It seems not too long ago that Microsoft released IE 7.0. That was on October 18, 2006.Not being very impressed with the new version, til date I'm still using IE 6.0 SP2. You may probably have come across website incompatibilities with the newer versions of IEs, reason being some of the websites are still not updated to work with newer versions of browsers.
IE 8.0 RC1 was officially released on 26th January 2009, boasting of many new security features.

Alternatively if you're anti IE, you can grab a copy of Firefox 3.0 here.
