What is best LaTeX editor for windows 7? I'm searching for best and perfect editor for Latex based on Windows 7.
As Joseph and Mohammad mentioned, there are quite many possibilities. The one you choose is all a question of taste.
If you use TeX Live, TeXworks comes with it, so it would be easy, to use this one, as you don't have to install anything. But as mentioned, you can use nearly everything, that comes in mind.
Try different ones to find out which one fits best for your needs. The best is always depending one the user ;-)
