It wasn't connected to the internet. That was the point. In 2012, a paranoid IT director had built a fortress: an air-gapped network of four servers that held every digital court record, every e-filing, every probate document from the last fifteen years. To access it, you had to physically walk into the basement, log into a terminal, and request a signed token. That token’s chain of trust? It ended with the 2011 certificate.
A root certificate is a self-signed digital certificate that represents the highest level of authority in a security domain. The specifically:

It was, after all, a root of trust. And some roots run deep.
Websites like login.live.com , github.com (owned by Microsoft), and visualstudio.com often present certificates that chain up to Microsoft roots.
Easier said than done. You can't just push an update to an air-gapped network that was built on Windows Server 2012 R2 with a bespoke, undocumented authentication system. The original vendor had gone bankrupt in 2018.
or newer, specifically require this certificate to be present in the Trusted Root Certification Authorities store. Security Foundation : It is part of the Microsoft Trusted Root Certificate Program
