Windows 7: NTFS Security Permissions

27 Aug 2011   #1

Win7 Premium
NTFS Security Permissions

I was screwing around with the permissions in Win 7 Premium, C:\Windows\winsxs and I now have them in a mess! System Restore wont work. Trying to rest the permissions with icals.

From an elevated command prompt I did this:
C:\Windows\winsxs>icacls * /T /Q /C /RESET

After running awhile I got this message:
successfully processed 73649 files; Failed processing 0 files

But nothing was changed?

Would someone please explain what it is I'm doing wrong?

You changed permissions of a highly sensitive portion of the system, WinSxS is Windows. That is what you did wrong. There is no "RESET" once you make a change, the "RESET" command of icacls does not do a reset like you are thinking it does. Lets this be a lesson, DO NOT DO IT AGAIN. Reinstall Windows.

Leave NTFS permissions alone from now on, do not even look at it.
