usoclient.exe in Windows 10 wakes up my PC with Wake Source: Unknown
 So for a few weeks now, I've been dismissing this new Windows 10 Creators Update nag dialog.  Some days I wake up to find that my PC is already awake.  It turns out that Microsoft's been doing something sneaky behind the scenes.  I thought I'd done all the usual methods to prevent that scenario, such as disabling the mouse from being able to wake up Windows.  Looking in Event Viewer (eventvwr), I see the wake source is Unknown.           We can run a command in Windows Powershell to list all Scheduled Tasks that could wake the PC:    Windows PowerShell Copyright (C) 2015 Microsoft Corporation. All rights reserved.
