Utility to switch system between a Graphical User
Interface (GUI) and Server Core mode
A PowerShell module DellTools.psm1 is located in C:\Dell_OEM\PSModule folder, installed in the factory to assist you with common
tasks. The module includes a function that allows you to configure your system in a Server with a GUI mode and then convert to Server
Core mode and place the system in production. Also, it can be used to switch back to GUI for configuration and troubleshooting.
The detailed steps on using this add-in are provided in the readme file at C:\Dell_OEM\PSModule in your system.
For security reasons, PowerShell script execution policy is set to restricted by default and must be modified to allow scripts to run on the
system. It is recommended to set the execution policy back to restricted after completing your scripts. For more information about how
to change the execution policy, see the article Set-ExecutionPolicy at technet.microsoft.com or other related articles at
support.microsoft.com.
