1)I recommend you not to replace explorer.exe since it is harmful but still I have included it separately for people who want
to change their explorer.
2)Please make backup of the original files before copying these.
3)Create a restore point before installing these.
4)Do this in SAFE MODE(Not compulsory,but for a safer result).
5)This is a Vista-only package.This was made using Vista Home Premium but I think it should work on the other versions.
6)Dont try this if you have upgraded to SP1.
7)Please dont copy IE if you have installed IE 8.
