Windows 11 continues to grapple with a series of frustrating updates, and the latest round has left some Samsung users in a bind. Following the February update (KB5077181), a number of Samsung devices are reporting a disconcerting error: “C: is not accessible – Access denied.” This issue has been confirmed by Microsoft, particularly affecting models like the Galaxy Book 4.
Some Samsung devices cannot find their C: drives after the February Windows 11 update
As detailed on Microsoft’s “Windows 11, version 25H2 known issues and notifications” page, the problem arises when users attempt to access files, launch applications, or perform basic administrative tasks. The error message effectively locks users out of their C: drive, impacting essential programs such as Outlook and various Office applications. Moreover, users may find themselves unable to elevate privileges or uninstall updates due to persistent permission failures.
There are some user-suggested fixes, but they may be risky
While Microsoft has acknowledged the issue, it remains uncertain whether the root cause is linked to the Samsung Share application. In the meantime, a growing discussion on platforms like Reddit has surfaced, where users are sharing potential workarounds. One suggested method involves logging into an administrator account, adjusting the C: drive’s properties, and modifying security permissions to regain access.
However, these fixes come with their own set of risks. Users are advised to proceed with caution, as altering drive permissions can lead to further complications. For those wary of potential pitfalls, the safest route may be to uninstall the problematic update or simply wait for an official patch from Microsoft to resolve the issue.
