    Wake from sleep with segmentation fault

    My computer frequently wakes up from sleep all by itself.
    The following looks suspicious:
    C:\Users\rw>powercfg /lastwake
    Wake History Count - 1
    Wake History [0]
    Wake Source Count - 1
    Wake Source [0]
    Type: Wake Timer
    Owner: [SERVICE] \Device\HarddiskVolume2\Windows\System32\svchost.e xe (SystemEventsBroker)
    Owner Supplied Reason: Windows will execute 'NT TASK\Microsoft\Windows\UpdateOrchestrator\Reboot' scheduled task that requested waking the computer.
    (The italics makes backslashes look like pipes)
    It is interesting that the very same command executed from a cygwin
    bash prompt gives a different response:
    $ powercfg /lastwake
    Wake History Count - 1
    Wake History [0]
    Wake Source Count - 1
    Wake Source [0]
    Type: Wake Timer
    Owner: Segmentation fault
    I don't know that this is due to Windows 10, but it does seem to have
    started when I did the upgrade from 7.
    A possibly related symptom is that sometimes when I manually turn on
    my computer from sleep, it reboots rather than simply waking up.
    Can someone help me understand this behavior?

    This post seems to have a fix.

    If waking from sleep re-starts, maybe you shutdown instead of sleeping? In Event Manager the last shutdown reason should be shown.

    cheers, Paul

    Thanks for the link, Paul.
    I turned off "Allow wake timers" in "Power Options" yesterday,
    but it was running again this morning. Logs show a lot of activity
    occurring this morning after 3:00.
    So I disabled "Enabling Windows Update Power Management to automatically wake up"
    in the Local Group Policy editor (it was Not Configured), and we'll see what happens tomorrow.

    Re: waking from sleep restarting: When chrome complains that it had been shut
    down improperly, I think the evidence is that I had never shutdown.
