So I just reinstalled vista home premium that came preinstalled on my laptop. I used a OEM Vista 32bit dvd and the OEM license that is printed on the side of the laptop, and guess what happens? The key is not valid and MS says I need to buy Vista. Jesus. Gotta call them up and hopefully get this resolved. The fuck is the deal here, I guess MS is now rejecting their own keys? Edit- just googled this, and found tons of others with the same problem. The key printed on the laptop will not pass validation.
