<p>Here is a workaround :</p>
<ul>
<li>
<p>Cliquez sur le Start or Search icon in the Taskbar</p>
</li>
<li>
<p>Type cmd, faites un clic droit sur Invite de commandes, and puis cliquez sur Run en tant qu’administrateur</p>
</li>
<li>
<p>Copy and paste the following: <code>explorer shell:::{05d7b0f4-2121-4eff-bf6b-ed3f69b894d9}</code></p>
</li>
<li>
<p>Appuyez sur Entrée</p>
</li>
<li>
<p>Select “Always show all icons and notifications on la barre des tâches”</p>
</li>
<li>
<p>Cliquez sur OK</p>
</li>
</ul>
<p>If the checkbox “Always show all icons …” is greyed out, I’m not totally sure what fixed it yet but il apparaît que changing the EnableAutoTray value in the Regedit helped.</p>
<p>To do so, open Regedit, go here:</p>
<pre><code class="lang-auto">[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer]
</code></pre>
<p>Then set EnableAutoTray to 1</p>
<p>It seems this needs to be done on every boot so you could create a shortcut on your Desktop using right-click, New, Shortcut and use the command above.</p>
<p><strong>Update</strong> : at first, I did not like the idea of selecting each app individually using Personalization → Taskbar → “Taskbar corner overflow”, but finalement, it’s not that bad. Whenever there is a new application installed that goes in the overflow, vous pouvez utiliser the Personalization setting to add it. It’s bit annoying but ça fonctionne.</p>
<p><strong>Mise à jour 2022</strong> : please see comment from Grx70 below, as he wrote : vous pouvez drag and drop the icons that are overflowing by selecting them from the popup and moving them onto the tray bar</p>
