Being a user of Windows 8.1, one day you may face the problem due to failure of the work of contemporary (Modern) apps. For example, applications can open and then close. It may be that after appearing on the start screen saver application ceases to show any signs of life. The same fate may befall even a system app, but luckily there is a simple and fast procedure, which can help you to return to normal.

Step 3: Now press Enter to start the process and wait for its completion.
Step 4: Restart the computer.
