How come When I redownload version of Windows7 it keeps giving new serial?I am just curius hehe :pI dunno if I will be able to reply toomarow

Lukasz - The Microsoft web site picks a product key at random from a list when you download it. There are a fixed number of keys available and you'll find, if you hit the refresh button, it will pull up a different one. It doesn't generate a unique key every time.

I understand :)
