This is an interesting problem.
Customer brought in a Dell 4600 running XP SP2 Home with Win Antivirus Pro 2007 on it, along with other goodies, viruses, spyware, adware. I cleaned it, did a repair install, put in Webroot Spysweeper and Desktop Firewall and AVG antivirus. I think I got most of it, but I still cant get to the control panel or the Display Properties (the malware took over the desktop with its warning message).
Ive gone into the administrative userid in safe mode but still when I try to access the control panel or other major functions, I get: This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.
This is covered by Microsoft here:
But that doesnt work if every userid is locked out. I cant get to the User Configurations to change the permissions. How do we get out of this?
