If you want to display the English desktop, you must add the language. Clic on Ajouter une langue (Add laguage).
You need to find the English tile. Double-clic on it or clic on Ouvrir.
Clic on the language. Clic Ajouter (add).
You then need to select English (Canada) and click on Move up. The change will apply at the next logon.
Clic on Paramètres avancés (Advances settings).
Select Anglais (Canada) as a default entry method. Clique Enregistrer (Save)
You can now clic on the right-top X to close the window. Logoff (Fermer le session). On your next logon, your desk will be in English.
