<pre>
PS H:\> $cred = Get-Credential
 
cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Credential

</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>
