Windows 10: How do I correctly reuse my license on a new pc I am building?

Hello, I am building myself a new PC. I am changing everything except for the SSD. My Windows 10 OS is installed on the SSD. What is the correct procedure for reusing my license key and OS?Will I have to reinstall the OS even though it's already on a drive connected to the new motherboard?If not, and the OS is already installed, will there be a prompt at some point when I will need to type in the license key?And finally, how do I deactivate the license from the current pc before moving to the new one? I don't really understand what happens if I deactivate, does the OS just stop working instant

Replacing Windows 10 retail license with OEM to reuse the retail license on new build

I built a Windows 10 PC several years ago and purchased a retail license. Now that PC cannot be updated to Windows 11. Can I purchase a Windows 10 OEM license and remove the retail license from this PC and install the OEM license without doing a complete reinstall? I would like to continue using this PC until Windows 10 goes EOL, and an OEM license seems perfect for this use since the PC cannot be updated to Windows 11. I would then like to build a new Windows 11 PC and reuse the Windows 10 retail license I would remove from my Windows 10 PC which can’t be upgraded.

First step
