I downloaded version 20201029 and when I go to edit a previously scheduled task, update and reboot cycle is no longer in the list. I also do not see it in the list of tasks under Windows Update anymore.
The update reboot cycle was deprecated a few years ago. We finally removed it from the software in this most recent release. Please use the job queue instead. It’s much more powerful and flexible. You can create a custom job queue called “update reboot cycle” if you want. Then just use that in your task.
