I get the following error when trying to select "Windows Updates" on the desktop or setting the display settigns and control panel is gone.
"This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."

I am running Windows XP Home with SP2.

Here is my HiJackThis log, I am thinking it is something to do with the Dell software running on this machine.
