Windows installations are incomplete

Similar to #2151.

https://doc.rust-lang.org/book/ch01-01-installation.html#installing-rustup-on-windows documents:

On Windows, go to https://www.rust-lang.org/tools/install and follow the instructions for installing Rust. At some point in the installation, you’ll receive a message explaining that you’ll also need the C++ build tools for Visual Studio 2013 or later. The easiest way to acquire the build tools is to install Build Tools for Visual Studio 2019. The tools are in the Other Tools and Frameworks section.

This is correct, but not the full story: Just installing the build tools does not install link.exe and further down expose people to the "linker not found" issue. The recommended way is to actively check the box for "C++ tools". I'm not sure if this is the best way to get link.exe, as it installs 1GB of C++ frameworks along with it.

Hmm, are you sure? Has this changed or something recently?

I feel like this has changed... so maybe these instructions shouldn't be in the book, but should be in rustup's documentation/error messages?

I set up a new computer today, the only thing you need to check is the "C++ build tools". check that box, and you get all this

that's what's described in the paragraph, and it works, so I'm gonna close this. @skade if you have some objection please let me know!
