.SYNOPSIS Get the core performance counter and system information for the PowerShell Remoting launcher welcome screen. .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 be returned as a PowerShell object. .EXAMPLE PS C:\> Get-LauncherPSRemotingWelcome Get the system summary of the local system. .EXAMPLE PS C:\> Get-LauncherPSRemotingWelcome -Session $session Get the system summary of the system behind the session. #> function Get-LauncherPSRemotingWelcome { [CmdletBinding()] param ( # Optional session to use for the system summary.
