Section on Editing the pip.ini File on Windows Needs to Be Updated

In "Further Configuration of pip and Virtualenv" (/dev/pip-virtualenv) the Windows section doesn't seem to work (I'm using Windows 10).

One's home directory would be something like:
C:\Users\johndoe

But you won't find pip in this folder. Instead, you'll find pip at a path something like:
C:\python37\Lib\site-packages\pip

(BTW, I used the guide recommended method of installing python [choco])

In addition, I'd suggest breaking this section into two parts, one dealing with *nix systems and one with Windows systems. Right now they are kind of intertwined.

If what I have suggested above is amenable, I'm happy to make a pull request with the edits I'm suggesting.

从 /dev/pip-virtualenv 中的“Further Configuration of pip and Virtualenv”部分开始，并根据报告的 Windows 10 布局检查其中关于 Windows pip.ini 的说明。验证正确的平台特定路径，并将 *nix 和 Windows 的说明分开；当两个部分都组织清晰且 Windows 说明准确时，即视为完成。
