# Definir el tipo y versión del SO huésped

Usted puede cambiar el SO huésped con el que debe funcionar una máquina virtual. Debe cambiarlo en los siguientes casos:

* Si actualiza el sistema operativo huésped (por ejemplo, de Windows 10 a Windows 11), deberá cambiar el tipo y la versión del SO huésped, ya que de lo contrario puede que [Parallels Tools](/landing/pdfm-ug/v20-es-es/guia-del-usuario-de-parallels-desktop-para-mac-20/temas-avanzados/instalacion-o-actualizacion-de-parallels-tools/descripcion-de-parallels-tools.md) no funcione correctamente.
* Si usted crea una máquina virtual sin instalar un sistema operativo y más adelante decide usarlo con otro sistema operativo que no es el especificado inicialmente.

Para configurar el tipo y la versión del SO huésped:

1. [Apague la máquina virtual](/landing/pdfm-ug/v20-es-es/guia-del-usuario-de-parallels-desktop-para-mac-20/uso-de-windows-en-su-mac/pasos-iniciales/apagado-o-suspension-de-windows.md).
2. Abra el menú **Acciones** y escoja **Configurar**.
3. Haga clic en **General** y seleccione un SO en el menú que aparece justo debajo del campo **Nombre**.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.parallels.com/landing/pdfm-ug/v20-es-es/guia-del-usuario-de-parallels-desktop-para-mac-20/temas-avanzados/uso-de-maquinas-virtuales/definir-el-tipo-y-version-del-so-huesped.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
