Windows 10: Can I use my Windows 11 Pro Key in my computer where I changed the motherboard?

I was searching the internet but I kept running into a dead end. There is no link to "Add to Microsoft account" on the activation page. Need help.

We appreciate your reply. For us to know more about the issue, kindly answer the following questions:

• Did you manage to deactivate Windows 10 Pro first before replacing your motherboard?
• Do you still have the written copy of your product key?
• Are you using the same hard disk where your Windows 10 Pro product key has been activated? If not, where is this hard disk?
• Did you replace your hard disk along with your motherboard and CPU?
• What is the edition of Windows activated on your computer? To know, press Windows + S. Type About, and click it.

Meanwhile, we recommend that you deactivate and uninstall your Windows 10 Pro license from your old motherboard and reinstall it back on your machine using the steps below:

  Activation ID and note it down.
• On the same command prompt window, type in slmgr /upk <your Activation ID> and press
  Enter. This uninstalls the product key of the current Windows edition. After a restart, the system will be in an Unlicensed state unless a new product key is installed.

Motherboard change unable to reactivate Windows 10 Pro -

I have searched this topic and everything seems to be almost a year old. This is a homebuilt machine circa 2015. It started with an ASUS FM2+ motherboard with an AMD A5600K processor. It was Windows 7 Pro, upgraded to Windows 8.1 Pro then to Windows 10 Pro.
Saturday the motherboard died. An exact replacement could not be located so a Gigabyte card was installed. No changes to the hard drives. Booted the machine and Windows automatically started and then did a "revert" then installed the latest updates. C Drive was in the red so I deleted all of the old install files using Windows Clean-up. Went to reactivate, checked the significant hardware change and entered my MS account information - The computer (none of my computers) were listed and now it is telling me that I have to spend $200 to buy a copy of Windows 10 Pro.
Have not yet called Customer Support as the computer is at home and I work during the day -
I do have a disk image or two that may be a year old -

Suggestions - should I just shell out the $200 and move on

TIA
