USBTeX is a complete, portable LaTeX environment for Windows. It includes portable versions of MikTeX, TeXMaker, Ghostscript, Ghostview, and Sumatra PDF. As the name suggests, you can install it on a USB drive and run it on any Windows machine (provided that you have a decent USB drive). Since LaTeX tends to be “special interest” software, USBTeX could be a very convenient resource.
If this interests you, you may also be interested in using an Online LaTeX Compiler.
