Internet Explorer (IE) is Microsoft's browser, which has been known to win the first browser war over Netscape, by bundling it with Windows.

In IE7 on Windows XP the bookmarks are placed by default in "c:\Documents and Settings\<username>\Favorites". This is the folder that needs to be included in a backup if necessary.
