XP - Lost Control Panel + Admin Rights - Please Help

Hi - I have a home XP system and when I did a spyware scan a few months ago I lost my control panel and Administrator rights. I ran "Control userpasswords2," from the command line and it shows that I have administrator rights. But, when ever I try to remove or install a program the system says "access denied make sure the disk is full," or You do not have privileges contact your system administrator. I started in safe mode, created a new account, with full administrator privileges, but, that too did not work. By the way the control panel was not available in safe move. I even checked the registry for "noncontrolpanel," and could not find that entry. Any help or suggestions would be appreciated. Thanks... Ronnie

 

Thanks...I check and my system is clean. I manged to get the control panel back now I need to get administrator rights back. I created a new account with administrator rights but really don't want to have to reset the desktop and re enter registration numbers. Thanks.
