I have find out this >
Microsoft has moved to a new activation method in Windows 8 which means you won’t find the typical COA sticker (Certificate of Authenticity) on the back or bottom of your machine. Instead, the Windows license serial is part of the BIOS/UEFI, which Windows will automatically pull from the chip upon the first installation as well as subsequent reinstalls (i.e. when you perform a full Windows 8 recovery). If that, for whatever reason, doesn’t work, you can easily retrieve the product key from Windows 8 using Magical Jellybean’s Keyfinder.
so how does it work? If I am to reinstall windows, will it ask for me for the activation key? Is it in the my BIOS? If I install W7 on thiis machine and then choose to return to W8, how do I get the key?
