Windows 7 - Administrative powers in W7

Hi I'm running a personal administrator account and everytime that I try to unzip files to the main drive it says it always fails. But when I unzip it into the desktop the unzip works. So what I do is unzip my files to the desktop and then copy paste then into programfiles so just it'll work. Hassle.

This maybe so because of the protection that Windows 7 applied on the main drive.

Question:

1.) How do you turn off that security feature by windows 7 so I can directly unzip files into the main drive C:\

What unzipper are you you using? Yes, you will need administrator privileges.

I am using winrar, so how do you enable winrar to permanently have administrator rights on?

You can either right-click on winrar and choose "run as administrator" or create a short-cut, go to the compatibility properties and choose "run as administrator". The former allows you to run the program with elevated privileges once, the latter - always.
