Is it possible to uprade Home 7 or 8.1 Core to 10 Pro?

Hello! We all know that any version less than Pro will be upgraded to Windows 10 Home. That is Windows 7 Starter, Windows 7 Home Basic, Windows 7 Home Premium, Windows 8 Core will all be upgraded to Windows 10 Home. If later someone wants Windows 10 Pro he/she can do it from the Windows Store by paying and upgrading Windows 10 Home to 10 Pro. The question is if we can avoid this two-step upgrade and make it an one step upgrade. Is it possible to buy a Pro license and use an ISO or DVD to upgrade to Windows 10 Pro directly? Once I tried to upgrade a Windows 8.1 Core system using a DVD, but I wasn't offered any choice, it was upgraded to Windows 10 Home. Of course we can always upgrade 8.1 Core to 8.1 Pro (and 7 to Professional or Ultimate) and then upgrade to Windows 10 Pro, but this is again a two-step procedure. Any workaround?

Well if you have a Win 10 Pro ISO, it should ask you for a product key to upgrade install pro

Yes, but you missed one little detail. The same DVD-ROM can install both Windows 10 Home and Windows 10 Pro. It depends on the license key (for clean installation) or on the previous Windows version (for upgrade). This is what I thought, since it can also install Pro I will be given the choice, but I wasn't. Since the system was Windows 8.1 Core it upgraded to Windows 10 Home without giving any choice other than a clean install, of course, which I didn't want to do and lose everything else. I didn't tried to boot from the Windows 10 DVD-ROM and start setup from there, but chances are that either it won't allow upgrade (it will suggest starting setup within Windows) or it will again force Home.

I imagine this is one step: or am I missing something?

I suspect you can make a full installation using the included serial, but not an upgrade from Home to Pro... Who knows?

Ok how about you allow the upgrade to 10 core once that is complete you would use (WINKEY + I) Settings/updates and Security/ the dialog will come up to add Pro and you would input your key. The pro features will be available nothing further is required. While still two steps the 2nd step is about 1 minute or less.

So you can upgrade from Home to Pro without any installation being required? That is interesting. I didn't know that!

Yes that is correct, Binks Tutorial is very detailed if you need that its pretty simple actually.

If you suggest to simply click on "Change Product Key" and set a Pro key, it won't work! I've already tried that. You must click on "Go to store" and purchase the Pro key. This is to make sure that you have actually paid for the key and it is genuine. The upgrade process could be about 10-20 minutes, at least so it was to upgrade Windows 7 Home Premium to Ultimate.
