Windows 10: Windows 10 Home upgrade to W10 Pro with a product key fails

Hello Community.

I have a new Dell XPS15 64bit with W10 Home.

My old laptop has a goosed display and I have located from its hard drive the Key from my W10 Pro.


But when I try to upgrade my Dell XPS15 using the Product key from my old laptop W10 Pro the process fails to recognize the key and posts the following:"Unable to Upgrade your Edition. We cant Activate Windows on this device because you don't have a digital license or a product key. If you do think you have a valid license or key, select Troubleshoot below (0x803fa067).


My Dell W10 Home is fully activated.


Any help would really be appreciated.


Thanks

:)

 

Win10 Home to W10 Pro Upgrade Error using Product Key

The keys are there because 1. It is the product key you end up with when you gain a digital license for Windows 10 Pro through legitimate means and 2. When you do a clean install of Windows 10 (without adding an ei.cfg file), on a computer with a product key for Windows 10 Home stored in UEFI, you can use the generic product key to upgrade the Windows 10 Home that installs by default to Windows 10 Pro - but only if you have an existing digital license for that computer for Windows 10 Pro previously stored on Microsoft Activation Servers.

The reason the generic Windows10 Pro product key will not upgrade your Windows 10 Home to Pro is because you do not have a preexisting digital license for Pro for that computer stored on Microsoft activation servers.

 

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).

 

Reusing W10 Home product key after upgrading to W10 Pro


A long time ago I upgraded a computer from W10 Home to W10 Pro. This was a custom build and both the original W10 Home activation and the new W10 Pro activation were done via product keys ordered from Amazon.

No Microsoft account has ever been involved with either key. Back in May of this year I completely reinstalled Windows but I don't really recall if I had to reactivate the license or not.

And now I'm wondering if I could reuse the original W10 Home product key on another computer, and if it would affect the current W10 Pro activation in any way. Would the original Home product key still be tied to my main computer's motherboard or did that history get wiped when I upgraded to Pro?
