Thinkpad T430s. It's a year old so I'm in the clear upon more detailed reading of the article. I usually do a clean install but when I bought this box it came installed with Win 7 and the discs I got were Win 8 only. Didn't come with a Win 7 serial. This is what I get for buying from a reseller on Amazon.
If you have Windows installed I think you can extract the license key from it (assuming Windows is genuine), then use it to do a clean install, or just save it for posterity in case the hard disk ever dies. As far as I know this is fine WRT Windows EULA.
no you cant - not in lenovo's case. The reason for this is that the keys for lenovo correspond to a very special Windows release that Microsoft specially bakes for Lenovo. You cannot use the keys on any other ISO.
This is also a big problem - you cant download these ISOs (unless some *rrentbay) and Lenovo does not give you CDs readily.
