Windows 10: PC wakes at night

With powercfg /lastwake I found this source:

Wake History Count - 1

Wake History [0]

Wake Source Count - 1

Wake Source [0]

Type: Wake Timer

Owner: [SERVICE] \Device\HarddiskVolume4\Windows\System32\svchost.exe (SystemEventsBroker)

Owner Supplied Reason: Windows will execute 'NT TASK\Microsoft\Windows\UpdateOrchestrator\Universal Orchestrator Start' scheduled task that requested waking the computer.


I opened the TaskScheduler in admin mode and found the task - my problem is, when I uncheck the "wake computer to run task" part, I have to type in some password - my log in password nor my microsoft account password work - I get this message:

An error has occured for task Universal Orchestrator Start. Error message: The following error was reported. The supplied variant structure contains invalid data.

I can also select different usernames from a drop down:

S-1-5-18

User DT

App Prefetched Info

(the mail adress associated with my microsoft account)

3c251c4...

And two more entries that aren't even users and for which I can't enter a password

Can't stop machine waking itself from hibernation


My desktop machine keeps waking itself up from hibernation, usually during the night, despite my having taken all reasonable steps to stop it. I have:

• disabled waking on network, mouse and RTC in BIOS setup
• disabled wake on mouse and network in device manager (and checked with powercfg -devicequery wake_armed)
• disabled "allow wake timers" for all power plans

It doesn't however wake itself up from S5 (shutdown). I also tried leaving it in S3 sleep for over 24 hours and it didn't wake up, although that's not long enough to be certain that it never would.

Unfortunately my records in Event Viewer only go back a bit over a week to my upgrade to Windows 10, but I did notice a pattern in the first few days of waking at around 00:17 or 00:18 in the morning. Event Viewer suggested that this was due to mcupdate_scheduler, which was scheduled to run at 00:19, so I changed the trigger (following some instructions from Microsoft), but the next night the machine woke earlier, at 23:45. Unfortunately event viewer had no idea what caused that particular event. And today I have just run powercfg -waketimer and apparently there is a task \blah\blah\updateorchestrator\reboot which requires waking the machine just after 02:00 tomorrow morning. Clearly trying to change each individual trigger is a hopeless game of whack-a-mole which will sooner or later result in my wrecking something. How on earth can I stop my machine waking up?

 

Windows 10 PC wakes up randomly in the night

Please see:

If the Wake Source says “Power Button,” that indicates that the power button on the PC was pressed to wake it up—an action you most likely took yourself.

If the Wake Source says something like “Device–HID-Compliant Mouse (or Keyboard),” that indicates the PC is configured for key presses and mouse movements to wake it.

If the Wake Source lists your network adapter, that indicates your PC is configured so that incoming network activity can wake it up—something that’s useful if you like having your PC go to sleep but still need it available to other network devices at times.

If the Wake Source says “Timer,” it means that a scheduled task woke the computer. The source information usually includes some indication about the task that woke the PC. For example, in the previous screenshot, I can tell that my PC was woken up in order
to do a scheduled restart after an update.

You may also see something like “Wake Source: Unknown,” which is a bit more cryptic but at least it tells when the PC was awoken.
