Windows 10: Win7 Pro Retail upgraded free to Win10 Pro need my product key.......

Hi, i built my pc years ago. Win7 Pro Retail upgraded free to Win10 Pro need my product key....... so i can reinstall fresh and start over. I cant find my retail box but the OS is registered and activated to me.


How can i find this within my pc?

upgrade from win10 home to pro using a win8 product key

Is this possible ?

Win7 home on an OEM pc.

I have a win 8 pro ( not 8.1 upgrade retail product key.

If I upgrade win7 hp to win10 home,

can I use the win8 pro retail key to upgrade win10 to pro

edition ?

 

upgrade from win10 home to pro using a win8 product key

I understand the upgrade path from retail or OEM .

What I want to do is use the free upgrade from win7 home

OEM licenses to windows 10 home licenses first.

Then upgrade the windows 10 home OEM version to windows 10

pro version; with the last step to win8.0 pro retail key

On the last step above, will the licenses stay on a OEM licenses or change to retail key ????

or is this not even achievable unless I do the install buy media, usb or dvd.

If that is the case than doing the same method from win7 to win8.0 pro would be a more direct route; but the issue is still if I can upgrade win 7 home OEM to win 8.0 pro with a retail

key??????

If that is the case neither route will get the end results win7 home to win 10 pro; unless at one time I do the upgrade with media, usb or dvd, wiping what ever previous operating system was installed before that one.

Win7 home to win10 home or win8.0 pro; then upgrade to win10 pro with a mix of OEM and retail keys.

Thanks

 

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.
