I have array that contains many objects, and I would like to see if they match another array with objects.

$SpecialUsers = Get-ADUser -Filter 'Name -like "Smith"'
$NotSpecialUsers = Get-ADUser -Filter 'Name -like "Joe"'

$ThemUsers = $SpecialUsers | Where-Object {$_ -like $NotSpecialUsers}

Not sure how to write this. Trying to skip Foreach and Compare-Object.

Particularly when you have complex objects (objects with multiple properties) like what is returned by Get-ADUser, the only efficient way you have of comparing is with Compare-Object, and you have to specify which properties of those objects you want to compare in order.  You can't just compare one object to another unless it is a simple object like a string.

Can I ask why the "B" grade? I think I gave you a complete answer.  If you need something more you should ask before awarding anything less than an "A", particularly in such a short time period.
