Why don't my apps start after I updated?

[WPCentral Question]

Apps dont start after update

When I open my metro apps on windows 10, app like Groove, mail, store, most apps don't start, is there any help I can get with this
Can't use most of my metro-apps again after installing updates.

I'm dealing with the same thing. Did a clean install via the Win 10 ISO and still have the problem. Store, Photos and several other apps will not open yet others like Mail, Calendar, and Grove do launch. Have tried several suggested solutions from a number of message boards including Microsoft's but so far nothing has worked.
