Windows 10: Windows pro product key re-usability

This is an informative question regarding the policies of windows. I have an existing Microsoft Windows Pro software installed on one of my devices, I wanted to know if there is a way using which I can use that product key on my another device which has Windows home installed in it, to upgrade it to Pro. If the policy requires the earlier existing systemwith windows pro to be abandoned or removed in order to allow the product key of pro to be used in a new system, that too works for me.

Please help me by suggesting me steps to take.


Thank you

:)

 

Usable Product Keys for Enterprise downgrade to Pro


Hello wetenhr, and welcome to Ten Forums.

You could downgrade to Windows 10 Pro using the generic key under step 1. You'll still be using the same version that you currently have installed, but you will be able to update to the latest version and build via Windows Update.

When it's finished downgrading, you could try to activate Windows 10 Pro with your Windows 7 Pro or Ultimate key. If unsuccessful, you may need to purchase a Windows 10 Pro key from the Store to use to activate with.

 

Why was I not asked for a product key when upgrading to Win 10?

According to your spec you have Win 10 Pro, but perhaps that doesn't reflect your PC.

You haven't stated which edition of Win 10 you have on this machine, nor what your Win 10 key is for.

For example, if you already have Win 10 Pro and your key is Win 10 Home, that would be a retrograde step.

Can't upgrade from Windows 10 Home to Pro

Hi Bill,

Thank you for posting your query in Microsoft Community. We apologize for the inconvenience caused and will assist you in the best possible ways.

I suggest you to download and create an installation media for Windows 10 Pro form the link provided below:

Download Windows 10

After the installation media is created, suggest you to upgrade to Windows 10 Pro from the installation media. When the upgrade asks for product key, enter the product key purchased for Windows 10 Pro. If it does not accept, suggest you to skip the activation

• Press “Windows key + R” and type “slui 4” and press Enter.
• Select the Region from the list and click Next.
