Internet Explorer 9 lets you Pin websites directly to the Taskbar so that you can launch your favorite websites in a single click. To Pin a website to the taskbar, click and drag the Website’s favicon shown in the left of the Address bar onto the Taskbar.

This feature was made possible by introducing new file type [Pinned Site Shortcut] with ".website" extension, which is evident from the Pinned item’s properties.

Pinned Site Shortcut [.website] File Type Association

"Content Type"="application/x-mswebsite"

@="Pinned Site Shortcut"


@="\"C:\\Program Files (x86)\\Internet Explorer\\iexplore.exe\" -w \"%l\" %*"









Note that normal URLs that you see in Favorites menu/bar can’t be Pinned, as was the case in IE8 in Windows 7. It would be nice if the "Pin" feature is added for normal Website shortcuts (.URL files) … so there is no need for a new file type ".website".

    Or after pinning, you can just rename .website to .url and they will still work.

    .website files are essentially plain text. Feel free to open them with Notepad. While .url files are only URLs, .website files are much more than that.

    Make sure you read the recent blog posts at Microsoft has given a good deal of information about this topic. There will be more on the way.

    It is interesting however, that .website files are in fact Microsoft’s implementation of web applications which Firefox and Opera had previously tried to implement.

    @Paultx: That’s not possible. I tried to implement the Pin feature for .URLs, but didn’t work out well..
