ps1 cannot be loaded because running scripts is disabled on this system

I try to run powershell script from c#.

First i set the ExecutionPolicy to Unrestricted and the script is running now from PowerShell ISE.

Now this is c# my code:

class Program
{
    private static PowerShell ps;
    static void Main(string[] args)
    {
        ps = PowerShell.Create();
        string ps1File = Path.Combine(Environment.CurrentDirectory, "script.ps1");
        ExecuteScript(ps1File);
        Console.ReadLine();
    }

    static void ExecuteScript(string script)
    {
        try
        {
            ps.AddScript(script);
            Collection<PSObject> results = ps.Invoke();
            Console.WriteLine("Output:");
            foreach (var psObject in results)
            {
                Console.WriteLine(psObject);
            }
            Console.WriteLine("Non-terminating errors:");
            foreach (ErrorRecord err in ps.Streams.Error)
            {
                Console.WriteLine(err.ToString());
            }
        }
        catch (RuntimeException ex)
        {
            Console.WriteLine("Terminating error:");
            Console.WriteLine(ex.Message);
        }
    }
}

And the output is:

ps1 cannot be loaded because running scripts is disabled on this system. For more informationm see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170.

The more secure one should be (typed at an admin Powershell terminal):

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

Each case needs a thorough analysis to not expose your system to threats.

RemoteSigned

The default execution policy for Windows server computers.
Scripts can run.
Requires a digital signature from a trusted publisher on scripts and configuration files that are downloaded from the internet which includes email and instant messaging programs.
Doesn't require digital signatures on scripts that are written on the local computer and not downloaded from the internet.
Runs scripts that are downloaded from the internet and not signed, if the scripts are unblocked, such as by using the Unblock-File cmdlet.
Risks running unsigned scripts from sources other than the internet and signed scripts that could be malicious.

Default

Sets the default execution policy.
Restricted for Windows clients.
RemoteSigned for Windows servers.

take a look at all policies

In my case, I needed to allow my azurite (Azure Storage Emulator) script to run, I installed it using npm.

Let me improve this answer with the visuals. I took 3 steps and fixed this problem.

Step #1. I opened Windows PowerShell in admin mode (on windows searchbar search for Windows PowerShell) > right click choose the option Run as administrator. You will be prompted again just click on OK

Step #2 Run this command Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

type Y

Step 3: Close the terminal and move back to where you were previsouly running the command and test it. Like in my case I was having a problem when doing sass -- watch as you can see it now works

This is the best way I've been able to fix it

It is as follows:

First, Open PowerShell with Run as Administrator.
Then, run this command in PowerShell

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
After that type Y and press Enter.
Reopen or Restart
Done! working well!

close your current command prompt or vs code (terminal)
open PowerShell in Admin mode
run this command inside PowerShell

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

answer Y or A (if you want to give access to all users)
now open command prompt or vs code or whatever you like to run your project

For Windows 11 go to

system settings -> Privacy & Security -> Choose For Developers tile under Security -> Scroll down to Powershell.

By default the checkbox is checked. If you want to set that click Apply and it set the execution policy to Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser. Then checkbox and Apply button get disabled.

If you want to change the policy again, need to run the Powershell as an Administrator and execute the desired policy.

Sometimes you may not able to change the policy based on the scope and it might get below error.

For an example if you are try to set to the default policy using Set-ExecutionPolicy -ExecutionPolicy Restricted -Scope LocalMachine you may get

To fix this you may need to follow fix-windows-powershell-updated-your-execution-policy-successfully, but the setting is overridden by a policy defined at a more specific scope or check answers in here. cannot change the Execution Policy

I was getting this error:

 ng : File C:\Users\Nisha Jain\AppData\Roaming\npm\ng.ps1 cannot be loaded 
 because running scripts is disabled on this system. For more        
 information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/? 
 LinkID=135170.
   At line:1 char:1
   + ng serve
   + ~~
    + CategoryInfo          : SecurityError: (:) [], PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess

Just delete this file ng.ps1

   Path is : C:\Users\username\AppData\Roaming\npm\ng.ps1

It works fine for me.

This could be due to the current user having an undefined ExecutionPolicy.

In PowerShell as Administrator, you could try the following:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

Open the windows powershell or cmd and just paste the following command. If it ask for further confirmation just enter YesSet-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

below should appear

`Execution Policy Change

The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose you to the security risks described in the about_Execution_Policies help topic at https:/go.microsoft.com/fwlink/?LinkID=135170. Do you want to change the execution policy? [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "N"): Yes PS C:\Users\Tessact01>`

If you are using visual studio code:

Open terminal
Run the command: Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
Then run the command protractor conf.js

This is related to protractor test script execution related and I faced the same issue and it was resolved like this.

Another solution is Remove ng.ps1 from the directory C:\Users%username%\AppData\Roaming\npm\ and clearing the npm cache

The 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.
