I have searched and am not sure. I have a valid Winows 7 x64 professional. To upgrade to Windows 7 x64 Ultimate , do I use my Retail copy (Never activated) of Ultimate and upgrade it or should I do a fresh/re-format install? Thanks for taking the time to read this
Its a Dell that came with Windows Pro 7 x64. I already purchased Windows 7 x64 Ultimate from MicroCenter ( OEM for US$199.00) I am wondering if I should just re format it or can I just upgrade it with the OEM version I bought? Thanks for replying
