Microsoft drops support for features in Metro IE 10

Microsoft drops support for features in Metro IE 10 Affects: IE10 Metro Microsoft has dropped support for some legacy IE-only features in IE10 (Metro version) in Windows 8 (due out later this year). Two methods in particular have been dropped: showModalDialog() and showModelessDialog(). Example:
<script type="text/javascript">
 var legacyModalPopup = showModalDialog(url, args, options);
 var legacyModelessPopup = showModelessDialog(url, args, options);
However that's far from the complete list! Microsoft is also dropping support for common JavaScript features like: MS Pinned Sites, addBehavior, window.print(), window.prompt(),, window.external, onhashchange event, onoffline event, ononline event, AddSearchProvider(), AddToFavoritesBar(), and yes even window.alert(), window.confirm(), navigator.codeName, and of course there is no ActiveXObject support in IE10 Metro.
Known Workarounds: None.
