In early February, users of Samsung's Galaxy Book4 laptops reported storage issues, specifically error messages stating, "C: is not accessible," which locked them out of their primary drive. Investigations by Microsoft and Samsung identified the Galaxy Connect app, preinstalled on these devices, as the cause of the problem due to its interaction with Windows that revoked permissions. Reports of the issue surfaced before the February 2026 security update for Windows 11, which was initially suspected to be the trigger. Microsoft acknowledged the problem on its website about ten days prior to March 16, when it was marked as "externally resolved." To help affected users, Microsoft provided a recovery article and both companies removed the Galaxy Connect app from their stores, replacing it with an older version. Only users who experienced the issue need to take action to restore their systems.
