Missing apps: Store, People, Photos, Games & Camera on upgrading to 10

The title explains it, I did the free upgrade from Windows 8.1 to 10 & all the above apps are nowhere to be found. Not on the alphabetical list or within the Start tiles. I have done searches on this site & on Google, but no luck. Any suggestions please, before I despair & go back to 8.1.

There should be a listing for All Apps at the bottom of the List below File Explorer, and Power.

Thanks for replying spunk. That's the 'alphabetical' list I was referring to, none of these apps are in that 'All apps' list. Any more suggestions?

Go to Start/Search and type CMD, right click the CMD results and Run As Administrator. In the Elevated Command Prompt type SFC /scannow and press enter. This will replace any missing system files.

Hi again spunk,
I did that scan, it returned 'Windows Resource Protection didn't find any integrity violations'. And it didn't solve the problem of the missing default apps/tiles. Thanks anyway for the suggestion!
