Windows 11 how to fix C drive problems

Last week, Microsoft acknowledged a bug in Windows 11 that exhibited abnormal behavior in some Samsung computers after recent updates. Affected systems had an inaccessible C drive, and were unable to run many common tasks. Soon, the company issued a statement and explained that Samsung's software affects certain models of its laptops.

Now, the company has published a special guide explaining how to fix affected systems.

First, you should uninstall Samsung Galaxy Connect and/or Samsung Continuity Service from Settings > Apps > Installed Apps. Then, restart your computer and temporarily add permissions to the C: drive.

Right-click on drive C and select Properties.
Go to Security > Advanced.
In the new window, click Change next to Owners.
Type Everyone and click OK.

The next step is to add a temporary permission to the C drive:

Right-click on drive C and select Properties.
Go to Security > Advanced and click Edit.
Click Add and type Everyone.
If prompted, click Yes. If Windows 11 displays multiple warning prompts, press Alt + C.

Now, it's time to restore the original permissions:

Open Notepad and paste the following:

icacls c:\ /grant BUILTIN\Administrators:(OI)(CI)(F)
icacls c:\ /grant “NT AUTHORITY\SYSTEM:(OI)(CI)(F)”
icacls c:\ /grant BUILTIN\Users:(OI)(CI)(RX)
icacls c:\ /grant “NT AUTHORITY\Authenticated Users:(OI)(CI)(IO)(M)”
icacls c:\ /grant “NT AUTHORITY\Authenticated Users:(AD)”
icacls c:\ /setowner “NT Service\TrustedInstaller”
icacls c:\ /remove everyone
pause

Save the file as RestoreAccess.txt, then change its extension to bat – RestoreAccess.bat.

Right-click on the new file and select Run as administrator.
Restart your computer.

Now, drive C and all the problematic functions will work as expected. If the problems persist or if you do not want to do the suggested steps yourself, Microsoft suggests contacting Samsung support.
