LGP Startup/Shutdown Script
Author: Zinthose (talk, contrib) |
UNSTABLE RELEASE | This release is in development and should not be used in a production environment. |
Origin
I needed to deploy the nVidia driver update to the systems within my company. To make the process as painless as possible, I wanted the process to run before the user logs into the system as the install requires a reboot. By using the Local Group Policy Scripting service, we are able to perform the update without forcing the user to log on twice due to reboot. This also further prevents the user from interrupting the update.
Purpose
Intended for use in cooperate environments with a deployment system like Symantec's Altiris or Microsoft's System Management Servers.
!! Caution !!
The scripts need to be removed after execution. This has the potential to enter a continuous reboot cycle if installing software that reboots after completion but fails to remove the LGP Script entry. If you get into this situation, you will need to boot the system into safe mode and remove the entries manually. Removal can be done by modifying the Registry and the script.ini files manually, running a previously generated "removal" NSI script, or using the GPEdit.msc utility.
DO NOT ATTEMPT TO USE THIS IF YOU DON'T UNDERSTAND WHAT THE LOCAL GROUP POLICY SCRIPTS ARE AND DO.
USE AT YOUR OWN RISK!
Functions

Code
Eample
The following example demonstrates how to add Notepad to the system startup and shutdown. Not exactly useful but meh.. it was simple and shows how it executes before logon and after shutdown.
