Installation and Activation of Windows 10 Pro

So did I, and on the desktop too.

What's worse, is that even those knowledgeable enough to know how to upgrade and clean install still won't have a clue that Windows 10 Home installed and he no longer has the Pro that he paid for!

It was brought up on the Microsoft MVP Yammer group, and the replay from a Microsoft representative was, "this is by design". That's the way its supposed to work.
In most cases (but not all) the correct version is installed. If the key in the BIOS was for the OS you did the free upgrade from, its all good. You get the correct version.
In you upgraded your OS with a Retail key though, its not going to give you the version you got via the free upgrade.
Worst case scenario, somebody buys 10 Home to save a few bucks. Even though their PC came with 8.1 Pro. They will get Pro, which won't activate, and can't upgrade from Pro to Home with a key change.
Granted, that won't happen very often. Still, I wouldn't want to be that person trying to sort that out.

Forgot to add, right now, if that happens. That PC gets a digital license for 10 Home. At some point I expect that to stop. It shouldn't happen now. The free upgrade is officially over. So some time down the road they will get an unactivated 10 Home instead of an activated 10 Pro.

Since I received Win10 as the free upgrade from Win 7 Pro, I qualified for the Pro upgrade as well. Turns out, I can use my old Windows 7 key to install the Win10 Pro upgrade.

Until MS actually stop it doing this.

I was really hoping the 1607 AU wouldn't use 7 and 8 keys, especially the Windows 8 OEM embedded keys.

Yeah, I do believe if Home is already installed, change product code will reject Windows 7 and 8 keys. You get an incorrect version (something like that) message. Only Windows 10 Pro keys are accepted at that point.
On a clean install, if you actually get the prompt to enter a key, they will be accepted. It's a mess, IMHO.

Yes, Guy, using the Product Key guarantees you will get the proper build; however, the ISO doesn't ask for a key, so if the computer came with Windows 8.1 Home (embedded in BIOS).

Have you installed the ISO on the former Windows 7 machine? We'd like your experience.

They really shouldn't, because right now, that's the only way to get Windows 10 Pro installed! Unless Installation stops reading my BIOS and starts to read my "digital license"!

If they stop letting you enter those Windows 7 and 8 keys, logic would dictate that the install media would also stop reading Windows 7 and 8 keys from the BIOS. In that situation you would get the enter a key prompt. Then when you click I don't have one, you would get the selection menu with the options to install Home or Pro. That's the way I would like to see it work. Only look for Windows 10 OEM Embedded keys.
