Create a Custom Detection Script for Open-Shell (PowerShell)


Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of Open-Shell using PowerShell.

How to Create a Custom Detection Script for Open-Shell

Open-Shell (File Detection Method)

## Check for Open-Shell (File Detection Method)
$OpenShellExe = (Get-ChildItem -Path "C:\Program Files\Open-Shell\StartMenu.exe","C:\Program Files (x86)\Open-Shell\StartMenu.exe" -ErrorAction SilentlyContinue)
$OpenShellExe.FullName
$OpenShellPath = $($OpenShellExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($OpenShellExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with Open-Shell File Detection Method
$FilePath = "C:\Windows\Temp\Open-Shell_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$OpenShellPath`",`"`${Env:ProgramFiles(x86)}\$OpenShellPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the Open-Shell Detection Method script required to detect the current version of Open-Shell that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Open-Shell\StartMenu.exe","${Env:ProgramFiles(x86)}\Open-Shell\StartMenu.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "4.4.170"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Open-Shell (Registry Detection Method)

## Check for Open-Shell (Registry Detection Method)
$OpenShell = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Open-Shell' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$OpenShell.DisplayVersion
$OpenShell.PSChildName

## Create Text File with Open-Shell Registry Detection Method
$FilePath = "C:\Windows\Temp\Open-Shell_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($OpenShell.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($OpenShell.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($OpenShell.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the Open-Shell Detection Method script required to detect the current version of Open-Shell that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{F07C0CF2-6021-403A-99CA-1164340B09FB}','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{F07C0CF2-6021-403A-99CA-1164340B09FB}' -Name DisplayVersion -ea SilentlyContinue) -ge '4.4.170') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
