Using PowerShell to control Dell Command | Update for drivers and BIOS updates

The Dell Command | Update is a great tool to use, but it also lacks some features that I have implemented in the following script. During system builds, I have the application to update all drivers and the BIOS. The features I have included are:

1. Ability to disable the BIOS password
2. Ability to either run the dcu-cli.exe on either a 32-bit or 64-bit machine
3. Ability to apply XML policies

For features 1 and 3, if the parameters are not populated, they are skipped over. If option 3 is left blank, it runs the dcu-cli.exe to update all Dell applications, BIOS, and drivers. I know that if you are going to flash the BIOS, the BIOS password is then cleared, but I figured I would add this feature just if you wanted to make sure it was done.

Here is an example of how it is integrated in MDT:

As far as where it is in the task sequences, I placed it within the State Restore and after the first Windows Update sequence.

You can download the script from here.
