And to do scheduled tasks without using the GUI, do the following (it seems to be more reliable)
at 05:00 /INTERACTIVE /every:T,Th,S,Su "c:\stuff\newapp.bat" /switchfornewapp
The time is 24 hour.
/Interactive allows it to be run on the desktop vs. in the background if you need to do it that way.
/every is the days it runs on.
I put all of my tasks in a batch file like so:
rem start by clearing jobs
at /delete /yes
rem Run such and such program one
at 01:00 /INTERACTIVE /every:T,W,Th,F,S,Su "C:\Filename" /switch1 /switch2
rem Run such and such program two
at 02:00 /INTERACTIVE /every:T,W,Th,F,S,Su "C:\Filename2" /switch1
The jobs stay after reboots, so to make changes you have to clear them all out. I just put the batch file in my startup folder and that way it makes sure it's always right. Also, I can just make a quick edit and rerun the batch file and it makes it consistent again by clearing all and recreating the jobs.
