Windows 10: hardware change lost upgrade to pro

I sent my laptop in for repair and the motherboard was replaced. They reset windows to Windows 10 Home. I had upgraded to Windows 10 Pro then to 11. Now I can not get it to install without purchasing a new copy. There has to be an easy fix to this. It must happen fairly often.

Activating Windows 10 Pro After a Hardware Upgrade!

I followed all the steps to linking my Windows 10 Pro to my Microsoft account so that I could upgrade my hardware, reinstall Windows 10 Pro, and activate it, but it's not working. I'm signed into my Microsoft account. I tried the activation troubleshooter,
selecing that I recently changed hardware, etc. Nothing is working. I can see my old computer under my Microsoft account, as well as my new one (with better hardware). I changed the motherboard, ram, and CPU. Any suggestions would be wonderful.

 

Windows 8 Pro Retail => Windows 10 Pro (Free upgrade) Fails Activation after hardware change

Hi,

I bought 2 retail licenses (one for my desktop and one for my laptop) for Windows 8 several years ago and upgraded to Windows 10 (via the free upgrade). Recently I had to change some hardware (motherboard) and I get the following error code when trying to
activate Windows: 0xC004C003.

I have tried the following, all of which have failed.

1. Troubeshoot -> I recently changed hardware on this device (I can only see my Laptop License and not my desktop)
2. Provided the Installation ID (via phone helpdesk) on two occasions.

First help desk technician suggested I buy a new Windows License and the second suggested I reinstall and use Windows 8. Both suggestions from help desk are ridiculous.

How do I proceed without having to:

1. Pay for a license I should technically already have
2. Downgrade back to Windows 8 (loose time / data)
