Hi
I think this may help with your problem.
Windows 7 has it's own ideas about what logged in as administrator means.
If you really want to do something as an Admin. you have to go through this process.
How to Enable the Administrator Account
1. Open the command prompt with elevated privileges.
Do this by clicking the Start orb, All Programs, Accessories, right-click Command Prompt and then select Run as administrator.
2. Type: net user administrator /active:yes and then press Enter.
You will now have two login options your usual one and Administrator.
To get back to not having this option, do the whole thing again and type in...
net user administrator /active:no
