I have the EXACT same problem. I can't do a reset or anything similar because I have programs that I only have one licence for that will not nork anymore when I get all programs deinstalled. So Microfost better fix this, because I need this PC working for my thesis. (Only, I seem to be able to open the store, but can't access the settings because I can't swipe up. it just won't work.)
Also, I noticed someone here had advanced systemcare, and so have I. Never had problems with it on my Win 7 PC, but maybe it's part of the culprit now? How many people here have Advanced Systemcare?
