Retrieve value from computer via powershell ans put it in inventory

Hi,

I wanted to retreive the Windows Defender signature version and the date it was last updated. I can retrieve this via a registry scan. The update date is in binary format so this is pretty useless in this form. Is there a way to return a value via powershell, for instance via this command:

[datetime]::FromFileTime([BitConverter]::ToInt64((Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows Defender\Signature Updates').SignaturesLastUpdated,0))

and put this in a custom field or variable, or some other place so that I can build a collection with it?

regards,

Guy

    We are planning on adding a PowerShell scanner to PDQ Inventory that would allow you to do things like this, but I have no ETA on when it will be ready. In the meantime, one thing you can try is to write a PowerShell script that stores your converted data in WMI, run that script with Deploy, and set the Scan Profile on that package to a WMI scanner.

    Here's a rough proof-of-concept script I found in my notes for storing data in WMI:

    param (
        [string]$ClassName,
        [array]$Properties,
        [string]$Namespace = "root\CIMV2"
    )

    $NewClass = New-Object System.Management.ManagementClass("$Namespace", [String]::Empty, $null)

    $NewClass["__CLASS"] = "$ClassName"
    $NewClass.Qualifiers.Add("Static", $true)

    ForEach ( $Property in $Properties ) {

        $NewClass.Properties.Add("$Property", [System.Management.CimType]::String, $false)
        $NewClass.Properties["$Property"].Qualifiers.Add("Key", $true)

    }

    $NewClass.Put()
