Sometimes when I try to perform certain ACTIONS like replace files or delete them. It comes up with a box saying that I need Administrator permission to do so. I am the only person who uses this computer and my account type is set to administrator. It's the only account on the computer. How do I fix this? At the moment I'm trying to replace a .dll file in System32. Because I believe the other one is corrupt. This is only one instance.Sometimes, you need to take the ownership of the file. SEE here: http://www.winmatrix.com/forums/index.php?showtopic=13157That ownership tool seems like a virus or TROJAN.
I don't think I trust putting it in my registry. How long do you think we would be here if we gave advice like that ? ?

You should apologise to Broni.I give up....LOLit's CALLED UAC and new in vista...you can read about it here:

best not to turn it off, just accept the permissions...IMO

you should be able to use SFC (system file checker) to check that file
and the others...SFC(google it)Using, or not using UAC, and getting file/folder ownership are two different things. Quote from: Broni on December 01, 2008, 09:29:43 AM
