Vous pouvez quickly and easily change it:
Click View in the menu of Explorateur de fichiers
Click Options at the right side of the ribbon, then Change folder and search options (or simply cliquez sur le icon above Options)
In the dropdown menu next to Open Explorateur de fichiers to: select This PC
Cliquez sur OK.
J'ai aussi like the "Quick access" view so I'm not so sure if Je veux permanently set "This PC" to the default view when the explorer is opened
In that case you have two options:
Get used to simply clicking Quick access in the navigation pane of Explorateur de fichiers
Pin Quick access to the menu Démarrer and assign a custom raccourci clavier to it:
Faites un clic droit sur Quick access in Explorateur de fichiers et cliquez sur Pin to Start
Faites un clic droit sur Quick access in the menu Démarrer et cliquez sur Open file location
Faites un clic droit sur the shortcut for Quick access et cliquez sur Properties
Assign a raccourci clavier
As for raccourci claviers, vous pouvez assign shortcuts of the following forms:
If you only press a letter, then the first form is automatically used.
If you select a raccourci clavier that is used for other purposes (such as F1), then your shortcut will either not work, or the functionality of F1 will be overridden by your shortcut.
