Reinstall Windows Metro Apps
Maybe reinstalling the apps can help solving this problem.I suggest to make a restore point before doing this, in case anything goes wrong.
To remove all apps, open an elevated powershell-console(right click --> run as administrator) and run the following command:
Get-AppxPackage -allusers| Remove-AppxPackage
To reinstall them, open an elevated powershell-console and run the following command:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"
Please Note: Maybe there will be some errors when reinstalling the apps, you can savely ignore them. If reinstall won't work try to get full access to the C:\Program Files\WindowsApps\ Folder as mentioned here: http://winaero.com/blog/how-to-take-ownership-and-get-full-access-to-files-and-folders-in-windows-10/
Also note that a reboot could be required after reinstalling the apps.
Repair corrupt Windows system files
Another option would be to repair windows system files with sfc and dism. To do this, open an elevated command prompt and run the following command:
sfc /scannow
It can take up to 3 runs for sfc to replace all corrupt files. If you still see this error after the 3. run:
Windows Resource Protection found corrupt files but was unable to fix some of them
open an elevated command prompt and run the following command:
DISM /Online /Cleanup-Image /RestoreHealth
Please note: DISM will stay for 5-10 Minutes on 20%. This is a normal behavior. Don't try to stop DISM via CTRL + C or closing the Command Prompt
