Denied all administrative privileges after permissions change
Hello all,
I've been lurking in this forum for years and generally found it more informative than other Windows 7 forums -- much more so than the Microsoft sponsored sites. Yesterday I was trying to solve a problem with massive replication/nesting of the “Application Data” folder and was reading this thread and found it so informative, I decided to join the forum. Little do I know I would need it two hours later.
In an effort to stop the replication, I changed permissions on C:\ (the above article suggested changing permission in “application data” but I decided to get cute) and now I’m locked out of all system files.
Here’s some of what I cannot do:
• Can’t run regedit.exe
• Can’t run cmd.exe as administrator
• Can’t even look inside C:\
• Can’t delete anything
I read this tutorial (Local Users and Groups) but can’t open it, I tried all three methods.
I logged-off and back on and it shows me as “administrator” but I can’t access anything. I don’t see “administrator” in any of the permission dialogue boxes. Even the owner of the computer is listed as “trusted installer”.
Here’s my User Account screen but I can’t do much but it does appear I can change the password. I haven’t done that yet because I don’t want to complicate things. Previously I did not have a password set.
I did System Restore (twice) but the lock-out remains. I was considering a re-install of the OS (I was considering doing that anyway to address some of the original replication issues) but I’m afraid the permissions would stay the same as they did on System Restore.
If I right-click C:\ and look at security, here’s what I get:
From here, I cannot click edit and when I click advanced, I get this:
I can’t Change Permissions. I can select the Effective Permissions tab but it doesn't seem I can change anything.
Here’s the usual denial I get:
But sometimes when I click, it just does nothing.
I’m fairly comfortable with Windows 7 but the convolutions of Permissions are over my head. It seems first I need to get administrative privileges back but I haven't been able to do that yet (I'm still reading those tutorials).
Needless to say, any help will be appreciated. I’m running Windows 7 Ultimate.
