I'm also wondering how they handle Windows 7 OEM SLP installs. They might ask for the code on the COA sticker. I don't see how they can kill a Windows 7 OEM SLP install. They don't activate online and the Product code is used on many many PC's. There is no actual product code embedded in the BIOS, only activation info for that manufacturer. The code on the COA sticker is a unique code only posted on that PC. It's also blocked from the online activation servers. Normal retail install media for Windows 7 will not read the SLIC table, its not coded to. You'll be prompted to enter a code. That's what the code on the COA sticker is for. Your forced to do a phone activation so Microsoft can confirm its not being used on another PC, that's my theory anyway. Any time I've used one I had to activate by phone the first time.
It's a totally different situation as far as Windows 8 goes. The Product codes are actually embedded in the BIOS and are unique to that PC. And the PC activates online. They could easily block your OEM key if they wanted.
