Get Driver Install Dates - powershell

Question

I am attempting to get a list of installed Drivers and the date they were installed via PowerShell. I have attempted the following:
Get-WmiObject Win32_PnPSignedDriver| select devicename, InstallDate
And the InstallDate property is blank for 100% of the items...
I also tried:
Get-WindowsDriver -Online -All | Sort-Object Date
There is a date there, but it is not the install date. Probably the date the driver was compiled is my assumption.
As a misc note: MMC is not an alternative in this case. Long story.

Answer 1

I found the InstallDate associated with the driver files and not with the driver objects from WMI.
Please find the code bellow for an example:
# Initializing parameters (modify the Output folder by changing the $TargetDirectory define in the first line)
$TargetDirectory = "C:\temp\DriversINFTest\"
$hostname = $ENV:COMPUTERNAME
# Get Third Party drivers used, that are not provided by Microsoft and presumably included in the OS
$drivers = Get-WmiObject Win32_PNPSignedDriver | where {$_.DriverProviderName -ne "Microsoft"}
# Initialize the list of detected driver packages as an array
$DriverFolders = #()
foreach ($d in $drivers) {
# We initialize the list of driver files for each driver
$DriverFiles = #()
# For each driver instance from WMI class Win32_PNPSignedDriver, we compose the related WMI object name from the other WMI driver class, Win32_PNPSignedDriverCIMDataFile
$ModifiedDeviceID = $d.DeviceID -replace "\\", "\\"
$Antecedent = "\\" + $hostname + "\ROOT\cimv2:Win32_PNPSignedDriver.DeviceID=""$ModifiedDeviceID"""
# Get all related driver files for each driver listed in WMI class Win32_PNPSignedDriver
$DriverFiles += Get-WmiObject Win32_PNPSignedDriverCIMDataFile | where {$_.Antecedent -eq $Antecedent}
if ($DriverFiles -ne $null) {
foreach ($i in $DriverFiles) {
# We elliminate double backslashes from the file paths
$path = $i.Dependent.Split("=")[1] -replace '\\\\', '\'
# We elliminate the trailing and ending quotes from the file paths
$path2 = $path.Substring(1,$path.Length-2)
# On the first pass, we only process the INF files as there is a very low chance of existing more than one driver package on the same machine, with the same INF file legth
if ($path2.Split("\\")[$path2.Split("\\").Length-1].split(".")[1] -eq "inf") {
# We get the file attributes for each INF file
$CurrentDeviceID = $d.DeviceID
Write-Host "Current Device ID is $CurrentDeviceID"
$filedetails = $i.Dependent
Write-Host "Current inf file is $filedetails"
$where = $filedetails.split("=")[1]
$query = "select * from CIM_DataFile where Name=$where"
$InstallDate = Get-WmiObject -Namespace "ROOT\CIMV2" -Query $query
$ReadableDate = $InstallDate.ConvertToDateTime($InstallDate.InstallDate)
Write-Host "Installation date is:"
$ReadableDate
} # End of if ($path2.Split("\\")[$path2.Split("\\").Length-1].split(".")[1] -eq "inf")
} # End of foreach ($i in $DriverFiles)
} # End of if ($DriverFiles -ne $null)
} # End of foreach ($d in $drivers)
