# Aclaraciones e información sobre RDP

Comprenda cómo Remote Desktop Manager utiliza el ActiveX RDP de Microsoft (mstscax.dll) frente al cliente FreeRDP integrado para las sesiones RDP.

En Remote Desktop Manager, la última versión de RDP utiliza la última versión del ActiveX RDP de Microsoft presente en el sistema: siempre es **mstscax.dll**, pero la DLL contiene diferentes versiones de la interfaz ActiveX.

FreeRDP es el único cliente RDP que integramos en Remote Desktop Manager, pero solo se utiliza si cambia la versión de RDP a una de las opciones de FreeRDP disponibles. Todas las demás opciones utilizan el ActiveX RDP de Microsoft, que siempre es externo a Remote Desktop Manager

{% hint style="info" %}
Nunca hemos integrado el cliente RDP de Microsoft en Remote Desktop Manager, principalmente porque no es posible redistribuirlo por separado. Todo lo que necesita para estar al día es actualizar Windows, ya que utilizamos la DLL presente en el sistema, sobre la que no tenemos ningún control.
{% endhint %}

En ambos casos, el cliente RDP de Microsoft es externo a Remote Desktop Manager. En condiciones normales, no se espera que se produzca el mecanismo de reserva: si solicita **mstscax.dll**, siempre utilizará **mstscax.dll**; la condición en la que falta **mstscax.dll** no se gestiona.

## 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.devolutions.net/rdm/es/knowledge-base/how-to-articles/rdp-session-entry/rdp-clarification-and-information.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.
