Update November 2 = Just to let you know, I have a workaround in place that is working well. SCCM Package deployments lets you reschedule the running of the program (dcu-cli.exe" /applyUpdates -autoSuspendBitLocker=enable -silent -reboot=enable) which runs just fine whether a user is logged on or not plus I can set the deployment to only run when No user is logged on so I can reboot the computer (-reboot=enable) when an update requires a reboot. We have a very robust update subscription service at our University where we create all kinds of different ways updates are installed. For example, for the Dell Command Update, we have a Manual subscription, 2 Weekly subscriptions (AM or PM) and a Monthly subscription (AM or PM). I was originally trying to use the scheduling feature built into the DCU (/configure -scheduleWeekly=Sat,03:00) but no matter what schedule or time I used, the Dell update service for the DCU never starts. The Service.log and the GUI show I am setting the schedule correctly yet it never starts. The only time the DCU works on a schedule is when it is left as the default where it runs every 3 days.scarneol
I am unable to get the DCU to work using the -scheduleWeekly  or -scheduleMonthly option plus I am also having trouble with notifications and the -ScheduledReboot option as well. I am able to apply all of the settings properly using the /Configure command and all the -options yet the scan never kicks off at the scheduled time. I see some odd messages in the Service.log even when a user is logged on to the computer. DEBUG} No user is logged on, notifications should not be sent DEBUG} Ignoring and removing this scheduled auto update event because notifications cannot be displayed DEBUG} Enable the remind me later schedule, beginning at one hour from now DEBUG} Update the remind me later schedule to 10/23/2020 2:00:30 PM The DCU works fine if I manually kick it off: dcu-cli.exe /applyUpdates but there are no notifications ever, even when using the -scheduledReboot=5,15 or 60 and the only way to get the computer to reboot is using: dcu-cli.exe /applyUpdates -reboot=enable which forces the computer to reboot immediately.
DCU 3.1.3 (Schedule and Scheduled Reboot do not work)
