TrustedInstaller


 * TrustedInstaller**

Who is TrustedInstaller and why does he/she own all those files on your Windows system?
 * Deleting files protected by TrustedInstaller**

You thought that because you're the administrator, you would own the system files and folders by default, didn't you? But if you should ever need to delete one, you might discover that you don't have permission to perform the action and/or be told that "You need authorization from TrustedInstaller in order to perform this action." What is wrong with that? Well, you'll need to [|take ownership of that file away from the TrustedInstaller process] before you can do what you want to do. :- []

Be careful, though, when you're messing with files owned by TrustedInstaller. There's a reason Windows didn't make you the owner; so be sure you really know what the file does and are sure you don't need it before you remove it.
