Product Key for activation

I have installed version 7077. Where can I obtain the product key?

You can still get Beta keys from Microsoft's site.. ;) Windows 7 Beta Customer Preview Program

These keys will work for Windows 7 Ultimate only, so make sure you pick Ultimate from the list of different versions when you install... ;) The RC keys will be issued once the RC is officially released from Microsoft..

Thank you. I have activated successfully.
