I have a problem with my windows 8.1. Yesterday I bought my new laptop that had 8.1. already installed. When i set everything up it was working fine, but today i turned the computer on and the start display was not working. when i want to open an app from start it won't work. I tried to switch users and it worked just fine, so the only problem was wit my account. I don't know what to do. English is not my first language so i hope that everything was clear.
