<para>With this option enabled DHCP requests will mimic those generated by Microsoft Windows, in
order to reduce the ability to fingerprint and recognize installations. This means DHCP request
sizes will grow and lease data will be more comprehensive than normally, though most of the
requested data is not actually used.</para>
