If the command didn't solve the problem, the try these steps in order:

1. Disable superfetch service
   • Empty the following folder c:\Windows\Prefetch\
   • Restart the computer
   • Si ça ne marche pas, passer à l'étape 2;
2. Disable the AppXSvc from the registry: change the "Start" key value from 3 to 4 (see the screenshot)
