As such, IE has been completely rebuilt. It's no longer integrated with the Windows Explorer shell to improve security.
Version 7 will add tabbed browsing, one of the most popular options in competitors such as Firefox, along with anti-spoofing and anti-phishing protection, a search box with a number of search engines to choose from, and support for RSS feeds.
Another big change will be the addition of new Web technologies that have emerged since IE 6 came out five years ago, notably Cascading Style Sheets (CSS) 2.1.
Microsoft said in a statement announcing the release that more than 200 behavioral changes have been made to CSS between beta 3 and RC 1.

Other enhancements include a simpler user interface, customizable search box and a revision to how favorites are organized.
