Not mine. I have mine from a Technet account and Connect. Both have different sets of keys. The only keys I have ever seen, on either site, one set of keys. The premium is certainly available for download, but no keys for that edition were provided (to me, anyway). Browsing the Technet forums, it has been stated there that the Ultimate keys should work with the Home premium.
They are all he same keys on connect, to all subscribers, so I have PM'd one of my first (32Bit) to you Biffo, to see if it compares.
Ok, Joe, I should be able to install the 32 bit in about 2 hours from now. , Ill post again after that and let you know if the keys worked for me.
Ok. Downloaded and installed. The Ultimate keys would not work.
So the bad news. i rang Microsoft local and it seems that the connect account (ecosystem) ,has been hacked and the access code to the account has been widely broadcast on the web. They have currently stopped the keys for the premium, whilst they close the hole. The ultimate keys are still available, as they were on the Public release, but will not activate premium.
So, for the moment, best you go with the Ultimate, which is much more satisfactory anyway.
