A couple of days ago most apps on my surface pro will not launch. When I try the screen just goes a navy blue and will stay like that until I tap on the screen, then it just goes back to the start screen. I have shut down numerous time but it doesn't help. The other accounts seem to work fine. Does anyone have any suggestions on things I can try? Is there a way I can reset my profile without having to I re-install my apps?? I have tried searching Google but nothing relates. Thanks.
