Extending Hardware Inventory for System Center Configuration Manager

I would like to contribute by adding the certificate model output to the script.

## Delete any existing instances
$CurrentEA = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
(Get-WmiObject -Namespace root\cimv2 -class cm_CertInfo).Delete()
$ErrorActionPreference = $CurrentEA

## Create Class if it doesn't exist in root\cimv2
$newClass = New-Object System.Management.ManagementClass ("root\cimv2", [String]::Empty, $null);
$newClass["__CLASS"] = "cm_CertInfo";
$newClass.Qualifiers.Add("Static", $true)
$newClass.Properties.Add("Location", [System.Management.CimType]::String, $false)
$newClass.Properties["Location"].Qualifiers.Add("Key", $true)
$newClass.Properties.Add("Handle", [System.Management.CimType]::String, $false)
$newClass.Properties["Handle"].Qualifiers.Add("Key", $true)
$newClass.Properties.Add("Thumbprint", [System.Management.CimType]::String, $false)
$newClass.Properties.Add("Subject", [System.Management.CimType]::String, $false)
$newClass.Properties.Add("Issuer", [System.Management.CimType]::String, $false)
$newClass.Properties.Add("NotBefore", [System.Management.CimType]::String, $false)

$newClass.Properties.Add("FriendlyName", [System.Management.CimType]::String, $false)
$newClass.Properties.Add("ExpiresinDays", [System.Management.CimType]::uint32, $false)
$newClass.Properties.Add("Template", [System.Management.CimType]::String, $false)
$newClass.Properties.Add("ScriptLastRan", [System.Management.CimType]::String, $false)
$newClass.Put()|Out-Null
