You do know there is more than one way to download Windows 10 to do the upgrade, right? They go to the Windows 10 Media Creation Tool website, they pick the create media for another computer option, they click English, they download the wrong edition - N or Single Language when they needed regular Windows 10 - or regular Windows 10 when they needed N or Single Language. They pop the USB drive they made into the machine and run setup.exe. It asks for a product key. Because they are attempting to upgrade to the wrong version. If they click skip - their Windows 10 will not activate.
If they are upgrading to the correct version, it will not ask for a product key.
But, hey, whatever. I've got 9 computers at my house running everything from 32-bit Windows 10 Home to 64-bit Windows 10 Pro and one I am dual booting between Home and Pro. If the OP upgrades and activates it's all good. If he skips entering a product key during the upgrade and ends up with a non-activated Windows 10, we'll tell him how to fix it.
