Last week, several users reported a strange issue on certain Windows 11 laptops made by Samsung. After installing recent updates, affected systems started behaving abnormally. The biggest problem was that drive C became inaccessible, which caused many basic Windows features and apps to stop working.
The issue quickly caught attention because drive C is the main system drive on most Windows PCs. When it stops working properly, users cannot open files, launch programs, or perform basic tasks.
We had earlier reported about this problem when users started noticing the issue after installing recent Windows updates. Now, Microsoft has finally explained what actually caused the problem and has also published a guide to fix affected systems.
Microsoft acknowledged the bug shortly after users started reporting it. According to the company, the problem was not directly caused by Windows itself.
Instead, Microsoft says that certain Samsung software components were interfering with Windows permissions on some laptop models. Two programs were identified as the main cause:
- Samsung Galaxy Connect
- Samsung Continuity Service
These services appear to modify system permissions, which eventually caused Windows to lose access to the main system drive after the update. This is why the issue was mostly limited to specific Samsung laptop models instead of affecting all Windows PCs.
Microsoft has now released a detailed support guide explaining how users can fix the problem. The first step is to remove the Samsung software that caused the conflict.
Users need to open Settings > Apps > Installed apps and uninstall:
- Samsung Galaxy Connect
- Samsung Continuity Service
After uninstalling these apps, users should restart the computer.
After restarting the system, Microsoft says users must temporarily change permissions for drive C.
The process includes:
- Right clicking drive C and opening Properties
- Going to Security > Advanced
- Changing the owner to Everyone
- Adding temporary access permissions
These steps allow Windows to regain access to the system drive so that the system can function normally again.
Once temporary access is granted, Microsoft recommends restoring the original security permissions.
To do this, users must create a small batch file that resets the default permissions for drive C. The commands restore access for system accounts, such as:
- Administrators
- SYSTEM
- Authenticated Users
The script also removes the temporary Everyone permission that was added earlier.
After running the script with Run as Administrator, users must restart the PC. In most cases, this should restore full functionality and allow Windows features to work normally again.
Microsoft says that if the problem continues even after following the guide, users should contact Samsung support for further help.
