<p>In case you are using the Skype App, removing the context menu item is trickier.</p>
<p>One way is to delete <code>DllPath</code> under</p>
<pre><code class="lang-auto">HKEY_CLASSES_ROOT\PackagedCom\Package\Microsoft.SkypeApp_15.61.100.0_x86__kzf8qxf38zg5c\Class{776DBC8D-7347-478C-8D71-791E12EF49D8}
</code></pre>
<p>However updates to the app will probably restore this. Adding the following <code>REG_SZ</code> key</p>
<p><code>"{776DBC8D-7347-478C-8D71-791E12EF49D8}"="Skype"</code></p>
<p>to</p>
<p><code>[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked]</code></p>
<p>is probably a good idea. Restart Windows to take effect.</p>
