you can easily generate the key by going to the microsoft vista homepage (click download)... all you need is a hotmail/MSN passport ...
you are only limited to 2 though.

I am a connect user, (got Office beta from there, pretty cool btw, recommend to download), let me get the newer vista... hopefully that solves my apparent incompatibility with winamp...everytime i install winamp, it failing to reboot due to a corrupted pxhlpa64.dll and i have to restore it to a point before i installed winamp...)
