Ok guys, heres the thing. Rather than trying to find all these ways round wga and winupdate and all that, why not just install a copy with a working genuine CD key? if you buy a pc it has a sticker with the CD key which enables download of microsoft products. Microsoft determines whether a cd key valid or not by the hardware u are using. one cd key that works on one machine, the same cd key will not work on another machines (unless its a vlk). Each CD key you can use on one computer if its retail. Therefore we can forget about retail keys. What we need is VLK keys. Volume license keys. Meanin one key can be used on many machines. However, there is a lmit and once the key has reached the limit of computers its meant for you cant use it no more.
The thing to do is go to a network computer running windows xp, ie, ur university, college, workplace. (not win net) then do a brute force check for VLK's. PM me for the program that searches. However, u need to get at least 20 keys as a vlk might be in use already u try the next one. PM me if you have any trouble. Im using a real cd key on my laptop. I get all the updates and can download everything from microsoft site. I even have the wga thing installed and it says i have a genuine copy of windows. Its great! lol good luck guys!!
