Try any of the following possible solutions:
1) Open an elevated command prompt by typing "CMD" into Start, right-clicking Command Prompt, and selecting "Run as Administrator." Enter "sfc /scannow".
Restart after the scan is over and see if it helped. If no change occurs, then open another elevated command prompt and enter: "Dism /Online /Cleanup-Image /RestoreHealth".
2) Open up an elevated PowerShell prompt by typing "PowerShell" in start, right-clicking on the first option, and selecting "Run as administrator." Inside the prompt, paste the following:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
