Skype likely uses the standard Windows components for its embedded browser which means Internet Explorer.  Apps that embed browsers is a good reason to always ensure that Windows is fully up to date and you&#x27;re not using an outdated version of Windows like XP or Vista which can&#x27;t run an updated copy of IE11 (the current release).  It&#x27;s similar to the issue on older versions of Android that used the outdated browser component of the host operating system within apps... which was nearly always out of date and insecure on US carrier-branded handsets.
