Windows 10: Product key for win10 Pro

How can I get a product key for Win 10 Pro? I upgraded from Home edition online at Start menu and paid the $99 fee.At first I got an error code 0x80070005. I rebooted and according to "System/About" I have Win 10 Enterprise but I can't activate without either a product key or a Digital license.Thanks,Chuck

Win10 Pro Product Key

I upgraded from Win7 Pro to Win10 Pro a few years ago. I am now receiving a message in Settings saying that my product key is for Win 10 Home. This is not correct. It is, and always had been, a valid and activated installation of Win10 Pro.

Why is this happening?

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.

 

Actvating Win10 PRO with a Win8 PRO product key

As it says on the tin...I'm struggling to activate Win10 PRO with a Win8 PRO product key....

This is my 3rd....and hopefully last significant hardware (mobo) change to my system for a while.

Activation was via a digital licence, and I was able to use the Win8 Pro key for the birth of the last 'creation.'

Currently....I'm given to understand that only a Win10 key can be used....and I don't have that!

Tried troubleshooting...and online Help (Ha ha)....but no good so far.

Please Help!!!
