My Windows 10 PC randomly wakes up from both sleep and hibernation even though I did not interact with it.
I made sure that no devices are primed for waking up my pc:
powercfg -devicequery wake_armed
and I could disable that easily via device manager and the devices power settings--the issue persisted.
Checking the reason for the last wake, I see:
C:\Users\Philipp>powercfg -lastwake
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.
How can I disable / disallow UpdateOrchestrator\Universal Orchestrator Start to wake my PC from sleep? I only want my PC to wake up when its power button is pressed.
If I have disabled it, how would I check if this setting was still disabled?
I found a setting in the "Security and Maintenance" > "Automatic Maintenance Windows" where it was enabled to: Allow scheduled maintenance to wake up my computer at the scheduled time. Was that the offending setting? (I doubt it as the wake event happens at random times and the setting implies it will only run at 2am).
Listing active wake-timers through an elavated cmd terminal (Win + X > Windows Power Shell (admin) and running:
powercfg -waketimers
still lists an entry:
Timer set by [SERVICE] \Device\HarddiskVolume4\Windows\System32\svchost.exe (SystemEventsBroker) expires at 20:54:15 on 05.03.2020.
Reason: Windows will execute 'NT TASK\Microsoft\Windows\UpdateOrchestrator\Backup Scan' scheduled task that requested waking the computer.
