Windows License Activation
From MobileRobots Research and Academic Customer Support
How do I activate Windows XP?
Microsoft requires that you register or activate recent versions of Windows XP Pro. We do not activate Windows before shipping the robot, you must do so. See http://support.microsoft.com/kb/307890 for instructions, including how to activate by telephone, if you cannot or do not wish to attach the robot's computer to a network with Internet access.
Activation is not necessary for Windows XP Embedded (which has superceded XP Pro as our Windows OS).
