Windows 10: How to go back to old windows license?

Hi,

I bought a windows 10 pro license key and I was on Windows 10 home, when I put in the code it asked me to restart my pc. When I logged back in all my apps were disabled and I as stuck in S mode. I troubleshooted and it told me to buy windows when I had Windows home before. I'm stuck on S mode and cant do anything.

Is there anyway of getting my old Windows 10 Home back without installing any 3rd party programs because S mode wont let me?


Please help urgently...

:)

Upgrade Windows 10 Family to Pro with license from old computer

My Windows is in French and "Famille" is the "Home" Version I assume, sorry for the confusion.

By "not activated", I mean I bought the PC with Windows Home preinstalled and it asks for an activation code. I didn't buy a new Windows license along with the PC, since I had in mind to recover the one from the older PC, so this doesn't seem abnormal to me.

NavyLCDR, thanks for the suggestion. I was able to upgrade to Windows Pro. Unfortunately, I confirm that step 4 didn't work. I can select my other PC in the Troubleshooter, but now the reactivation on the new PC fails with the message (translated from French): "Impossible to activate Windows - We can't reactivate Windows on this computer. Try again later." I have no idea why it would work better at a later time.

I completely removed the license from the older PC by the way before running the troubleshooter (i.e. it also asks for a Windows activation code on the old PC now). I made sure that the old PC had an internet connection while doing that so that Microsoft could register the license removal (I assume it does?).

That being said, at some point both PC's were running and were connected to the internet at the same time. Could that be the issue? The troubleshooter implies that it is meant to be used when you replace some hardware in your PC. Maybe it doesn't like that the old hardware is a completely standalone PC that can still run on its own?
