For anyone interseted about how the product keys and activation is going to work here is how.
OEM computers now shipped with Windows 8 will no longer come with a COA sticker. The product key is now being injected into the BIOS and windows will automactically activate as soon as it is connected to the internet or you have the choice of calling up Microsoft to have it Activated manually. This will make it easy when you need to reinstall windows etc.
Q: What if I put another hard drive in and install windows then take it out and put it back into my other computer?
A: Microsoft have already thought a bout this. If you try and and installed windows using the same product key, activation will fail for both until one has that product key deleted. Heres how this works
Microsoft provides product keys to OEM>>>OEM inject the product key into the BIOS>>>>OEM then create a thing called a CBR(Computer build report)Which consists of hardware hash and logs this onto a online database>>> Customer then buys the computer>>>>Once connected to the internet it will retrieve the CBR to cross reference the product key and hardware hash to make sure it all matches.
