== Credentials ==
When running commands that require a connection to a remote machine its useful to be able to store a user/pass combination so that you aren't repeatedly prompted every time you run a command.  Create a credential object, then supply that in place of a username in a command
 
<pre>
PS H:\> $cred = Get-Credential
 
cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Credential
PS H:\> Get-WMIObject -query "SELECT * FROM Win32_OperatingSystem" -credential $cred -computer 159.104.224.167

=== 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>
