@r.c.,thank you for sharing your configuration. Your system is a very clean canvas, & one among our staff, @Umbra Polaris, would be very pleased to add a new pupil to his "Sith Master" teachings. 50% j/k.. He is truly good (and quite knowledgeable ...just don't tell him) Lol!
I'd like to offer a software called CCleaner. Read about, & safely download here. http://www.softpedia.com/get/Security/Secure-cleaning/CCleaner.shtml You can also extract it onto an external (stick) flash drive in keeping with your system's state of being light & free!
