My wife complained her pretty desktop picture changed to a plain gray.When clicking >start >settings >there is no control panel listed. Also when right clicking on a open desktop space and "properties" the error message reads "This operation has been canceled due to restrictions on this computer. Please contact your system admin.." I have run Hijackthis and nothing shows up. Also a in depth scans with NOD32 and Spyware Doctor show the computer to be malware free. I did a repair over a installation and nothing changed. Suggestions?
