Found a better answer on technet:
Simple: cliquez sur le "hide" box only in Desktop folder
(In Windows Classic view,) allez dans Explorateur Windows; cliquez sur Desktop. Allez dans Tools/Options des dossiers. Click View, et cochez "Hide protected operating system files" - but, DO NOT CLICK "APPLY TO ALL FOLDERS". Just cliquez sur OK. Now, only the Desktop folder will hide the files but they will still show up in all other folders.
