I seem to have been victim of a virus: I no longer have Control Panel in Windows XP. Michael Coxon
Everything in Windows can be controlled using Group Policies, which enables companies with servers to lock down their users' PCs. Viruses can use the same settings in the Registry. If you remove the NoControlPanel Policy, the Control Panel should reappear. PC Tools explains how to edit the registry to do this. However, the Kelly's Korner website offers lots of tweaks and fixes to do this kind of thing simply by downloading and double-clicking a small reg file. Try running number 256, controlpanelrestrictionrestore.reg.
