Apps / Software :: Win 8.1 - Metro Apps Crash To Desktop Or Don't Operate Correctly

I initially created the thread below but I have since discovered the problem relates to many apps and not just the People app.

People App Opens then Crashes to Desktop

I have a new Dell laptop running Windows 8.1 Core Edition. After only a week I found most of the apps would crash to the Desktop on opening. I thought I had solved the problem by creating a new user account and reinstalling the apps but that only worked for a week before the same problem reappeared.

This is what I have discovered to date:

Initially most apps crashed on openingReinstalling the apps made many of them work but there are still some issues e.g. selecting Maps within Bing weather causes the app to crashThe apps work fine in a new user account or in other local accounts I have not used much to dateNone of the steps recommended in Apps and Tiles Not Working or Responding: Fix in Windows 8 solves the problemI've spent an hour with Microsoft Support who have found no obvious problem and have escalated the problem to the next tier

The problem appears to be due to access rights and priveliges in user accounts since the apps work in other accounts or if I create a new account.

Where the apps are located for each user account and whether there is way of checking that they are set up to have the correct access rights and privileges.
