I have no touchscreens, nor, on my budget, is it likely in the future, but I have several Metro Apps installed, which I use comfortably with the usual mouse gestures.
Whatever. The point is that a GUI removal tool might be the easier way to go than possibly delete something that might be needed.CCleaner is a free reg cleaner
