said by Rexter:I'm not really sure I see a point to the "refresh" for this purpose. I installed it the first time. It accepted the key for install, but refused to activate. I then went through the install process again, while deleting the entire hard drive, clean install. This time it activated automattically. Basically, it does work just like Windows 7 Upgrade, except you have to enter the key to get it installed both times.
If you already did a 2nd install there is no need to refresh.
The refresh is what you do on an win 8 upgrade clean install instead of a double install.
