        .DESCRIPTION
            This function examines the list of winlogon process and compares them to active sessions.
            If a winlogon process belongs to an active session, it is left alone.  If it is not tied
            to an active session, it is removed.  The console session is specifically ignored, since it
            always has a winlogon process, even though there may not be someone logged into the physical
            console of the machine.

#Requires -Module Citrix.Broker.Admin.V2

function Remove-BadWinLogonSession {
    <#
        .DESCRIPTION
            This function searches for sessions that are in a NoApps state (Applications Not Running) and
            also do not have a BrokeringUserName.  This state indicates a session with a hung winlogon.exe
            process that is not "owned" by anyone.  Sessions in a NoApps state, but have a BrokeringUserName
            are valid inactive sessions and are not modified.

    <#
    .SYNOPSIS
        This tests for multiple sources in multiple eventlogs
    
    .DESCRIPTION
        This works regardless of if it exists directly in registry or not.
        This is different than the Test-EventSource which uses a dotnet function 
        to check for all the sources that are directly listed in the registry.
