I was tired of always updating SCCM with new Dell driver packages. Some were getting as many as 15 new enterprise cabs over the deployment life. Then I discovered Dell Command|Update (DCU). Here’s what happened:
We had tried installing DCU during the OSD task sequence, but found that the software was throwing alerts to the logged in user that software was not up to date. We were certain that would generate calls to the service desk. Configuring it to not do that was kind of a chore. Uninstalling it at the end of the Task Sequence seemed counterproductive.
As I studied DCU some more, I found that:
- it has useful command line options,
- the application and its support files didn’t need to be any particular location,
- creating the required service so DCU could run was trivial,
- it was going to be a fun scripting project
- Download DCU (from here) and install it on a test PC.
- Next copy the application and service folders (“C:\Program Files (x86)\Dell\CommandUpdate” and “C:\Program Files (x86)\Dell\UpdateService”) to the SCCM source folder. I placed “UpdateService” folder inside “CommandUpdate” folder as seen below.
- Create the batch script that will be the brains of the SCCM Package (see below). In this example it’s called update.cmd and it’s saved in the above mentioned SCCM source folder.

- The CMD file understands 4 arguments (Lines 27 – 30) : Driver, Application, BIOS and All. If you create them as an SCCM package, you’ll have up to 4 programs, each with one of the above respective arguments. You can deploy them via Software Center or, with some modifications, GPO or whatever else you might have.
