PowerShell – Running scripts is disabled on this system.

Problem:

This error comes when the PowerShell execution policy doesn’t allow to run scripts. I also found the same error when tried to run a PowerShell script.

Solution:

PowerShell execution policy is default set to Restricted. You can change the PowerShell execution policies with Set-ExecutionPolicy cmdlet. To run outside script set policy to RemoteSigned.

PS C:\> Set-ExecutionPolicy RemoteSigned 

Below is the list of four different execution policies in PowerShell

• Restricted – No scripts can be run.
• AllSigned – Only scripts signed by a trusted publisher can be run.
• RemoteSigned – Downloaded scripts must be signed by a trusted publisher.
• Unrestricted – All Windows PowerShell scripts can be run.

You Should Also Know:

You can use get the current set execution policy in PowerShell.

PS C:\> get-executionpolicy 

You can bypass this policy by adding -ExecutionPolicy ByPass when running PowerShell script.

c:\> powershell -ExecutionPolicy ByPass -File script.ps1
