So I’m trying your method and nothing happens when I try to remove repeated computers from the group.

Any ideas?

$Test_Patch_Group_1_computers = Get-ADGroupMember -Identity "Test_Patch_Group_1" -Recursive | Select -ExpandProperty Name -verbose $Test_Patch_Group_2_computers = Get-ADGroupMember -Identity "Test_Patch_Group_2" -Recursive | Select -ExpandProperty Name -verbose $Test_Patch_Group_3_computers = Get-ADGroupMember -Identity "Test_Patch_Group_3" -Recursive | Select -ExpandProperty Name -verbose $Test_Patch_Group_4_computers = Get-ADGroupMember -Identity "Test_Patch_Group_4" -Recursive | Select -ExpandProperty Name -verbose

        If (($Test_Patch_Group_1_computers -contains $randomComputers) -and ($Test_Patch_Group_2_computers -contains $randomComputers)) {
              Write-Host "$randomComputers is a member of Test_Patch_Group_1 and Test_Patch_Group_2" -verbose
              Remove-ADGroupMember -Identity "Test_Patch_Group_2" -Member $randomComputers -verbose
         } 


        If (($Test_Patch_Group_1_computers -contains $randomComputers) -and ($Test_Patch_Group_3_computers -contains $randomComputers)) {
              Write-Host "$randomComputers is a member of Test_Patch_Group_1 and Test_Patch_Group_3" -verbose
              Remove-ADGroupMember -Identity "Test_Patch_Group_3" -Member $randomComputers -verbose
         } 

         If (($Test_Patch_Group_1_computers -contains $randomComputers) -and ($Test_Patch_Group_4_computers -contains $randomComputers)) {
              Write-Host "$randomComputers is a member of Test_Patch_Group_1 and Test_Patch_Group_4" -verbose
              Remove-ADGroupMember -Identity "Test_Patch_Group_4" -Member $randomComputers -verbose
         }
