my windows apps(store,maps,sports,video,mail etc) are not opening(it will give an error message 

that"the application cant start"),please what can i do???it is saying something about the cache 

being damaged.

 Try running the Apps troubleshooter

Reset Windows Store cache   1. Press Windows key + R. 2. Type wsreset.exe.Press Enter.  

Reset the cache, have a look at this : http://arnavsharma.net/3/post/2014/11/-reset-windows-store-cache-using-wsresetexe.html

Hello,

In addition to previously made suggestions, you can also try to re-register all apps at once:

Let us know if something worked for you.

Hope this helps, Good luck :)

Hi Waleshi,

Would you mind show us the error screenshot here?

If the error message is related with Windows Store cache, you may follow the suggestions to type wsreset.exe.

And if it won't work, try to re-register the apps:

Open CMD with admin rights, then copy and paste the command below:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml

Restart Windows Store and check the issue again.

Best regards
