I have a retail Upgrade of Windows 7 64 bit and a full license of Windows Vista that I used to install Windows 7 by. I have the Windows 10 free upgrade icon and will be able to get it but I will probably by building a new system in August or September after the new Intel CPU's come out. Does anyone know how this will work? Will I be able to do a fresh install of Windows 10 when I build a new system?
