Powershell script to retrieve all detection method scripts and output them

Last year i wrote a blogpost about how to get all the powershell scripts used as detection methods and since then i have refined that script a bit and also added logic for it to now output any detection method using scripts regardless if its Powershell, VBScript or Javascript.

I hope this can be useful to someone out there in cyberspace.

		Retreives and outputs scripts used by detection methods. 
[CmdletBinding(DefaultParameterSetName = 'DestinationPath')]
[Parameter(Mandatory = $true,
Position = 1)]

[String]$Filepath = $DestinationPath

$SiteCodeObjs = Get-WmiObject -Namespace "root\SMS" -Class SMS_ProviderLocation -ComputerName $env:COMPUTERNAME -ErrorAction Stop
foreach ($SiteCodeObj in $SiteCodeObjs)
if ($SiteCodeObj.ProviderForLocalSite -eq $true)
$SiteCode = $SiteCodeObj.SiteCode
$SitePath = $SiteCode + ":"

Import-module ($Env:SMS_ADMIN_UI_PATH.Substring(0, $Env:SMS_ADMIN_UI_PATH.Length - 5) + '\ConfigurationManager.psd1')

if (-not (Test-Path $DestinationPath))
new-item -Path $DestinationPath -ItemType Directory -Force

Set-location $SitePath

$Apps = (Get-CMApplication)
foreach ($App in $Apps)

$Script = ([Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($App.SDMPackageXML)).DeploymentTypes[0].Installer
if ($Script.DetectionScript -ne $Null)
$PSscript = ([Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($App.SDMPackageXML)).DeploymentTypes[0].Installer.DetectionScript

Switch ($PSscript.Language)
"PowerShell" { Out-File -FilePath "$Filepath$($App.LocalizedDisplayName).ps1" -InputObject $PSscript.Text }
"VBScript" { Out-File -FilePath "$Filepath$($App.LocalizedDisplayName).vbs" -InputObject $PSscript.Text }
"JavaScript" { Out-File -FilePath "$Filepath$($App.LocalizedDisplayName).JS" -InputObject $PSscript.Text }






You need to run script locally from your siteserver.

get-DetectionMethodScripts.ps1 -DestinationPath "C:\temp\scripts\"


and it will output all the detection methods that uses scripts to that folder. One for each application and names the file after the application.


Until next time, cheers !

  1. Hi , I Am looking for a very script to list the machines which are having the C$(Admin Share Access) on client machine.

  2. I think there is an error somewhere in your script.
    I get this output when I run it on windows 10

    Get-WmiObject : Invalid namespace "root\SMS"
    At C:\Users\administrator.ICTWEBMAIL\Desktop\test.ps1:24 char:17
    + ... eCodeObjs = Get-WmiObject -Namespace "root\SMS" -Class SMS_ProviderLo ...
    +                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : InvalidArgument: (:) [Get-WmiObject], ManagementException
        + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand
    1. You need to run it on your Siteserver, the error message says it can’t find the namespace “Root\sms” which exist on your site server. I will clarify that in the post. Thanks

      1. Maybe you should ask it when executed like the dir to store the data in ๐Ÿ˜‰

  3. Script will fail if an application has a slash in its name:

    Out-File : Could not find a part of the path 'C:tempreportDisplayLinkUSB Dock drivers and software.ps1'.
    At C:tempGet-DetectionMethods.ps1:57 char:16
    + ... werShell" { Out-File -FilePath "$Filepath$($App.LocalizedDisplayName) ...
