This has happened to me on my windows 8 machine, I did a little searching and found that the entire windows 8 needed an update, to update windows 8 open the charm bar (on touch slide finger in from right, with mouse put it in top right corner) once the charm bar is open look at the bottom and select "Settings", in settings go to the bottom and hit the "Change PC settings" button, once this menu opens on the right panel select "Windows Update", if there is a update click the update button, but if it displays no update hit the "Check for updates now" button. If all else fails you can refresh your pc, refreshing your pc will keep all your personal items like files music and such, to refresh your pc, navigate to the PC settings (You should already be here) and in the right panel select "general" scroll down in the General settings until you find the "Refresh your PC without affecting your files" then hit the "get started" button. Hope this helped!
