Windows PowerShell is a shell initially developed by Microsoft for task automation and configuration management. There’s no wonder that its Execution Policy is set to Restricted, which protects from running malicious scripts. If you’d like to sign the script and solve this, here are a few methods that may help.
How do I make a PowerShell script digitally signed?
1. Check and change the Execution Policy
The first thing to do if your PowerShell script is not digitally signed is to change your Execution. This removes the restrictions preventing your script from running and lets you run all types of scripts.
2. Bypass the current PowerShell session
Another quick fix for the PowerShell script file is not digitally signed issue is to set the execution policy to bypass the current PowerShell session. Even better, these settings will be lost once you close this PowerShell session.
3. Unblock the file that was downloaded
When the Execution Policy is RemoteSigned, this requires that all scripts and configuration files downloaded from the Internet or emails are signed by a trusted publisher. If you trust the script’s contents are safe, you can unblock it to run on your session. The easiest way to do this is to use the Unblock-File cmdlet, as shown above. There you have it. With the three solutions in this guide, you should be able to get rid of the PowerShell script not digitally signed error.
