# The Script Monitor Service mentioned is a full Windows Service (for XP & 7) that logs the start and end times of all scripts (vbs, bat, cmd, ps1, etc). The Notepad Scripting Editor can create, edit and run any such scripts in its own command window. Both are available from www.SeaStarDevelopment.Bravehost.com.
