Internet Explorer 7

Internet Explorer 7 shipped as the default browser for Windows Vista and Windows Server 2008 and was made available for Windows XP with Service Pack 2 or 3 and Windows Server 2003 with Service Pack 1 or 2. Internet Explorer 7 discontinued support for Windows 2000 or earlier with Microsoft citing required security API improvements that were not available in prior systems. While attempts have been made to get it working in 2000, these have proven unsuccessful so far.

This version introduced tabbed browsing to allow browsing multiple webpages in one window.
