<p>This is almost too trivial to make a PR but I'm no expert in Win32 COM and maybe I missed something (or the original author just missed something).</p>

<p>According to the <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/bb762115%28v=vs.85%29.aspx">MSDN docs</a>:</p>

<blockquote>
<p>It is the responsibility of the calling application to call CoTaskMemFree to free the IDList returned by SHBrowseForFolder when it is no longer needed.</p>
