Note that Windows should handle such abrupt interruptions gracefully (after all power losses are much worse and happen all the time) but if you are paranoid about your system's stability you may wish to avoid the 'murder'. If it still fails you may want to disable the service (don't forget to re-enable it) and then kill the related processes.
Once again if you get an error like 'The service could not be stopped' you should retry a couple of times. Please retry once or twice if stopping any of them fails The CLI Commands You need to stop these 2 or 3 services: ' Windows Update', ' Background Intelligent Transfer' and (for Windows 10 only) ' Delivery Optimization'
