In my installation, it's in the ecrypto package, which may not be part
of the default install from the Windows installer.  Try running the
installer again and do a custom install, maybe?

Unless you're basically happy with no packages at all, I think it's
very risky to use a partial install of packages.  There are just too
many obscure dependencies, and many libraries developed primarily in a
GNU Emacs environment will assume that everything in the world is
available, and just die if anything it wants is missing.  (Remember,
that's how a bare (require 'feature) works.)
