Although these licenses are intended for evaluation purposes, the great thing near them, unlike trial Microsoft software, they do non expire. Because the agreement under which the subscription is provided is a single license, none of the software should exist distributed outside of it. Fifty-fifty though it is $50,000 worth of licenses, information technology is for one person only to use and no one else. Unfortunately, regardless of the licensing terms, individuals still corruption the program, either giveaway product keys or resell them on auction sites. Microsoft licenses information technology in good faith that customers won't do so.

The person who sold it to you probably sold it to 10 other people. Somewhere forth the way, one of those persons might have installed it on a second system, activated information technology. Because it went past the 10 activation threshold, Microsoft detected that it was being abused and blocked the key from further use.
