Our IT dept has delivered to us several new laptops with WinXP Pro on them. Unfortunately they have disabled the WinXP interface and made it look like Windows 2000. Normally this would be an easy thing to undo, just a right-click on the Start button, then properties, then select "Start Menu". On these laptops only the "Class Start Menu" option is there, not the other option.

Anyone know how to enable this again? It it must be a registry setting, but I am not getting any matches on Google for it.
