# Dell Command Update

## Overview

{% hint style="info" %}
**Dev Insight:** This script was originally written to make sure devices deployed during our MDT process had the latest drivers/firmware from Dell, but it can also be used to update Dell devices already deployed via your RMM of choice.
{% endhint %}

This script downloads and installs the latest version of Dell Command Update (DCU) if not already installed. It will then use `dcu-cli.exe` to download and install all Dell driver/firmware updates, ignoring reboots.

**Prerequisites:** This script has no prerequisites.&#x20;

**Notes:**

* Script will abort if a PC manufacturer other than Dell is detected.
* Dell Update, which is incompatible with Dell Command Update, will be removed if detected.
* .NET Desktop Runtime, a prerequisite to Dell Command Update 5.5+, will be updated / installed to the latest LTS release if not already installed.&#x20;
* Dell Command Update is not intended for use with server hardware. Use Dell System Update instead.
