Internet Explorer 7

Internet Explorer 7 shipped as the default browser for Windows Vista and was made available for Windows XP with Service Pack 2 or 3. Internet Explorer 7 discontinued support for Windows 2000 or earlier with Microsoft citing required security API improvements that were not available in prior systems. Attempts to get it working in 2000 have not succeeded.

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