how to update IE..

Yeah, I have to agree with the above posters, I'd recommend Firefox. IE has too many security holes and I really like how Firefox works.

You download only if you have original Microsoft Windows. Don't worry if your windows is genuine otherwise u better don't install it. You can download Internet Explorer from http://www.microsoft.com/windows/products/winfamily/ie/default.mspx There are other good browsers like Mozilla Firefox http://www.mozilla.com and Opera http://www.opera.com

if you want to run IE 7 on your computer than you can only do this if you have an original copy of Micro soft Operating system may be any one of them XP,2ooo,98 etc. if its original and authenticated then only you can have IE 7 on your PC. if you have original OS then you have to simply install it on your PC. it first performs the VALIDATION check and if validated then it installs it on your PC.

updating internet explorer , well i m not sure, but its better to download new version of it.
