I am the administrator on my computer, yet I can't access the main customization options, such as power options, user accounts, system, personalization, or performance information. I've tried disconnecting from any internet since it may be a system administrator's settings from the network that might have been the problem, but I still couldn't. I just want to have access to the things that I SHOULD have access to. I am the only one with an account on this computer.
As a side note: This computer came loaded with Vista and just recently I loaded Windows 7 onto it. I was the administrator on Vista, but I don't know if something got messed up in the process of switching to Windows 7? Maybe?
