Create a Custom Detection Script for Microsoft Edge WebView2 Runtime (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 Microsoft Edge WebView2 Runtime using PowerShell.

How to Create a Custom Detection Script for the Microsoft Edge WebView2 Runtime

Microsoft Edge WebView2 Runtime (Registry Detection Method)

## Check for Microsoft Edge WebView2 Runtime (Registry Detection Method)
$WebView2 = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Microsoft Edge WebView2 Runtime' } | Select-Object -Property DisplayName, DisplayVersion
$WebView2.DisplayVersion

## Create Text File with Microsoft Edge WebView2 Runtime Registry Detection Method
$FilePath = "C:\Windows\Temp\Microsoft_Edge_WebView2_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft EdgeWebView','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft EdgeWebView' -Name DisplayVersion -ea SilentlyContinue) -ge '$($WebView2.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the Microsoft Edge WebView2 Runtime Detection Method script required to detect the current version of Microsoft Edge WebView2 Runtime that is installed on the device you are running the script from.
