windows-10

All windows Apps stop working. When you try to open any windows 8 or windows 10 App it will open, show up start App Screen and then close. I was able to see the app on my “Taskbar”. I tried all the solutions given on different forums. i.e ran system file checker, tried system app troubleshooter. nothing worked for me.

Reason
One of the applicaiton installation or virus or malware changed some permissions to the App store and apps.

Solution

  1. Open Registry Editor using regedit.exe.
  2. Right click on HKEY_CLASSES_ROOT.
  3. Click on “Permissions” and in popup click on “Add”.
  4. In 2nd Popup click on “Advanced”.
  5. In 3rd Popus click on “Find Now”.
  6. In “Search Results” click on “All Application Packages” and then click “Ok”.
  7. Now in 2nd Popup “Select Users or Groups” click again “Ok”.
  8. In Permissions select under Allow “Read” and Click “Ok”.
  9. Close the Registry Editor. No need to restart.

All Apps Would be working. It worked for me perfectly.
