Emacs
Emacs is a class of feature-rich text editors, usually characterized by their extensibility. Emacs has, perhaps, more editing commands compared to other editors, numbering over 1,000 commands. It also allows the user to combine these commands into macros to automate work.[1]
Installing Emacs on Windows
This is actually not that hard. Simply uncompress emacs-21.3-fullbin-i386.tar.gz somewhere, and run %somewhere%\bin\addpm.exe. Voila - new icons and start typing. Read the tutorial first - it's a bit tedious, but it will give you a good start. For more details see the directory http://ragnarok.up.ac.za/programdownloads/Emacs; there are a few interesting links there - explore.
For editing LaTeX, just check out http://ragnarok.up.ac.za/programdownloads/Emacs/installingemacsonwindows.html - they are very LaTeX specific. You may find that document better for installing.
Caveat Emptor: Emacs is more suited to knowledgeable computer geeks than normal people. I will make no excuses.
