Listing Bios settings using Windows PowerShell

I have a Hp Pavilion g6 laptop running Windows 10 Pro and I would like to list all (or as much) bios setting as I can from within windows without actually going into the bios for debugging purposes. I searched online and I was able to find this PowerShell line

Get-WmiObject -Namespace root/hp/instrumentedBIOS -Class hp_biosEnumeration |Format-Table Name,Value -AutoSize

but it gives me this error

Get-WmiObject : Invalid namespace "root/hp/instrumentedBIOS" At line:1 char:1 + Get-WmiObject -Namespace root/hp/instrumentedBIOS -Class hp_biosEnume ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (:) [Get-WmiObject], ManagementException + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

and i don't know where to go from here

If you are happy to use a third party program you could try RWEverything.

Below are three methods to find BIOS information from inside Windows.

BIOS via PowerShell

To use get all information related to the BIOS:

Get-WmiObject -Class Win32_BIOS

The above command will give a small subset of properties of the Win32_BIOS class. To list all the properties use this:

Get-WmiObject -Class Win32_BIOS | Format-List *

Other classes are:

CIM_BIOSElement
CIM_BIOSFeature
CIM_BIOSFeaturedBIOSElements
CIM_BIOSLoadedlnNV
CIM_VideoBIOSElemnt
CIM_VideoBIOSFeatureVideoBIOSElements
Win32_SMBIOSMemory
Class Win32_SystemBIOS

BIOS via wmic

The command:

wmic bios list full

May give the following details:

BIOS via the registry

The BIOS info is in the key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\BIOS.
