I run this as an application towards the end of the TS then reboot with MDT and run it again followed by another reboot before finishing up the whole TS.

@echo off
TITLE Running DELL Command Update...
REM Checks for updated DELL Drivers using DELL Command Update CLI

"C:\Program Files\Dell\CommandUpdate\dcu-cli.exe" /configure -silent -autoSuspendBitLocker=enable -userConsent=disable
"C:\Program Files\Dell\CommandUpdate\dcu-cli.exe" /scan -outputLog=C:\dell\logs\scan.log
"C:\Program Files\Dell\CommandUpdate\dcu-cli.exe" /applyUpdates -reboot=disable -outputLog=C:\dell\logs\applyUpdates.log

It's pretty self explanatory but it configures it first, does a scan, then applies the updates and disables reboot so that MDT can do it instead. I run this against DCU 4.1.

I don't recommend silencing the Apply Updates stage (it isn't in that script above) because sometimes it can take a little while and not being able to see what it's doing can be nerve racking.

Update: Not sure if this was recent but you must now remove the (x86) out of the Program Files path (maybe they made the app x64 now?)

Here's a script I made that works really well. Of course you can tailor it for a GPO but standalone, it works wonders.

The gist is.. it will check if Dell Command Update is installed and if it is, it will run it and install all available updates. If it's not installed, it will look for the Dell Command Update msi and silently install it and then run it silently. If it cannot find the msi automatically, it will prompt you with an explorer GUI to browse to the .msi and silently install/run it.

Esentially.. a single click to do all Dell updates. It's also turning off Dell automatic update (handy for enterprise/small business) but you can delete/comment that out. In order to get the .msi you can run the Dell Command Update tool and in the middle of it running, you can find it in the Windows temp directory and copy it out of their and put it on a network share or USB stick for mass deployment.

Bending Dell Command Update 3.1 To Your Will
March 11, 2024 - You could deploy DCU 3.1 within Product Provisioning in one cohesive design, which I would strongly recommend (that just requires adding in the DellCommandUpdateApp_Setup.exe file and then adding the run command for DellCommandUpdateApp_Setup.exe /S /v/qn OR you can deploy the application via the Intelligent Hub and set the product to elective/optional. At a minimum, I will show you how to prepare the DCU 3.1 installer so you can deploy, but if you want help with actually deploying it reach out to me. Building the package is pretty simple, but not a ton of info on it out there. First, you will go here and download the universal package for DCU 3.1 and then run a single command in CMD to extract the installer for deployments:

DELL Command Update version: Dell-Command-Update-Application-for-Windows-10_GRVPK_WIN_4.3.0_A00.EXE

Dell Command | Update Version 4.x Reference Guide

Steps:

  1. Open interactive command line interface on remote workstation
  2. Execute dcu-cli.exe /applyUpdates -updateType=bios,firmware,driver -autoSuspendBitLocker=enable -outputLog=C:\Temp\scanOutput.log
  3. Command fails with return code 500 (see log output below)

I’ve omitted all commands except /applyUpdates -updateType, but I am still getting the same result.

I can ping downloads.dell.com and dellupdater.dell.com.

I’ve attempted this on different workstations over several days.

Any help would be appreciated.
