Automated Dell Command Update

While working on implementing the new Windows 10 build, I decided to update the Dell Command | Update process. The old script was still looking at the old DCSU and had many inefficiencies that needed to be updated. I also wanted to add new features to the script for logging purposes. With using SAPIEN's PowerShell Studio, the process to update this script was a breeze.

The new script is written so that it can be executed from a command line, build, or a deployment. This now includes the option to write a log file to a specified location by %model%\%ComputerName%. It will delete the old computer name directory and create a new if it already exists. The logs give you the ability to keep track of drivers that may not be applying correctly and you need to inject into SCCM.

Below is how I configured the script in SCCM. The portions I blackened out are the location of the script. It will likely need to be executed as a domain admin account so that it has access to the internet, otherwise you could use the Run PowerShell Script Type.

You can download the script from here.
