I recently bought a new Acer laptop, that had Windows 10 Home preinstalled. Since I still had a Windows 8 Pro key, I wanted to upgrade that to 10 Pro.

What I did so far:

  • Install Windows 8.1 using a generic key (as the installer didn't accept the Win8 key)

  • Enter the Windows 8 key and activate license

  • Using MediaCreationTool I created a bootable Windows 10 USB drive

  • As suggested here I created PID.txt inside the Sources folder, that contains my original Windows 8 key I used to activate 8.1

  • When booting from the USB drive and choosing to upgrade Windows, I get the following notice:

    Compatibility report

    The computer started using WIndows installation media. Remove the installation media and restart your computer so that Windows starts normally. Then, insert the installation media and restart the upgrade.

  • However, when restarting the upgrade after booting Windows, it wants to install Windows 10 Home

So what else can I try, to upgrade to 10 Pro?

You can upgrade to Windows 10 Pro from Windows 10 Home using a Windows 7 or 8/8.1 Pro key.

First you need to upgrade to Windows 10 Home. Then Go to Settings > Update & Security > Activation > Change Product Key, then type VK7JG-NPHTM-C97JM-9MPGT-3V66T as the product key.

This will activate Windows 10 Pro but it will not be acivated and you won't have access to some of the features. Do this again, but instead of entering in the other key, enter in your Windows 8.1 key, then you will have activated Windows 10 Pro!
