Windows 10: Windows 10 Home to Pro with Windows 7 key lost

Hello, well... I'll start thanking whoever can help me with this.

A couple of months ago I bought a computer that came with Windows 10 Home preinstalled. I wanted to upgrade to the pro version so I used a product key of Windows 7 Professional to do so, everything worked fine, the Activation Wizard accepted the activation key and updated adding the new features.


The thing is that I recently bought an SSD for my computer so tried to migrate my Windows installation to it and it did not go well. At the end I could not boot the software anymore so I was forced to do a clean installation process and it activated the Home version instead of the Pro directly. The issue is that when I try to follow the same process of activating the Pro version again how I did it before it gives me an error 0xc004f050 stating that my key just didn't work.

Is there a way to activate my Windows Pro again?

:)

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

I just did a deployment last night with a fresh 10 install using the newest ISO and a 7 Pro key, worked like a charm. Glad yours worked for you as well. *Toast :toast:

 

Installing Windows 10 using Windows 7 key

Two quick ways to use your Windows 7 key during the install:

1. When asked for the serial #, put in that Windows 7 serial # and continue on. It should activate as soon as it hits an internet connection.

2. When asked for the serial #, at bottom of window click on the I don't have a serial # text (or whatever it says). It will then ask what version you want to install, ie. Home or Pro. Be sure to install the right version that matches your Windows 7 key. Then once you get into windows you can activate by putting in the key. Some people prefer this method, not sure why honestly. Easier to do #1, since the installer will see your key and know which flavor of Windows 10 you are trying to install.
