Install windows starter or premium using a default key or slp key (do not activate). Run down to walmart, buy the anytime upgrade key and install it/activate it. I don't know if it will work but it should. Another option is install and "activate" with DAZ's loader, use the anytime upgrade, uninstall Daz's loader. One of these options should get you activated pretty easily with a genuine key for less than an actual upgrade key and less hassle than the double install method of standard upgrade keys.
