The Advanced Schedule options dialog is accessed from the Run When tab of the Macro Properties window.  Options are:

When Repeating

These options are used when you have set a repeat interval on the main schedule.  The default option is repeat continuously.  What this means is that even after the system restarts the schedule will continue to repeat (as long as the current day is a day chosen in the main schedule).  The second option will tell Macro Scheduler not to keep repeating continuously, but only to repeat until the specified time.  At that point the original schedule time is reset to the original start time.

Recovery

Here there are three options.  The default is to do nothing except run the macro at the scheduled start time, as normal.   If the second option is set, then when Macro Scheduler restarts it checks to see if a macro should have run on that day.  If a macro was supposed to  run on that day and at a time prior to the system restarting, the macro will be run immediately.  The third option will simply allow you to run the macro on startup regardless.  Note that the third option will not effect the schedule time in any way - it simply runs the macro.

Scheduler Service

If you have enabled the AutoLogon service in options to schedule your macros when Windows is locked/logged out you can determine whether this macro should be started by the AutoLogon service here.  Uncheck Allow Scheduler Service to Run this Macro if you do not want the AutoLogon service to start this macro when Windows is locked/logged out.  This option has no effect if the AutoLogon service is not enabled in Options.
