PowerShell - Uninstall SCOM Agent Using WMI

Author: Brody Kilpatrick | Created: July 12, 2019

Sometimes you need to uninstall one or more SCOM agents using PowerShell. This script does NOT require SCOM cmdlets or anything special and it can easily be incorporated into a larger script. It uses WMI to perform a clean uninstall.

$computers = 'computer1','computer2'
foreach($server in $computers)
{
     $server
     $app = Get-WmiObject -Class Win32_Product -computername $server | ? {$_.Name -eq 'Microsoft Monitoring Agent'}
     $var = ($app.Uninstall() ).returnvalue
if($var -eq 0)
    {
   write-host "Successfully Uninstalled or was not found."
    }
    else
    {
     Write-host "Uninstallation Failed"
    
    }
  
}

I received the original idea from Ramkumar Natarajan who posted a script on the Microsoft Code gallery. However, this script is simpler and more malleable.
