So my hp laptop came with oem licensed win 8.I had to format and install windows 7? How do i get the OEM: DM key ?I tried someof the methods in a sticky like the DM dumper but i end up getting the prod key of the currently installed pirated win 7 If i get the OEM: DM then SKU from it and download and install correct win 8 version will it get activated ? I am sure it was single language and not pro.So is it possible that it was CORE SL or are there any other possibilities
