Good morning.
Every night my Windows 10 PC wakes up, and thus wakes me up, at least once. Event Viewer shows the Wake Source as "Device - ACPI Wake Alarm". This despite my best efforts to disable ACPI wake alarms, and the fact that I can't find any active alarms.
Any tips would be greatly appreciated.
Steps taken:
- In Power Management, I have set wake timers to "Disable"
- In Security and Maintenance, I have ensured "Wake computer" is unchecked.
- In Task Scheduler, I have taken ownership of the relevant UpdateOrchestrator tasks, and unchecked "Wake computer".
- I have used Task Scheduler View to check that there are no tasks with "Wake to Run" checked.
- Running "powercfg /waketimers" shows no active waketimers.
- Running "Get-ScheduledTask | where {$_.settings.waketorun}" in Powershell shows two tasks, both in "Disabled" state.
- Running "powercfg /devicequery wake_armed" shows only the mouse and keyboard.
- I have even reinstalled Windows, just in case something weird was up with the old install.
I have referred to the following sources but after trying all the suggestions I am no closer to a solution

Are you sure there is no mouse/keyboard that wake up the PC? You can use hibernate before the problem is solved. – jw_ – 2020-01-22T06:37:23.980
Take a look at this page

Yes I am sure no mouse/keyboard can wake the PC accidentally. That would show up in the event viewer. Also, hibernate does not solve the problem because ACPI wake alarms wake the PC even in hibernate. When hibernating the PC still wakes me up. :) – Starlionblue – 2020-01-22T13:57:26.257
By "reinstalled Windows", I mean I performed a fresh install. I did not restore a backup. – Starlionblue – 2020-01-22T13:58:00.283
I did check all network cards and disabled their ability to wake the PC. As mentioned in my original post only mouse and keyboard have the ability to wake the PC. – Starlionblue – 2020-01-22T13:59:08.153
spike_66, thanks for the link. However the network card can not wake my system. I unchecked the appropriate box.
As I mentioned, running "powercfg /devicequery wake_armed" shows only the mouse and keyboard. – Starlionblue – 2020-01-23T07:22:42.083

Hi again. I'm still having this issue. This wake timer comes up from time to time. "Timer set by [SERVICE] \Device\HarddiskVolume4\Windows\System32\svchost.exe (SystemEventsBroker) expires at 22:58:30 on 1/02/2020. Reason: Windows will execute 'NT TASK\Microsoft\Windows\UpdateOrchestrator\Universal Orchestrator Start' scheduled task that requested waking the computer." In Task Scheduler it does indeed show "Wake the Computer to run this task." So far I've been unable to change the task even with psexcc. Any ideas? – Starlionblue – 2020-02-01T01:37:53.123
I've now taken ownership of the file and unchecked "Wake the Computer" in the task using psexec. We shall see. – Starlionblue – 2020-02-01T01:43:26.877
Fun wrinkle: If I take ownership of the "Universal Orchestrator Start" file and then remove "Wake the Computer to run this task," Windows creates a new file after a day or two, and then reinstates the task including "Wake..." – Starlionblue – 2020-02-03T03:31:20.183
