I recently lost the ability to use most of the after-market programs installed on my cpu. When i try to open them, they ask for serial numbers. However, they do not accept the serial numbers when I type them in. When I try to uninstall them, I noticed I do not have install/uninstall privileges. And most do not show up in add/remove hardware. I also lost access to my Outlook Express mailboxes. And my desktop looks screwy.
I have only one user account: "Administrator," but it seems I've lost my Administrator privileges. System Restore only goes back to the date it occurred.
Is there a way to get full admin access or at least make the cpu recognize the programs it shows on the desktop?
