You came up with that message because for microsofts profit they had the disk assign its self to your specific computer. therefor every other computer it was put on to it registers as a trial version. You can do something illegal like search for a crack or serial gen and put it in there or you can just call the company. They will make you pay 200 or some dollars for the OS because the billions of dollars that microsoft makes just isnt enough they need all your money. This also poses as a draw back for places like schools now who cant use the same disk on thier network forcing the school to keep an old OS. Now when these start to malfunction ( as most microsoft products do that i have used) the school need to buy new OS. Spending thousands of dollars for individual systems. Sacrificing education for profit. That should be microsofts logo! ...sry for the microsoft rant...i couldnt help it
