But here is what a fonctionné pour moi.
-
Ctrl+Shift+Faites un clic droit sur an empty part of la barre des tâches and clicking "Exit Explorer" (or kill it via Gestionnaire des tâches if that doesn't work).
-
Delete this registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderTypes{ef87b4cb-f2ce-4785-8658-4ca6c63e38c6}\TopViews{00000000-0000-0000-0000-000000000000}
- Start process
Explorer.exe via Gestionnaire des tâches.
