SCCM Task Sequence Remove Video Drivers

During my project to upgrade all our Windows 7 Enterprise SP1 (64bit) devices to Windows 10 Enterprise 1809 (64bit), I ran into a compatibility issue during the task sequence. Windows 7 video drivers were detected as incompatible during the in-place upgrade to Windows 10, so I had to find a way to remove the drivers during the SCCM task sequence.

This is the batch file code I used to disable, then remove video drivers from the task sequence.

@ECHO OFF

REM Driver is disabled
devcon disable =display

REM Driver is removed here
devcon remove =display

REM reg add command replaces whatever value is in the SearchOrderConfig with the appropriate value to tell the system NOT to go to windows update for driver updates
REG ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\DriverSearching /t REG_DWORD /v SearchOrderConfig /d 0x0 /f

REM Driver package is removed here
FOR /F “tokens=4 delims= ” %%A IN (‘devcon driverfiles ^=display ^| FINDSTR “Driver installed from”‘) DO devcon.exe dp_delete -f %%A

EXIT 0

The following shows where in the task sequence I add the video driver removal step. Also, note that I have a step to copy devcon.exe utility which is not on Windows 7 by default.

I’ve extensively tested this on my DELL devices and it works perfectly.

Run PowerShell Script in Schedule Tasks

The following will allow you to run a Powershell script as a scheduled task. These instructions have been tested on a Windows 7 64bit computer.

Before proceeding, make sure your Powershell script runs without any errors. The best way to make sure your script is running fine is by calling it from a command prompt.

Note: Make sure you run Set-ExecutionPolicy from an elevated Powershell window to make sure your system (Windows 7) is allowed to run Powershell scripts.

  1. Open a Command Prompt window
  2. Run: powershell -file <your ps script file>
  3. Make sure it executes properly

 

Now, open Windows 7 Task Scheduler:

  1. In the Actions tab
  2. Power shell is found at: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
    1. You can also just use powershell.exe
  3. In Add arguments (optional) field, add the following: -File “C:\Path-to-your-script\Your-ps-script.ps1”
    1. Sample: -File “C:\Program Files (x86)\Info Folder\Get-Speed.ps1”
  4. In Start in (optional) field, add the following: C:\Program Files (x86)\Info Folder
    1. Sample: C:\Program Files (x86)\Info Folder

I’m not going to go over the other sections as this is the main section to be able to execute Powershell scripts from Schedule Tasks.
