Windows 10 wakes itself up to install updates

I recently upgraded my home desktop computer to Windows 10. Ever since I've done this, my computer has been waking itself up from sleep at seemingly random times during the night. This is incredibly annoying since I sleep in the same room as my computer and it wakes me up at 3:00AM.

After some research, it appears as though it is waking itself up to automatically install updates.

I've tried several things to disable this.

• Go to "Power Options" in the control panel. Change plan settings. Change advanced power settings. "Sleep"/"Allow Wake Timers" is "Disabled".




• I've used powercfg -devicedisablewake to disable all devices so that powercfg -devicequery wake_armed returns NONE.




• Wake on LAN is disabled on my motherboard.




• In "Windows Update Settings", under advanced options, I've switched from "Automatic" to "Notify to schedule restart".




• Finally, based on this Reddit thread, I've opened "Task Scheduler", gone to Microsoft/Windows/UpdateOrchestrator/Reboot, opened Properties and then the Conditions tab, and unchecked "Wake computer to run this task".

I thought the problem was finally solved after I turned off "Wake computer to run this task" in the reboot task for UpdateOrchestrator (the last bullet above). That seemed to solve the problem for several days. But then it happened again last night. When I looked today, the "Wake computer to run this task" option was checked again in Task Scheduler. I think the setting might have changed itself when I manually ran Windows updates a day or two ago.

This is driving me mad. How do I prevent my computer from waking itself up from sleep?
