I'm using Windows Server 2008 R2
I'd like to schedule to run a particular process at 40 minutes on hourly basis, except on Sunday at 2:40AM.
How would one set up the trigger for this in Task Scheduler?
Set up multiple triggers in Windows Scheduler. One "Weekly" trigger recurring for 6 Days. A second "Weekly" trigger (Sunday), which will repeat its task every hour for a duration of 23 hours (you don't have to use the pre-defined times, just type new ones into the field). Set start times accordingly to meet your requirements.
