Create a PS script that detects the presence of an app for Windows

SSlater.T1 5

I want to create a script that I can push through Intune to tell me exactly how many PCs have this software installed.

I have already looked at the software inventory report but it does not seem like a trust worthy source.

Is there a clever way to leverage Intune to provide me with that information in a easy to read and digestible manner.

Please do let me know otherwise I will have to go back and say that this is not something Intune can support me with.

Regards,

Shaun

@SSlater.T1, Thanks for posting in Q&A. For your request, I think you can try to use custom compliance policy to detect if the application is installed.

https://learn.microsoft.com/en-us/mem/intune/protect/compliance-custom-script

Here is an example I found for your reference:

Thanks

I tried your example and replaced the name of the app with name of the app we want to detect and mark as unapproved.

However, in testing all devices whether they had the software installed or not came back as non-compliant.

Have you been able to get this working at all and did you need to change anything in the script?

As far as I understand it, when you import the json it creates the compliance rules so for us it was something along the lines of 'Installation Status is equal to no unapproved apps installed' mark as compliant else mark the device as non-compliant?

Is this correct thinking let me know?

Shaun

@SSlater.T1, Thanks for the reply. For the detection script, this is used to detect if the app is installed on the device. So we need to change the script to refer to your software:

For example, if the registry "HKLM:\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall" existing, I consider the steam soft is installed.

Detection script:

#Look for Steam $InstalledSoftware = Get-ChildItem "HKLM:\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall" if ($InstalledSoftware -like "*Steam*") { $steam = "Detected" } else { $steam = "Not Detected" } return $steam | ConvertTo-Json -Compress

After the detection script is created, then we will create the custom compliance policy, as we want to make the device without the app as non-compliant, so we need to change the JSON to make the setting "Steam" isEquals "Detected"

{ "Rules":[ { "SettingName":"Steam", "Operator":"IsEquals", "DataType":"String", "Operand":"Detected", "MoreInfoUrl":"https://andrewstaylor.com", "RemediationStrings":[ { "Language": "en_US", "Title": "Application Detected", "Description": "Steam has been detected on your device, please uninstall and try again." } ] } ] }

Hope the above information can help.
