How It Works:
- Get-CimInstance -ClassName Win32_ComputerSystem queries the same class used earlier for hostname lookups - it also holds domain/workgroup membership info.
- Domain shows the domain name if the machine is domain-joined, or the workgroup name if it isn't.
- PartOfDomain gives a direct True/False answer to whether the machine is actually joined to a domain (as opposed to just being in a workgroup with the same displayed name).
- Workgroup is populated only when the machine is not domain-joined - on a domain-joined machine, this typically shows blank, since Domain already covers that case.
