- Author: Carter Roeser
- Last Updated: 2024-03-12
- Please ensure PowerShell Execution Policy allows script execution and that all paths and dependencies are correctly configured in your environment.
- Designed to be used in an MECM task sequence, where automation of driver installation is crucial. Will fail if the Task Sequence Environment COM object is not available.
- Make sure to adjust the script paths and environment variables according to your specific deployment environment.
