Or you could wait till tomorrow for the RC to be publicly released on the windows 7 website and download it there, you can also get a free product key from there.
Torrents take longer anyways, just download it legally from the Windows 7 website, put it on a DVD, install it, and activate it with the product key they give you before you start the download process.
Yeah http://www.microsoft.com/windows/windows-7/ of you click the customer preview program tomorrow afternoon it will let you download the RC, and give you a product key that will last until the middle of 2010
I believe it expires in June, but the RTM will be out long before then. Ive been running the RC for about a week now and I can guarantee that it is much much better then any of the beta's when it comes to speed and reliability.
