I bought one of these laptops two months ago. It has been working just fine. Today Microsoft told me that the license is not valid. It has a valid certificate of authenticity on the back but does not have a second "refurbished" CoA. When I look at the internal System Properties/General tab it says "XP Corporate" which means it was covered under a mass/site license which can not be transferred or sold. I will probably have to buy a fresh copy of XP ($100) and re-install.
Before I made the order I checked to see that the advertisement specified "Genuine Windows XP". I also checked the CoA when it arrived. When the Microsoft updater offered to run "Genuine Advantage" to check the authenticity I confidently thought "sure, go right ahead."
