# 关于虚拟机

要将 Windows 或其他操作系统添加到您的 Mac，Parallels Desktop 会在您的 Mac 内创建一个“**虚拟机**”或虚拟计算机。然后，您可以在虚拟机中安装 Windows，就像您在常规计算机上安装操作系统一样。

很多人会使用 Parallels Desktop 创建一个虚拟机然后在该虚拟机中安装 Windows。不过，您可以根据需要安装任意多个虚拟机，并在每个虚拟机中安装不同的操作系统。这样一来，您便可以在 Mac 上同时使用多个操作系统。与常规计算机一样，您可以打开和关闭虚拟机、配置虚拟机，也可以安装和使用应用程序。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.parallels.cn/pdfm-20-ug-zh_cn/parallels-desktop-for-mac-20-yong-hu-zhi-nan/gao-ji-zhu-ti/shi-yong-xu-ni-ji/guan-yu-xu-ni-ji.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
