TeX software for Windows

LyX (styled as ''''''; pronounced ) is an open source, graphical user interface document processor based on the LaTeX typesetting system. Unlike most word processors, which follow the WYSIWYG ("what you see is what you get") paradigm, LyX has a WYSIWYM ("what you see is what you mean") approach, where what shows up on the screen roughly depicts the semantic structure of the page and is only an approximation of the document produced by TeX.

MiKTeX is a free and open-source distribution of the TeX/LaTeX typesetting system compatible with Linux, MacOS, and Windows. It also contains a set of related programs. MiKTeX provides the tools necessary to prepare documents using the TeX/LaTeX markup language, as well as a simple TeX editor, TeXworks. The name comes from the login credentials of the chief developer Christian Schenk, MiK for Micro-Kid.
