Windows 10: Why my Windows product key changing after I activated Office?

I just get an Office product key using Tisztaszoftver, but it changed my Windows product key and the version from Pro to Enterprise. After I deinstalled Office and changed the product key back, it seemed good, but seconds later, product key changed to the Enterprise version.How can I change the my product key back to Pro version without automatic change?

Product key

Hi Megan,

A product key is used when activating a software.
To help us determine the appropriate troubleshooting steps that can resolve your concern, we'd like to ask the following questions:

• What product are you trying to activate?

• Are you looking for the product key to activate your Windows?

We look forward to your response.

 

What is an "ACTIVATION KEY CARD" for Office 2013 ?

ok MisterEd, My screenshot below shows what you directed me to.

I then entered the Product key and it took me to the next screen.



Am I going to have to do this each time I use new app in Office 2013 ? Such as Excel, PowerPoint, Publisher etc ?

 

Windows 10 product keys and activation - and the KMS angle

Changing the product key to the generic Windows 10 product key will reset activation to the standard retail channel for activation. It might just activate (if there was a previous digital license for Windows 10 for that computer established with Microsoft). Once Windows 10 is back on the retail activation channel, then more than likely changing the product key to the Windows 8 product key using the same method may work.
