The tech giant has removed the automatic upgrade option from PCs that they think may struggle, although that hasn’t barred access entirely.
The most important and commonly-used commands will be discussed throughout this document; an exhaustive list also appears near the end of the document. The authenticator validates that you control the domain(s) you are requesting a certificate for, obtains a certificate for the specified domain(s), and places the certificate in the directory on your machine.
