I have heard that when connected to the net WinXP contacts a Microsoft server and exchanges data about your computer. During this time M$ can detect the number of copies of XP you may be running. And so, if you happen to be running the same version on more then one comp, or a warez version they can detect it. I know it is illegal to run one version on more then one comp unless you buy some kind of license. This is the only barrier keeping me from upgrading to any form of XP, so is it true or not?
