Medion Desktop - 8VNSLQR running W10 Pro, needs to be W10 home, reset advice?

[SuttonWillow]

My father bought a Medion Desktop with W7 operating system, 64bit. He then had an upgrade to W8 and soon after to W10. He found it too difficult to manage so he hived the PC off to me. 

I plugged it in but am plagued by "Activate Windows"messages. Windows was always activated previously.

I have retrieved the key and tried to activate but it appears that the W10 operating system installed is W10 Pro and should be W10 Home. 

I imagine I'm going to have to atempt a complete re-install but am unsure about how to do this and whether it will install with W10 pro or home. 

I'm not very PC techie savvy so would appreciate any advice you could offer.

I have no recovery disc but there is a partitioned hard drive. 

Thank you.

Hi @SuttonWillow , welcome to the FORUM!

Indeed, you will need to reinstall Windows.

Please find instructions on how to do so on this link here

You will be able to select which version to install, so please make sure you choose W10 Home.

Your activation key should be enough to activate W10 later.

Don't forget that you can always contact Microsoft support if you need it.
