I had this problem when I first installed Windows 10. I was successful when I followed these instructions:
1.) Right click on start menu select Command Prompt (Admin)
2.) Type powershell and press enter
3.) Once powershell is loaded, enter this:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
4.) Restart
I've recently realized after installing Windows 10 that I did not have any updates installed so I would suggest trying that as well.
