Find Classes and Properties

In order to find the correct class use...

Get-WMIObject -list -credential $cred -computer 159.104.224.167 | Select-String -InputObject {$_.Name} Win32*

To then see all the properties of a class use (doesn't work on remote machines (access denied) - this is a known bug in Power Shell v1)...

Get-WMIObject Win32_BIOS | Format-List *
