After hours of troubleshooting 100% disk usage on my Inspiron 15 5000 I narrowed it down to Dell software.  Unfortunately the prime suspect DCFWinService exists as a process but there is no such named service showing up in the service list.  I can stop the process but cannot disable the service.  So I removed all Dell programs through control panel and that cured the problem.  I would like you to tell me what if any risks or problems I may have after removing all the troublesome Dell (pardon me but it's true) - bloatware.  

Thank you.
