Upgrade Home to Pro

I understand that my Microsoft Account allows me to install Windows 10 on multiple computers. I currently have one desktop and two laptops running Windows 10 Pro v. 1909. One of those laptops is dying and I have replaced it with a new laptop with Windows 10 Home v.1909 installed. I would like to take advantage of my ownership of Windows 10 Pro in the laptop to be discarded to upgrade the new laptop from Home to Pro. Will my MS account cover me in doing so and if so, how to proceed.

Note: I have tried to install Windows 10 1909 ISO from a thumb drive, keeping no files or programs to get a clean install, and the program would only install Window 10 Home.

Thank you for your help

I downloaded the 2004 ISO file for both PC`s the other day, and already I`ve forgotten if it gave me a choice.

No, there's just one ISO offered by the MCT, it contains all editions, Home, Pro, Education, etc.

First of all, any ISO of Windows 10 obtained through any legitimate means will be the multi-edition ISO file. It's not an option. It's the standard. If you get an ISO file that contains only Windows 10 Home, or only Windows 10 Pro then it is an ISO file that has been modified by a third party.
@seattlerust,

If you want to upgrade your Windows 10 Home to Pro and attempt to activate it via your Microsoft Account, this is how you do it. Be aware, once you upgrade from Home to Pro, the only real way to go back to Home is to restore a backup image you make before the upgrade, or do a clean install of Windows 10 Home. There is no guarantee whatsoever that activating your Windows 10 Pro via your Microsoft Account will work.

1. Disconnect the computer from all sources of internet connection.
2. On the Activation Screen under Update and Security in Settings, click the link to change your product key.
3. Enter the generic Windows 10 Pro product key: VK7JG-NPHTM-C97JM-9MPGT-3V66T. NOTE: if you are connected to the internet, this will fail.
4. After the upgrade to Pro completes, reconnect to the internet. Then attempt to activate it via your Microsoft Account:

Good Luck!

Thank you all who replied to my question.
I am now convinced that my new laptop has an OEM operating system which indicates that the license key is embedded in the UEFI chip. So most attempts to push a Pro OS onto the computer will fail, even formatting the HD as part of the process. I seriously considered the method suggested by NavyLCDR but decided against it. Basically, I don't really "need" Pro. I m just used to it as I have had Pro on my computers for many years. The only "need" would be its capability for better controlling the timing of Miscrosft upgrades, and I guess I will just have to work around that in other ways. One interesting thing I found in this exploration was on the old laptop that I am replacing; when I checked to determine the license key on that laptop, I found the MS default key. That machine began life with Windows 7, and was upgraded from 7 to 8.0, then 8.1 then finally through all of the subsequent iterations of Windows 10 up to vers. 1909. Always activated. Default Key? Go figure.

So thanks again. Always good to learn things.

No, that is normal. Any machine upgraded from 7/8/8.1 to 10 gets the appropriate default key for its edition, Home or Pro. The activation is not from the default key (that can't activate anything) it's from the digital license given to the PC on successful upgrade. This digital license is stored on the MS activation servers and linked to the hardware ID of the PC.

With a digital license you can clean install the same edition without providing a key, it will activate automatically from the digital license.

Good to know, Bree. Thanks again.
