Hi, this maybe a solution for some try it and see...
Well for me I could not, under user account (Administrator), delete a pre-installed backup folder for Vista, which i no longer required as I'd updated to Windows 7. It resided on a 50% partition of my only harddrive, taking up 5.5GB, which i wanted to free up. It was owned by SYSTEM, not TrustedInstaller. It required permission from SYSTEM to delete it. Folder had read only attribute, which i could not change either.
Administrator already had full permissions, but not ownership, which i proceeded to take from SYSTEM:
Properties/Security/Advanced/Owner/Edit/select name of Administrator account/check box: "Replace owner on subcontainers and objects"/ OK your way back out.
I confirmed Administrator now had ownership and full permissions, but i still could not remove read only attribute or delete the folder.
I then went to the "Effective Permissions" tab, which is basically a tool for checking a user or groups current permissions on an file/folder. You cannot type a username into the "Group or user name" box.
Press select/Enter the object name (type the administrator name) at blinking prompt/Click "Check Names"/should return the found profile, underlined, in the text box/click OK.
It reads in the current permissions and you now have a grayed out Administrator username under the Effective Permissions tab with all of it's profiles current permissions for that file/folder. This is read only, you cannot change any permissions here.
Once again i could see that Administrator had full permissions. However, when I OK'd out to the folder in Explorer and right clicked once again, i noticed the Administrator shield had disappeared from the right click context menu for "Delete" and "Rename"
I proceeded to delete the folder, with only the default "Are you sure you want to move the folder to the Recycle Bin?" message
On further investigation the shield has vanished for all files/folders on the right click context menu!
I can now do as I please, as it should be for someone savvy enough with a pc.
As long as you don't touch the TrustedInstaller owned stuff such as C:\Windows or Program Files & some SYSTEM owned files, you should be ok.
All I can summise, at the moment, is that using the Effective Permissions Tool somehow altered the Setup Administrator to act as the Hidden Administrator account.
Go figure?
