You can download IE7 from here

To help customers become more secure and up-to-date, Internet Explorer 7 will be distributed as a high-priority update via Automatic Updates in November.  In addition, Internet Explorer 7 (with protected mode capability) will ship in Windows Vista in 35 languages.

Here are what some people are saying…

“If you've never used anything but Internet Explorer, you won't be able to wipe the grin off your face.”

                David Pogue, NY Times

“IE7 is a monumental improvement over IE6 in both security and functionality. [It] is a solid, feature-packed browser that all IE users should flock to immediately.”

                Paul Thurrott, Windows IT Pro

“I’ve spent the past few days looking at this build of IE7 and can recommend it enthusiastically.”
