Windows 10 Portability
Have a Windows 8.1 Pro product key Retail,if I Upgrade that to Windows 10 Pro on the same computer,obviously, that will probably not a problem .
Since windows 10 does NOT utilize product keys any more and using digital entitlements, what if I need to install Windows 10 in another PC in the future.?
Can I still Reinstall Windows 8.1 Pro using the same Product key, after the 1 month grace period for allowing users to Revert back?
