Salvage Win10 Home, upgrade to Pro

Hello Great Group,

I am interested in steps I might take to salvage my Windows 10 Home license from a dead computer's drive, then upgrade to Pro on a new computer. Is this possible? If so, how?

Details: 'Puter hanging issue became fatal, then died, I borked the BIOS, made a mess, building a new machine and plan to harvest as much as possible from the old drives. I have a backup of C: where Win10 lived as well as two identical SSDs (both with Win10 on them), yet do not want to boot from one of the old disks fearing that 1) Windows may be corrupted, or 2) The drive might have some nasties on it.

Upgrading from Home to Pro is about $100? cheaper than just buying Pro. So, I'd like to upgrade from the old license if possible, but I'm not sure what steps to take and in what order in order to accomplish this mission.

Are these the correct steps? (I'm guessing)

Build the new computer
Update BIOS if necessary
Install Win10 Pro without key
Attach old drive
Scan old drive with Malwarebytes
Run Belkin Advisor on that drive to reveal key?
Enter key into Pro?

I've no clue what might happen at this point. Key invalid? Upgrade to Pro somehow?

Thanks in advance for your insight.

 

Win10 Pro

Hi, I bought a Win10 upgrade license on my old laptop. At the time I had a lot of issues upgrading the OEM Win10 Home as the upgrade purchase didn;t come with a product key. After lots of phone calls with MS they eventually provided me with a product key
and the laptop was upgraded to Win10 Pro.

I now have a new laptop and still require the Pro functionality. Following the steps here (which also tells me my Win10 Pro upgrade license is transferrable):

How to Transfer your Windows 10 License to a New Computer

the OEMM Win10 Home didn't upgrade using the MediaCreationTool (it just offers to install Win10 Home), and the System > Upgrade and Settings > Activation upgrade function doesn't accept the product key I've purchased.

Any help would be appreciated - although useful Win10 is awful to upgrade and MS seem to have deprecatated a lot of their contact options.

 

win10 pro upgrade from win10 home

I'm upgrading my home edition to pro which I have done before with other win10 home pc's, don't need or want the hassle of a new install.
I got a win10 pro, its the full pkg, with an install cd.
first I did the change key with the generic win 10 pro key, reboot, and then change key again to the new win10 pro, got the success message. however after checking system status with showkeyplus, it reports I have win10 pro but with a completely different key from the win10 pro I bought and installed. and has the message:
"* Default key - requires a Digital License for activation"

not sure where this has gone askew or if there is some other step in this simple process I'm missing
