Windows Product Activation (WPA) on Windows XP

One new feature in Windows XP that has caused great concern is Windows Product Activation (WPA). There are a great many rumors, and much misinformation, from which you might be led to think that WPA is going to call Microsoft every day and say just what you are doing with your computer; that, if you make any changes at all to your computer hardware, the machine will be instantly disabled; and that WPA is a sneaky way for Microsoft to store personal information about you or your computer, or to begin charging you a monthly fee for your continued use of Windows XP. In fact, all of these rumors are false. WPA is a fairly easy-going check when Windows boots, confirming that it is still installed on the same computer as last time it checked. That’s all. But the rampant misinformation is understandable, because it is hard for the general consumer to find a simple yet comprehensive explanation of just what WPA is. This page tries to fill that gap by explaining WPA in a straightforward, detailed way — and to show that it will be a lot less trouble to most people than many have feared.
