Windows 10 Home Full-Retail license to Windows 10 PRO using MSDN Key
Hi
A question about license and activation. I bought several months ago a Windows 8.1 Home Full-Retail license that I had used until I've upgraded to Windows 10 on the day-one (29-7).
Since a couple of month I've a Msdn subscription from my business company so I've five Windows 10 Pro license keys at least to upgrade the Home edition installed.
My worry is:
1) May I upgrade to Pro from Home without a clean install?
2) May I come back to Home full-retail license from Pro license (Oem?) using the Windows 8.1 product key I've printed on the original package?
Thanks a lot.
