IE7 has been released by Microsoft. It has a lot of bug fixes, but the next question is do you dare to upgrade? I suggest that you should look at the Release Note first before upgrading. You can get the files from Microsoft Download or from MajorGeeks.
For my own laptop/PC, i don't want to rush in by installing this update, as it's one of the biggest upgrade on Windows and IE is one of the vital component on Windows platform, so if something bad happened, you will have unstable system, so i would wait for public review first before i decided to upgrade to the latest IE. For now, i'm quite satisfied with Firefox which will release 2.0 version in a short time (the latest version now is 2.0 RC3).
