How can I obtain the driver key for an installed device?

Question

Unfortunately this Question was asked 4 years ago but no answer yet How can I obtain the driver key for a driver programmatically?

actually if it was answered, I would not ask again.

I have a software depends on Naps2 scanner software. I want to generate profiles.xml file and it depends on Driver Key and DeviceName

profiles.xml like below:

<?xml version="1.0"?>

after searching windows devices I found that the Driver Key {6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0000 is in here:

What I need is a PowerShell script or one-line script that gives me a Driver Key like "{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0000" with zeros or any number depending on how much scanners are connected to the machine (NOT Class GUID only {6BDD1FC6-810F-11D0-BEC7-08002BE2092F}), and Device Name like below:

Get-WmiObject Win32_PNPEntity | Where-Object { $_.PNPCLass -eq "Image"} | select *

Or

Get-WmiObject Win32_PnPSignedDriver | Where-Object { $_.PNPCLass -eq "Image" } | select *

Thanks in advance

Removing all the stuff from my first response (if you kept that, it may be useful later to you) and coming back to what Abraham Zinala pointed you to and tweak it to get the value you are after.

# Using WMI

Point of note: Not all known cmdlets are available on all PS versions/OS platforms.

I use my custom function to get such info dynamically as needed.

Answer 2

I guess what you're after is the Class GUID. You also tagged Posh 2/3/4.0 but, using Get-CIMInstance is the way to go: introduced in Powershell 3.0 - Get-CIMInstance - gives you the same functionality of Get-WMIObject without as much security concerns.

Get-CimInstance -Namespace root/cimv2 -ClassName Win32_PNPEntity | Where-Object PNPClass -EQ "Image" | Select-Object -ExpandProperty ClassGuid

Also, try to include the -Namespace parameter. It tends to query the objects faster even though the Get-CIMInstance cmdlet is pointed to the Root of the namespace; must be doing something under the hood.
