.SYNOPSIS Show the system summary of the local system or the host behind the PowerShell session. .DESCRIPTION This command will use CIM and Performance Counter as well as some other command line tools to get the current system summary. The summary will displayed in a nice way on the console. .EXAMPLE PS C:\> Show-LauncherPSRemotingWelcome Show the local system summary. .EXAMPLE PS C:\> Show-LauncherPSRemotingWelcome -Session $session Show the system summary of the host behind the session. #> function Show-LauncherPSRemotingWelcome { [CmdletBinding()] [Alias('Show-SystemSummary')] param ( # Optional session to use for the system summary.
