What if PowerShell is not digitally signed? How to Fix PowerShell not digitally signed?

If the PowerShell script is used from other sources or the internet and the trusted publisher does not sign, it means it gives an error like the PowerShell script is not signed digitally, or the execution of the script is disabled in the system. Powershell has implemented many in-built security features.

PowerShell not digitally signed Error

In simple terms, to fix this error, change the settings of the script to remote signed or all signed or unrestricted. The restricted mode in the execution policy of PowerShell avoids the execution of scripts to follow safety measures.

So use an unrestricted execution policy to solve the script that is not signed. It is an easy method to fix the error like PowerShell is not signed digitally and change the execution policy of the local system to unrestricted.

The user can opt to bypass the execution policy to fix the script that throws a digitally-not signed error.

The temporary method in bypass execution policy is blocked; if the user tries to execute the script, it doesn’t give any prompt or warning for confirmation. So using the bypass policy, the script is executed temporarily but with minimal security.

Execute the .ps1 file script with minimal security, and once it is done, close the session of PowerShell and bypass with itself.

The PowerShell script file should be unblocked. In the cmdlet, PowerShell unblocks – file should be given to unblock all the files or scripts downloaded from cyberspace. By default, these files are restricted to protect the system, and if the user makes it to trust all these scripts by unblocking – the file command, he can unrestrict to execute it in the PowerShell session. So it is one of the methods to solve the error file that is digitally not signed.

PowerShell is not digitally signed Methods

The software in the local system manages the drivers up and running to ensure the system’s safety and protect it from common hardware failure and computer errors.

So if the user gets any errors, check all the drivers using the below steps:

1. Driver Configuration

Download the verified file to driver fix.

Choose a start scan that detects all the problematic drivers.

Give update drivers to install the new version that avoids system malfunctions.

2. Configuration of Execution Policies

Once this is done, go for the execution policies and how they can be rectified to fix the issue.

Execute Get – execution policy in the cmdlet to fetch the execution policy that lists all the parameters and policies for every scope.

According to the user’s convenience, change the execution policy to set the execution policy in cmdlet using the below command and change it to unrestricted. C: Set –execution policy unrestricted. They give Y to confirm the prompted changes. Ensure that the change in policies is updated in the registry and remains the same unless it is changed for the next time. If the user executes an unsigned script, it asks for permission before it starts to work, and that permission can also be changed.

3. Bypass Option

The other method is to execute the below command that bypasses the existing PowerShell session.

When the PowerShell session is quit, these settings will be lost and needs to be configured again.

4. Unblocking Method

When the execution policy is signed remotely, it needs all the configured files that are used from the internet or mail to be a trusted source. So if the user gives it as a trusted one, he can give the below command to make it unblock and executed in the system.


Hence these are the few methods to fix the digitally-not signed error. Hence it termed the feature of PowerShell execution policy to load configuration and execute scripts that prevent malicious attacks.
