I am a big fan of CCleaner and have been using for years with no issues. They just introduced a new Driver Updater which I tried. It caused my touch screen to stop working. I immediately reversed everything but the touch screen still wont work. I wrote to them and they asked me to send them a bunch of reports which I immediately did. No response. I have written multiple times with no response. My expensive Dell XPS which i paid extra to have a touchscreen is now useless, all thanks to this terrible "Driver Updater" and poor customer service. Too bad that a good company can introduce a product that hurts customers and then won't fix it.
