<p>I have no idea why or what I have broken in the process.<br>
But here is what worked for me.</p>
<ul>
<li></li>
</ul>
<p>Ctrl+Shift+Faites un clic droit on an empty part of the taskbar and clicking “Exit Explorer” (or kill it via Gestionnaire des tâches if that doesn’t work).</p>
<ul>
<li></li>
</ul>
<p>Delete this clé de registre.</p>
<p>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderTypes{ef87b4cb-f2ce-4785-8658-4ca6c63e38c6}\TopViews{00000000-0000-0000-0000-000000000000}</p>
<ul>
<li>Start process <code>Explorer.exe</code> via Gestionnaire des tâches.</li>
</ul>
