Question

"I accidentally added a 'Deny All' permissions rule to my C: drive on Windows. I need help resetting my drive permissions back to default."

Answer 1

Just checking with you, how are you proceeding with this problem.

Answer 2

Please follow these steps carefully, this should restore all defaults permissions on the C drive.

Click your Start button, then just type cmd and on the resulting list, right click Command Prompt and select 'Run as Administrator'.

Run these commands one at a time and press Enter after each command.

icacls c:\ /grant *S-1-5-32-544:(OI)(CI)(F)

icacls c:\ /grant *S-1-5-18:(OI)(CI)(F)

icacls c:\ /grant *S-1-5-32-545:(OI)(CI)(RX)

icacls c:\ /grant *S-1-5-11:(OI)(CI)(IO)(M)

icacls c:\ /grant *S-1-5-11:(AD)

icacls c:\ /setowner *S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464

When that command completes, close Command Prompt and restart (not shut down) your PC to apply the changes.
