In Vista, I would like to schedule a task (bat program with shutdown command)
that runs weekly (Sun-Sat). It should start at 11:00 PM, run every 1 minute
for 8 hours. The task (batch job) should not run from 7:01AM-10:59PM.

I was able to set the scheduled task using XP; however, under Vista the task
keeps on running after the 8 hours.

Thanks
