# What Versions of Windows You Can Install

There is a difference in supported versions of Windows between Apple Silicon Macs and Intel Macs:

* For Apple Silicon Macs, Parallels Desktop 20 supports installing versions of Windows 11 Pro and Enterprise Editions designed for running on Arm processors.
* If you install Parallels Desktop 20 on a Mac with an Intel processor, you can run any editions of Windows 10 and 11.

This guide primarily focuses on using Parallels Desktop 20 to run Windows 11, with mention of Windows 10 where applicable.

{% hint style="info" %}
**Note**: On Intel Macs, you can technically install any other older version of Windows (8, 7, Vista, or even XP), but it is not guaranteed to work smoothly in any situation, and you may need to install an older version of Parallels Tools, as described in [this KB article](https://kb.parallels.com/129252).

## 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.com/landing/pdfm-ug/v20-en-us/parallels-desktop-for-mac-20-users-guide/readme/what-versions-of-windows-you-can-install.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.
