I would suggest you to refresh Windows 8 and then check if this fixes the issue.
Follow the steps:
a. Press “Windows Key + w”.
b. Type “Refresh” in the search box and hit “Enter”.
c. Select “Get started” option under “Refresh your PC without affecting your files” section.
d. Follow the on-screen instructions.
Important: Refreshing Windows 8 will remove all third party applications installed and it will reset all the Microsoft applications to default.
