And suddenly, the lid fell off...

 The waiting is over and the end result is, of course, uninspiring.

The new motherboard has been accepted into the microsoft family, the digital license that was on the previous, so called obsolete, motherboard has been transferred on my account and after setting up TPM and secure boot in the BIOS, and a few days wait, the system cache on their end updated and they allowed me to download the new version.

There will be more waiting however, I had to order an i/o shield and I won't be able to install this motherboard into my old backup case until it arrives, but it will arrive and I will update the blog with the installation and completion of this particular project.
