I've seen many websites that sell seemingly 100% legit "branded" OEM Windows 7 (mostly Dell). They come with the original OEM installation disc, COA and CD key. They usually cost $60-$80 and are said to activate on any computer, without the mentioning of SLIC bios at all. I'd like to know how is this possible? I thought the OEM cdkey's will only work if the bios has been modded with SLIC 2.1?
