I don't see the defaults documented. Odd omission or not, read http://www.sevenforums.com/general-discussion/176036-how-remove-reset-all-security-files-folder-permissions.html and many other discussions.
Sounds like a great question to ask Microsoft.
I happened changed owner to my C:\ to Administrator, and I'm trying to change it back to how it normally should be, without reinstall my pc.
Can someone help to check on a normal Vista PC which fold sould be owned by Trustedinstaller and which should be SYSTEM? and is there any fold should be owned by Administraor?
