Vista: unable to close windows using X button; MMC not working
Hi! I have a HP laptop with Windows Vista Home Premium. There seems to be a few problems on it:
1. I cannot open the Device Manager:
Microsoft Management Console
Failed to create an empty document
2. Some of the buttons on prompt windows are blank
3. I cannot close any windows using the red X button (ALT+F4 works). When the Aero theme is enabled the X button is clickable but nothing happens. When the Vista Basic theme is enabled, all the X buttons are greyed out and don't work either.
4. The context menu does not show when I right-click on an open window or application in the task bar.
I tried doing a system restore without luck and I cannot seem to find the cause or solution.
Any help would be appreciated.

Thanks! I ran a scan with Norton in safe mode, which didn't turn up anything. I'll give it another shot with anti-malware software.

Ok, I found some malware in safe mode and have removed it, but the problems still persist. I'm also getting erros about not having admin privileges even though I'm on an administrator account when trying to remove programs through the control panel.

Thanks! I do have a Vista DVD. Is there anything on that I can use to restore the system/ repair the group policies?

Sorry, missed that... Ran sfc and it seems to have fixed the problems as far as I can tell.
Just one more problem remains I think - I am trying to uninstall "Winamp Toolbar for Firefox" and everytime I attempt to uninstall I get this error message:
"You do not have sufficient access to uninstall Winamp Toolbar for Firefox. Please contact your system administrator."
I have tried uninstalling using a standard account with UAC on and also using an administrator account with UAC on and UAC off.
