About activation of Windows XP Retail.

Windows XP Store Retail version has been installed on a single computer at a given time, but it has been traveling from one configuration into another a lot. Each time it has been activated, first time over net, next ones over phone. After about tenth activation over phone with explanation of reasons for testings, I was doing activatons over net without any questions from microsoft.
