If you have a Windows 10 Pro license, that should be valid for Windows 11, too, shouldn't it ?
The upgrade from Home to Pro should be simple. It is something like an enablement package, I believe.
When in Windows 11 Home, go to Change Product Key and enter the Windows 10 Pro key. That should be it. The upgrade should begin.
Hi Suat,
Yes it would Suat. You do not need to change to Pro on W10 first. As long as the device itself was Activated at some point with Pro, the generic key only enables the change of window versions. W11 would detect the previous Activation of Pro as it does in a total clean install.
If for example, the device was "Never Activated" with Pro, changing versions would result in an non-activated device.
The laptop that I upgraded to Pro, can switch back and forth between Home & Pro, it remains Activated in either as it is now licensed for both. Activation is tied into the Hardware ID now on MS servers. Nothing has changed here with W11.
Granted, there was a verify issue with total clean install of W11, MS fixed back in build 22000.65.
Regards,
