Windows 7 UAC (user account control) won't open

Hi, I'm new here, but I hope someone can help me out.

The other day I had to access User Account Controls because I was having some problems with Itunes and when I tried to open the Configure User Account Controls panel, a blank window opened for about 10-20 seconds and then it closed on its own. This kept happening even after I had restarted the computer. Also, this is the only thing with which this happens. Everything else opens perfectly.

I've been looking around for a while now, in other forums and costumer support, and I couldn't find anyone with the same problem or any thread addresing it.

I have a Windows 7 Professional, 32bit and I was using the Administrator account when this happened (it is the only account in the computer).

Anyone had this problem before?

Any suggestions of what might be causing it/how to fix it?

Thanks beforehand for any information/help

1. Open User Accounts by clicking the Start button , clicking Control Panel, clicking User Accounts and Family Safety (or clicking User Accounts, if you are connected to a network domain), and then clicking User Accounts.
2. Click Turn User Account Control on or off. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Select the Use User Account Control (UAC) to help protect your computer check box to turn on UAC, or clear the check box to turn off UAC, (In your case you need to turn it off) and then click OK.

In order to turn off UAC I need to open the "Change User Account Control", which is the window that opens blank for 10-20 seconds and then closes on its own. This happens regardles from where I try to open it, be it from User Account

P.S.: In my previous post I called it "Configure User Account Control", my bad.

Hi hjonesMCT,

With Itunes it's not really a problem, it's an annoyance. Whenever I connect my Ipod it and open Itunes, it constantly keeps asking me to authorize my pc or else it will delete all of my apps. I authorize it and then it works fine until I try to synch it again. I looked it up in apple support and it said to turn off UAC, restart my pc, turn UAC back on, restart it again and it should solve the problem (amongst other possible solutions). I noticed the problem when I went to turn off UAC, because the window would pop up blank and then close on its on.
The only new thing I remember installing is an "AVG Internet Security 2011" trial version a few day ago. I haven't done any tweaking to the OS.
One more thing, the last time I opened the Change User Account Controls was back when i had just installed my Windows 7 professional to configure it (My laptop came with Vista, I switched to 7 a couple months after it came out) and have not opened it since.

Ran full anti-virus/anti-malware it detected a bunch of cookies and one or two currupted files. Cleaned everything up, still won't open.
