We recently did a slow release by installing Dell Command Update in new images (so not directly from Intune) and configuring it to update itself via the Intune ADMX. So right now, only about 5% of devices have Dell Command Update. We have it configured to update once per month.

How has it worked for you? Do you have any horror stories? Do you have any config recommendations?

We utilize PatchMyPC and this morning, it updated "Dell Command | Update" to v5.6.0. Our OSD task sequences install DCU, apply a config file for DCU, then invoke the CLI to apply any driver/firmware updates it finds. For us, this is simpler than updating the driver packages for each model all the time and ensures that a system is running the latest patches and is ready for use as soon as the task sequence completes.

I tested an OSD task sequence on a Dell workstation to validate the new version. DCU installs successfully, I'm able to apply the config file, but when it runs the "dcu-cli.exe" command, it fails immediately and returns 3006. That specific return code is not documented, but 3000-3005 all indicate issues with the Dell Client Management Service. Looking into the logs, I can see smsts.log showing the following output from dcu-cli.exe:

Currently the system is in Windows Out of Box Experience (OOBE) State. Please try again after sometime.

Applying Dell updates via DCU at this stage of OS provisioning has never given us problems before, so I can only assume it's something that changed in this update. To confirm, I rolled back the version of DCU used in the task sequence to 5.5.0 and observed the failure was no longer present.

Not sure if this issue is expected going forward and is the "new normal" (which would be disappointing) or if it's unintentional. Regardless, I figured I'd share here in case anyone else was experiencing this and had any suggestions.

The main page for Dell Command | Update (currently) is located here: Dell Command | Update | Dell US

However, for the past couple of days, if you click on the links to download DCU 5.5 that are on this page, which are:
Dell Command | Update Windows Universal Application

Dell Command | Update Application (Classic)

Both of those links take you to a page that says it's unavailable:

Searching for it on support, you can only get 5.4 from any of the Drivers & Downloads pages, even for brand new machines.

Was it pulled? We've deployed and used it hundreds of times since April, not sure why it's gone, and what's going on?

Edit: Found a direct download link, that's gone too:
