There is indeed a simple menu item you can click during the personalizing of the Start 8 settings, in order to de-activate the charms bar as well as the interactive Windows 8 corners -- at least there was on the trial version i downloaded.  This was the principle reason I tried the software, and it worked fine, i even turned it on and off just to make sure.  Then,  i went back to change some other settings, including the one that opens a pop-up menu listing of apps, when you right click on the start button: when I did this, it de-selected the repression of the charms bar, and now i am stuck with that thing popping up all the time again.  i downloaded the purchased program, and now cannot find the control panel, for adjusting these settings.
