| === Find Classes and Properties ===
| |
| | |
| In order to find the correct class use...
| |
| <pre>
| |
| Get-WMIObject -list -credential $cred -computer 159.104.224.167 | Select-String -InputObject {$_.Name} Win32*
| |
| </pre>
| |
| | |
| 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)...
| |
| <pre>
| |
| Get-WMIObject Win32_BIOS | Format-List *
| |
| </pre>
