Windows 10 is Activated Using Organization's Activation Service Instead of Digital License
Solution 1:
I recently had an SSD installed at a computer shop, had them make it my primary drive, and had them install Windows 10 on it.
Contact the shop, and have them change the Windows Key to your original license.
Your own key should have been used and will work. You can always change a disk on a Windows 10 computer. I have done this myself.
The shop is responsible for this and should do it for you.
