<p>The following link describes how to change this behaviour in Windows 8 using a registry setting and some permissions on that registry setting. It also works with Windows 10.</p>

<p>First launch le registre editor: Press <code>WIN + R</code>, type <code>regedit</code> et cliquez sur “OK”.</p>
<p>Naviguez vers the following path:</p>
<blockquote></blockquote>
<p><code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\UserSwitch</code></p>
<p>Change value of the key <code>Enabled</code> from <code>0</code> to <code>1</code></p>
<p>There’s one more problem to solve: The user <em>SYSTEM</em> automatically changes the value to <code>0</code>. So we will disallow the user <em>SYSTEM</em> to change it.</p>
<ul>
<li>
<p>Right mouse click at registry key <code>UserSwitch</code> → <code>Permissions</code></p>
</li>
<li>
<p>Cliquez sur <code>Advanced</code> and then on the <code>Disable inheritance</code>-button; if your are prompted with two options now, choose the first one (<em>Convert inherited permissions into explicit ones for this object</em>)</p>
</li>
<li>
<p>At the top of the dialog, change the owner from <em>SYSTEM</em> to the group <em>Administrators</em> (if your Windows is not in English, the name might differ a bit, e.g. in German it would be “<em>Administratoren</em>”)</p>
</li>
<li>
<p>Select the group <em>Administrators</em> entry → Allow → full control</p>
</li>
<li>
<p>Double-cliquez sur the entry for <em>SYSTEM</em>, select type <code>Deny</code> and cliquez sur <code>Show advanced permissions</code>. Here <code>Clear all</code> → only check <code>Set value</code></p>
</li>
</ul>
