How to Ensure Your PowerShell Script Continues After a Reboot

When automating tasks with PowerShell, encountering a problem where the script does not continue after a system reboot can be quite frustrating. This problem is especially common when setting up new laptops or performing installations where you need the system to restart for changes to take effect. In this guide, we’ll explore the issue in-depth and walk you through a solution that allows your script to resume successfully after a reboot.

Understanding the Problem

You’ve written a PowerShell script that performs several tasks, including renaming a computer, restarting it, and installing software. However, after the reboot, the script does not automatically resume from where it left off. This typically happens because the script hasn’t been set to execute automatically after the system boots up again.

Let’s break down the solution step-by-step.

Step 1: Prepare Your Initial Script

To ensure your script executes properly after a reboot, you can use the RunOnce registry key. This is a method that allows you to set a command to be run once the system starts up after a reboot. Here’s how you can implement it in your script:

Example Command

Key Points

AutoAdminLogon: Automatically logs in to the admin account after reboot, which allows your script to run.

RunOnce registry key: It allows you to specify a command that runs at the next startup.

Step 2: Create the Script to Run After Restart

Now that we’ve set the initial script, we will create a second script that will execute once the machine has rebooted. This script should handle any further installations or configurations needed.

Key Points

This script logs information about the reboot into a text file, installs the required software silently, and removes the stored credentials to ensure security.

Final Thoughts

Although working with scripts can come with certain challenges, following these steps ensures that your PowerShell script will continue running after a reboot. Do remember that storing passwords in plain text is not secure, so consider implementing a more secure mechanism when handling sensitive information.

That’s it! You are now equipped to handle PowerShell scripts that require continuity post-reboot effectively. If you have any questions or need further clarification on certain steps, feel free to reach out!
