Who is the issuer of this Personal certificate

In the certificate store of my Windows 10 PC (not joined to a domain) there is a certificate under Personal as follows:

subject=/CN=0c4e397b-ea9d-48a5-9cfc-0366effbd081
issuer=/DC=net/DC=windows/CN=MS-Organization-Access/OU=82dbaca4-3e81-46ca-9c73-0950c1eaca97

This certificate is used when a web site I visit requests for client certificates.

Who is the issuer? Is it a global CA or is it something local to my machine? I can't seem to find it in the certificate store on my PC. Where can I find more information about this issuer?

Solution 1:

The certificate is used for associating the unique Windows device against a device object record stored within the Azure Active Directory.

The certificate has been generated by the Azure Device Registration Service based on a certificate signing request generated on the device during the Azure AD Join process.

The Azure Active Directory documentation contains general overview about the topic and this TechNet article describes the Azure AD Join process in detail.
