This is a great reason to stay connected on Facebook, because your friends ask questions and their friends can also answer them who you are not connected to. This was a FREE piece of technology I didn’t know about for keeping my computer systems optimized.  (In non-tech speak that means, it allows your computer to go a little faster, clean up old useless files, and organize it better. )  The FREE version of Advance System Care 3 doesn’t allow for scheduling the software to automatically do it, so schedule yourself weekly to click their icon.  It’s a no brainer.
