You can also download and install Emacs 21.3 for the various Windows platforms (Win95, Win98, Win2K, WinXP, and so on). As most Windows machines do not ship with the tools required to build Emacs from scratch, we'll look at downloading and installing prebuilt executables.
As with all platforms, you have choices when installing Emacs on Windows. You can install a binary hosted by the FSF (likely to be older, but certainly stable). You can find a more recent binary online (we'll point you to the one we prefer). You could also build Emacs from CVS, but if you're doing that on Windows, chances are you are not reading this book. Windows comes with no default compilers.

This is simply a build of the latest version of GNU Emacs from CVS sources, not a separate version of Emacs as the name may imply. Windows binaries are posted here on a regular basis, giving Windows users access to the latest version without having to build it themselves.
