Create a Custom Detection Script for CPU-Z (PowerShell)

by

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 CPU-Z using PowerShell.

How to Create a Custom Detection Script for CPU-Z

CPU-Z (File Detection Method)

## Check for CPU-Z (File Detection Method)
$CPUZExe = (Get-ChildItem -Path "C:\Program Files\CPUID\CPU-Z\cpuz.exe","C:\Program Files (x86)\CPUID\CPU-Z\cpuz.exe" -ErrorAction SilentlyContinue)
$CPUZExe.FullName
$CPUZPath = $($CPUZExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($CPUZExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw

## Create Text File with CPU-Z File Detection Method
$FilePath = "C:\Windows\Temp\CPU-Z_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$CPUZPath`",`"`${Env:ProgramFiles(x86)}\$CPUZPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge `"$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 CPU-Z Detection Method script required to detect the current version of CPU-Z that is installed on the device you are running the script from.

Example: 

If([String](Get-Item -Path "$Env:ProgramFiles\CPUID\CPU-Z\cpuz.exe","${Env:ProgramFiles(x86)}\CPUID\CPU-Z\cpuz.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge "2.0.2.0"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

CPU-Z (Registry Detection Method)

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

## Create Text File with CPU-Z Registry Detection Method
$FilePath = "C:\Windows\Temp\CPU-Z_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($CPUZ.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($CPUZ.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($CPUZ.DisplayVersion)') {"
Add-Content -Path "$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 CPU-Z Detection Method script required to detect the current version of CPU-Z that is installed on the device you are running the script from.

Example: 

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\CPUID CPU-Z_is1','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\CPUID CPU-Z_is1' -Name DisplayVersion -ea SilentlyContinue) -ge '2.02') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
