finding windows 10 pro product key in registry

I then went to change my product key for windows for the Pro one and after that, the store installation of Win10 Pro upgrade worked and after reboot I was on Win 10 Pro.

As I had not received any product keys to any of the windows versions (even the 10 Pro upgrade just installs, you don't get the actual key in any email, receipt, order confirmation, etc.) I then used ProduKey, as suggested also in this thread, and saw that I was on a different product key and the Pro key was also shown by ProduKey. It seemed to install something, and after reboot, I was still on Win 10 Home. The good thing about this system is there’s no. The store showed the Pro upgrade first as 'buy, costs XXX', but later it changed to 'begin installation', but it did not work. What a digital entitlement means If your PC has a digital entitlement, Microsoft keeps a record of your right to run Windows 10 on its servers. I spent some time in the support chat with MS guys, with no help from them, not even with my order id or invoice number (for the Win10 Pro upgrade). I installed Win7Pro and after that Win10Pro to a separate partition, both as UEFI. I changed my original 256GB SSD out and replaced it with a 512GB SSD (This might be the cause for auto-activation failing, some of the support pages of microsoft said something like 'if you do considerable hardware changes, like motherboard or hdd, you need to activate with Support'). I had some issues with the Win10 (probably because of the 8.1 -> 10 upgrade), and had a need for Win7, so I decided to do a clean install of Win7Pro/Win10Pro dual boot. Upgraded to Win10 soon and later to Win10Pro (through the store). After you register on first start up any reinstalls on the same machine will automatically retrieve the MOBO info.
