    How to prevent Windows 10 Home 1709 from rebooting automatically?

    Without more detail we can't say.

    What is the cause of the reboot? Is it a BSOD? Or to finish installing an update? Something else?

    By default this happens on EVERY clean installation of Windows 10 Home Fall Creators Update that has internet access, regardless of the hardware used.

    EDIT: %Windir%\System32\MusNotificationUx.exe triggers the event.

    EDIT2: It is to finish installing an update.

    As a temporary workaround, I am using the following commands:
    Code:
    takeown /F MusNotificationUx.exe
    icacls MusNotificationUx.exe /deny Everyone:(X)
    The downside of that is I have to run these commands once more after I manually reboot to let the update installation complete itself. I guess I could put them in a .cmd file and use Task Scheduler to set up a task that runs it automatically at system startup.

    You can set your Active Hours. See this tutorial....

    Active hours lets Windows know when you usually use this device. When a restart is necessary to finish installing an update, Windows won't automatically restart your device during active hours.

    When a restart is scheduled, you can use a custom restart time to temporarily override active hours and schedule a custom time to finish installing the current update(s).
    Change Active Hours for Windows Update in Windows 10


    The 'custom restart time' is greyed out until an update is downloaded and needs a restart. Then you can set a time of your choosing, this can be several days later if you wish. Tutorial here...

    Active Hours are not a real solution that works. That's because I can neither predict what times I will be actively using the system, nor can always accurately predict how long certain processes I will be running on it will take before they are completed, and, due to their nature, some of these processes cannot be paused before a reboot or resumed after it. Specifically, a forced reboot just causes these processes to terminate abnormally, similar to how running into ransomware would also kill the processes, kind of like a bug on a windshield where Windows 10 Home acts like the windshield.

    Further, I am unable to predict that, once an update is downloaded and needs a restart, I will be able to attend the system before Active Hours are over, and, as a matter of fact, Active Hours might already be over even before the update in question is downloaded and needs a restart, as I frequently leave the system actively running unattended for lengthy periods of time in a typical home environment and personal/hobby usage scenario. So please don't tell me I need to pay for an upgrade from Home to Pro to get rid of this ransomware-style behavior of the OS because that simply isn't going to ever happen. Ever.

    No need to get angry.

    Actually, you may not need to upgrade to Pro to take advantage of its feature for deferring updates. Home doesn't offer these in Settings, but others have reported that the registry settings work the same in Home as they do in Pro. See Option Two in this tutorial...

    Windows Update - Defer Feature and Quality Updates in Windows 10

    Of course, an update can only restart the PC after it has downloaded - and cumulative updates or features updates can't download over a metered connection. Set a metered connection, you can then chose a convenient time go into Settings and check for and install updates.

    What makes you think I am angry? That last remark I wrote because I am factually amused.

    Deferral of feature and quality updates does not AFAIK prevent all automatic reboots, as it has no effect on security updates. As far as critical security updates are concerned, AFAIK the same also holds true for metered connections, and, also AFAIK, the same also holds true for setting the Windows Update service to disabled.

    Emotions don't come over well in written text, sorry I misread yours.

    I have studied this carefully. The vaguely worded...

    ...doesn't explain which updates 'are required to keep Windows running smoothly'.

    Since the Creators Update the mysterious wording in Windows Update has puzzled many, and Microsoft hasn't exactly been forthcoming. Just what updates are "required to keep Windows running smoothly"?


    It doesn't help that the behaviour of updates over metered connections was broken with the launch of Anniversary Updates (1607) and has never really worked properly since.

    In 1607 and then in 1703, with metered connections turned on cumulative updates ignore the 'metered' state and try to download anyway, hanging at 2% until you turn off metering. You never got shown the 'Download' button as you should (but you did get asked when the only update was a Defender definitions update).

    Fall Creators Update 1709 seems to have resolved both those issues. Checking for updates over metered connections now appears to work as intended, and it is becoming clear which updates are "required to keep Windows running smoothly". Apparently a Flash security update is too urgent to delay, while a cumulative update can wait for an unmetered connection.

    Since I wrote that I've only seen one other type of update download over a metered connection, updates for the Defender Antimalware Platform (and those don't need a restart).

    I've watched carefully, and seen that Cumulative Updates and Features Updates (these are the ones causing a restart) Defender definitions and other updates like Service Stack updates do NOT download over a metered connection.

    Updates alone may not be the only reason for a restart.

    It may be a BSOD (without a blue screen being shown) as @Bree noted above, and I have seen a restart following an automatic health scan when some disk problem was repaired.

    You might also consider seeing if setting updates to Notify before download works for you with Home. As you don't have the group policy editor (there have been notes posted on how to add that to Home) could try the convenient Windows Update Minitool (free) which includes that option.
