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
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 SystemDirectory : C:\WINDOWS\system32 Organization : TF BuildNumber : 3790 RegisteredUser : TF SerialNumber : 69712-640-3560061-45009 Version : 5.2.3790

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 *
