Windows 10: How to replace the unactivated Windows 10PRO version with the Windows 10Home version

I have acquired a used HP computer which has an unactivated version of Windows10PRO installed. I got it to replace a device that had Windows 10 Home installed. I would like to replace the PRO version with the Home version on the new device. How can I do that??

Convert a Windows 8pro product key to a Windows 10pro produkt key

Hello Karthicka_R

thank you for your reply.

But as i wrote in my question: without any new installation.

• I have a valid installation of Windows 10home
• I can upgrade this to Windows 10pro but i have to pay it, i don't want to pay anything, because
• I have a valid Windows 8pro license key which i can upgrade to Windows 8.1pro and then to Windows 10pro, but i don't want install all new on my PC which is running Windows 10home.
  
• I want to get a Windows 10pro product key for my Windows 8pro product key and enter them in my Windows 10home in the 'Change Product Key Dialog' to bring my Windows 10home to Windows 10pro without any new installation.
• I can't believe that i can only upgrade my for an update to Windows 10pro valid product key only with a new installation.

Thanks for any answers.

Kind regards

Andre

 

Which version of windows?

That's what I'd suggest. As long as you use a legit key (& no cracks) you can get the ISOs anywhere (MS, a friend, etc)

 

Differences among windows 10 versions

I've seen verities of versions have released by Microsoft for windows 10. And those versions have its own specifications. Such as 10EU, 10Pro, 10Home, and some have windows media player, and the others haven't, and some versions can't stop automatic updates. So
that it is not easy choose better one. If there is a easy way to find differences, it'll be much better.
