How to downgrade the Windows 10 Pro to Windows 10 Home (upgraded from Windows 7 Home)

It means there is no way for Win 10 Pro downgrade to Win 10 home (upgrade from Win 7 Home) unless I reinstall the win 7 home then upgrade to win 10 home?

If I do the clean install of that PC installed Win 10 Pro upgrade from Win 10 Home (upgraded from Win 7 Home) and skipped the inserting key steps then connect internet, will my PC activate automatically for Win 10 Home or Win 10 Pro?

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Win 10 Pro upgrade using Win 8 Pro product key

I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

So:

How do I either

• activate the Win Pro upgrade, or
• Get my activated Win 10 home back?
