Programs not opening

Hi

I have Vista Ultimate

this morning a new problem appeared, I cannot open operating system
programs, like UAC and Windows update.

When I click on the links a window opens for an instant then disappears.

I have Windows firewall, defender and AVG antivirus installed and running.

Any ideas on how to fix this?

thanks

Daniel

System Restore to yesterday.

Start by shutting down and restarting the PC - what does that do for you?

Rebooting, hard or soft makes no difference.
