I Want To return to originalExplorer6

All you need to do is to remove the program and reload the Explorer 6. I didn't like the 7 version at first but now I find it has many features that I like and prefer it over 6.

See How to uninstall Internet Explorer 7. Another option is installing Firefox or another browser. Eventually, expect the Windows Update site and perhaps others to require IE7 or later. Leaving IE7 installed may save you a reinstall later.
