This install is a legal copy but the honesty of your installer is in question ..From what I have seen here in Dallas they are using a microsoft technet mod to make these installs valid. In other words , you get a valid oem of windows 7 but these system builders are doing it illegally and claiming its legal .I guess it all depends on you ethics. If Microsoft decides to stop this flagrant use of the msdn technet mod installs you may have to worry where that leaves you..
