# Obtenir Windows auprès du service informatique

Pour que Parallels Desktop puisse fonctionner, vous avez besoin d'une machine virtuelle avec un système d'exploitation (dans la plupart des cas, avec un système Windows) et des applications. Si vous utilisez Parallels Desktop pour Mac Business Edition, l'écran suivant (ou un écran très semblable) s'ouvre au premier démarrage de Parallels Desktop.

Cela signifie que l'administrateur système a préparé une machine virtuelle préconfigurée, avec toutes les applications nécessaires déjà installées. Il ne vous reste plus qu'à la télécharger. Cliquez sur **Télécharger et Installer**, puis suivez les instructions à l'écran. Lorsqu'elle est prête, la machine virtuelle démarre automatiquement et vous pouvez utiliser ses applications.

## 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 following URL with the `ask` and `goal` query parameters:

```
GET https://docs.parallels.com/landing/pdfm-ug/v20-fr-fr/guide-de-lutilisateur-de-parallels-desktop-pour-mac-20/installer-ou-importer-windows/obtenir-windows-aupres-du-service-informatique.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 `build a script that syncs our docs to a CMS` 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.
