Is there an easier way to get Admin user information from remote desktops?

Hello Experts,

Is there an easier way to express the parameters, variables and cmdlets to retrieve Admin user information from desktop computers?

The script below seems verbose and overly complex. Why is there a  [ADSI]"WinNT:// syntax and "^Winnt\:\/\/(?<domainName>\S+)\/(?<CompName>\S+)\/") string within the try-catch syntax?

If you could please add perspective, I'd surely appreciate your insight. Thank you.
