Hi Dimers !!
These keys have not been obtained via Upgrade Assistant.
I can provide the key only. You have to download the Windows ISO from Microsoft (MSDN) or Torrent (faster method).
I have used one of them and want to sell the rest 3. Interested dimers can contact me.
Method of Payment :-
For 3 keys : Bank Transfer
For 1 key : OxiCash / Bank Transfer
For any clarification, they can comment in this thread.
