What is currently the resource-rich language (or languages) considered simpler to install on Windows?

Question

(Another off-topic face question for the collection)

Installing development environments for programming languages is not always easy. Java and Ruby, for example, are languages that in my experience for you to be able to run some useful code take a certain amount of work.

This is particularly true in Windows, where they do not usually come installed and where there is no (at least not historically) one package manager included.

What would be the language (or languages) in which this effort is reduced to the minimum, in the case of Windows? I’m not even talking about IDE, I’m just talking about having a compiler/interpreter to run on the same command line.

Under Linux is easier. It is common to already come the gcc (C), gpp (C++) and Python installed in popular distros, among other less used distros one-Liners, as awk and sed.

I am considering powerful and expressive languages, shell script does not count.

I think the easiest thing to come is the Javascript that comes in any browser for any system. Already to have in the command line must give a little more work, I know that the NPM is a package manager popularly used for its dependencies but never installed to know how complicated it is.

I’m thinking of languages that serve both desktop programming and web programming. Python for example could be a great candidate if it is easy to install on this system.

The more popular the better, but if you have some not so popular at the tip of the language take advantage and share there too.
