Ok father-in-laws pc is playing up again. There is no Control Panel option and when you right click on desktop and click properties it wont let you do it. This is the msg the pc gives. "this operation has been cacelled due to restrictions in effect on this computer. Please contact your system administrator." Well he alway has been administrator and always been able to use control panel and other stuff before so whats happened? also if you click his username with the avatar in the start menu wont let you do that either. :(
in the run box, press enter and let system file checker find and replace missing / corrupt file in windows and explorer.This will take awhile to complete and you may be asked for the CD to be in the drive if windows is not preinstalled on the hard drive.
