This article contains some of the worst computer advice I've read recently! Clearing the clutter on your all apps screen by deleting program shortcuts from the underlying start menu folders is really stupid. What if you want to run one of the affected programs at some later date? The shortcuts you will have deleted would come in handy then. It is not always that simple to figure out where that shortcut pointed to later.
This is the ALL APPS screen we're talking about after all. It is supposed to be comprehensive. The better option is to clean up the Start Screen instead. Uninstall or Unpin all of the tiles you don't want and then look for things on the All Apps screen you do want and pin them to the Start Screen. Voila! Your All Apps screen is intact and you have a nice, clean custom Start Screen.
