Active Directory Group Cleanup - Help Needed

Question

Hi All,
I need to clean up our Active Directory and the first stage of this is to remove any unused groups. I have been trying to work out what these are using powershell. Can anyone please provide me with a simple powershell script that will identify any AD groups
that have no members in them? 
Many thanks
James

Greetings!
Try this:
import-module activedirectory
Get-ADGroup –Filter * -Properties Members | where { $_.Members.Count –eq 0 }
Regards.

How to query members of 'Local Administrators' group in all computers?
Adding in: Watch out for users having customized groups (e.g groups other than Domain Users and Domain Admins) as their primary group, they will not be reflected in the member attribute and hence not be reflected in the above count, I know it's a rare case,
but could be good to know.
