I just made a VHD of Windows 10 and it is running fine but needs Activation. I spent about an hour on the phone with Microsoft - no help This Win 10 was updated from Windows 7 but I do not have the key for Windows 7 anymore. HELP!! I used disk2vhd to make a VHD from my Windows that was activated.
Best way do as DAZ Loader and Install Windows 7 Pro, that it and then upgrade it.. Should be ok! ATGPUD2003
I think that if you update from Windows 7 to Windows 10, you don't need an activation code. I updated my Windows 7 to 10 and all goes ok!
