It is better if you fully describe your problem, or concern, using the body of the message rather than the subject line.
What is your concern? No one owns the C: drive.
You post is not clear.

Practically is very difficult fully restore permissions in Vista - a big obstacle are very subtle permissions.Yes of of course there are commands takeown,icacls to do it - with ownership shouldn't be any problems but with permissions -yes.See for example this thread:
The Application Failed to Initialize properly (0xc0000022) Click Ok to Terminate the

I've tried restore permissions by using command icacls -although my scripts theoretically are fully correct practically fail on C:\Windows. When script meet some file which is busy -system refuse changing permissions for this file -returns error "access denied" although you are already the owner of this file - interesting:in this situation there is no problem to change permissions for this file by using classic method:Take Ownership of file
Folder Permissions

But what important:if this kind of script meet error and can't change permissions for any file -all operation are stopped and don't work later although sometimes can return "success" but really there is no any success.Untill now I thinking (without any destination) how to fully restore permissions but untill now I don't know resolve.

If you have any trouble with permissions you should describe your problem - there is also tool Process Monitor which use to detect trouble with permissions
