IE7 available for download
Yesterday, October 19th, Microsoft released their new IE7. It can be downloaded from the IE7 site. After you download the file, close all running programs incl. IE. Disable your antivirus program. Stay online and do not turn off your firewall. A best practice seems to be to reboot TWICE after the installation.
You can also wait until IE7 comes down through the automatic update next month.
