apps and may be unable to elevate privileges or collect logs, and Microsoft notes recovery options are limited and directs customers to Samsung support.
