Windows 10 Instalation

[MrThunder331]

So I recently built my wife's new computer. The basic issue im having is that i bought a Windows 10 Home Product Key from Newegg, but the OS that is on her PC is a Windows 10 Pro apparently. According to the error code that comes up when I insert the Product Key in to the Activation Key for Windows, it doesn't detect the Product Key as being legitimate because its not a Pro version of Windows 10. 

 

I've been searching for resolutions, and I've tried a few out. I've tried several fresh installs of windows 10. I tried a Registry Edit were I changed 4 of the Registries to Windows 10 Home and then did another fresh restart. I also tried downloading a fresh restart program from the windows 10 help page, as well as the complete wipe windows install program from the same page, one of them didn't even get past the start the installation because it detected that Windows 10 Pro was installed and not Home.

 

The start of it all was that I reused her old HDD with the OS still installed in the new computer, and I migrated the OS to one of the new SSD's that I put in the PC. The hardware is a ASUS 470X, a Ryzen 2700x, a 1500w PS, a Noctua CPU cooler, a nvidia 960 video card (yes its going to get an upgrade when we can afford it), a 500GB Evo 970 M.2, a 1TB 960 Evo, and the old drive is a Blue HDD.

You can try the below to move the version, though it's typically used to upgrade, I don't know if it works to downgrade.

 

From a Elevated Command Prompt:

 

dism /online /Set-Edition:Core /AcceptEula /ProductKey:12345-67890-12345-67890-12345

 

Replace the product key with yours.

@MrThunder331 I made a typo in my first post. I've edited it, so make sure you refresh the page before using the code. (Put /Accept-Eula but it should be /AcceptEula)

unfortunately, this didn't work. so im trying to get in contact with Microsoft's abysmal customer support.

Why didn't you just install Home then??

I did...I've tried to do just that several times. The computer OS on the SSD recognizes that it already has Windows 10 Pro, and then says that the Windows 10 Home key is not legitimate.

Huh? If you're not erasing it in the process it's not a "fresh install".

well the offered fresh install in the menu still retains the pro version some how. I did find a plug in to download on the Microsoft website that was for fresh installs, however it sees that i don't have windows 10 Home installed and just closes itself without doing anything.

In the installer you choose the bottom option, then at the drive selection you don't just click next, you actually format the partition manually, THEN install on that. 

Obviously supposing you have no data you want to keep on the drive.
