Lite Touch

OSD – Export drivers using a task sequence in Lite Touch and some PowerShell

Yesterday i did a demo of a Task Sequence I use to extract drivers from a computer that already have all drivers correctly installed, could be a system that I need to reinstall, or a new machine with fairly new drivers installed. The Task Sequence basically grabs information from the computer, such as Operating System, Architecture and Model or Modelalias, grabs the drivers and copy them to the deployment share. I can then import the drivers to a ConfigMgr package or use them in LiteTouch for deployment.

The script is fairly simple and easy to change to fit in your environment.

The Task Sequence

It contains 3 steps, a gather step to get the inventory of the machine correctly, a set finish action to avoid reboot if your are using finish action in customsettings.ini and the application that grabs the drivers. Since it is a application this task sequence works only when Windows is running, not in WinPE.

The Task Sequence.

The Application

The Script runs as an application, so you need to download the script to a folder and then import it as an application with following settings:

PowerShell.exe -ExecutionPolicy Bypass -File ExportDrivers.ps1

The Extract Drivers Application in Deployment Workbench.

The Script

The PowerShell script is a generic script I use a s “wrapper”, so it does have functions that is not really needed in this scenario, so it is possible to make it shorter if you for any reason want that. The script detects if it has been invoked from a task sequence or not, if it has, it will create a path based on deployment root, Operating System, Architecture and ModelAlias (If you don’t use ModelAlias UserExit, start to do that or change to Model in the script), otherwise it will export the drivers to C:\ExportedDrivers

The active part of the script looks like this:

Note that it will delete all drivers that begins with PRN. That is printer drivers and I usually do not want them.

  1. Could you elaborate on the “a set finish action to avoid reboot if your are using finish action in customsettings.ini”, how is this compiled in the task sequence?

  2. When the script runs on a test computer I get “The term ‘Export-WindowsDriver’ is not recognised as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

  3. #Export Drivers
    Export-WindowsDriver -Destination $Path -Online -Verbose

    I think that won’t work in Windows 7 SP1 since it is not a command available for that OS.
