How to enable execution of PowerShell scripts?












198














When I try to execute my PowerShell script I get this error:




File C:CommonScriptshello.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details.

At line:1 char:13

+ .hello.ps1 <<<<

          1. Start Windows PowerShell with the "Run as Administrator" option. Only members of the Administrators group on the computer can change the execution policy.



          2. Enable running unsigned scripts by entering:



            set-executionpolicy remotesigned



          This will allow running unsigned scripts that you write on your local computer and signed
          scripts from Internet.



          See also Running Scripts at Microsoft TechNet Library.

            +1 for remotesigned instead of unrestricted. You can run your local scripts without exposing yourself to dangers from everywhere else.

            Is there a way to enable execution of a specific powershell script? So perhaps I just want to allow hello.ps1 from the OP, or Microsoft.PowerShell_profile.ps1 on a user's box? (I think that arguably falls under the admittedly broad OP question (ha, which I now see is also yours!). If you feel that's a new question, though, I can ask it.)

          The Default Execution Policy is set to restricted, you can see it by typing:



          Get-ExecutionPolicy


          You should type the following to make it go to unrestricted mode:



          Set-ExecutionPolicy unrestricted


          Hope this helps

            The requiring signing make sense if you expect the user to copy&paste malicious scripts from the internet. If you assume the user isn't stupid, then "remotesigned" doesn't add any security and makes life difficult.

          On my machine that I use to dev scripts, I will use -unrestricted as above. When deploying my scripts however, to an end user machine, I will just call powershell with the -executionpolicy switch:



          powershell.exe -noprofile -executionpolicy bypass -file .script.ps1

          We can get the status of current ExecutionPolicy by the command below:



          Get-ExecutionPolicy;


          By default it is Restricted. To allow the execution of PowerShell Scripts we need to set this ExecutionPolicy either as Bypass or Unrestricted.



          We can set the policy for Current User as Bypass or Unrestricted by using any of the below PowerShell command:



          Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass -Force;

          Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted -Force;


          Unrestricted policy loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the Internet, you are prompted for permission before it runs.



          Whereas in Bypass policy, nothing is blocked and there are no warnings or prompts during script execution. Bypass ExecutionPolicy is more relaxed than Unrestricted.

            Depending on the Windows version and configuration, you may have the following warning, even in Unrestricted mode:




            Security warning
            Run only scripts that you trust. While scripts from the internet can be useful, this
            script can potentially harm your computer. If you trust this script, use the
            Unblock-File cmdlet to allow the script to run without this warning message.
            Do you want to run?
            [D] Do not run [R] Run once [S] Suspend [?] Help (default is "D")



            The solution is to use the "bypass" policy, enabled with the following command:



            Set-ExecutionPolicy Bypass


            From the documentation:




            Bypass: Nothing is blocked and there are no warnings or prompts.




            This is obviously insecure, please understand the risks involved.

            A reg key with:

            Windows Registry Editor Version 5.00




            [HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsPowerShell]
            "EnableScripts"=dword:00000001 "ExecutionPolicy"="Bypass"




            and:



            Windows Registry Editor Version 5.00

            [HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsPowerShell]
            "EnableScripts"=dword:00000001 "ExecutionPolicy"="Unrestricted"


            works indeed too.

              For some reason the PowerShell cmdlet did not enable local execution globally, just for the local user context. If I tried to start a Powershell script from inside CygWin's bash prompt, for example, which runs under its own user context, it would not run, giving the "is not digitally signed" error. The answer was to go into the Local Group Policy Editor -> Local Computer Policy -> Administrative Templates -> Windows Components -> Windows PowerShell and double-click on 'Turn on Script Execution'. This then let me change it to 'Enabled' and then execution policy of "Allow local scripts and remote signed scripts" and have it work globally regardless of user context.

                The accepted answer is right, but the policy modification is only available for the currently running instance of the Powershell, meaning once the instance of the Powershell is shut down. The policy will be reset. If a user reopens another instance of Powershell, the default policy will be applied which is Restricted



                For me, I need to use the VisualStudio Code console and g++ from cygwin to build things. The console is using Powershell, with the default policy, nothing can be done. One solution is changing the policy everytime the console is fired in VisualStudio Code console, maybe a script of changing the policy.



                I am lazy, so another solution is when I run the Powershell in admin mode, similar to what the accepted answer does. but with an extra parameter which changes values in the Registry table. Once it been done. Other instances of Powershell will use the RemoteSigned policy by default.



                set-executionpolicy remotesigned -Scope CurrentUser

                  The reason that the reg key works, is because it is doing exactly what the PS commands do. The commands write the changes to the reg keys. Commands are much quicker and easier than creating a reg key or digging into the registry.

                    That is just wrong: the keys that were mentioned in other answers change the powershells execution policy, which then enables the powershell script to run.

                    Is there a way to enable execution of a specific powershell script? So perhaps I just want to allow hello.ps1 from the OP, or Microsoft.PowerShell_profile.ps1 on a user's box? (I think that arguably falls under the admittedly broad OP question (ha, which I now see is also yours!). If you feel that's a new question, though, I can ask it.)

                  The Default Execution Policy is set to restricted, you can see it by typing:

                  On my machine that I use to dev scripts, I will use -unrestricted as above. When deploying my scripts however, to an end user machine, I will just call powershell with the -executionpolicy switch:

                  We can get the status of current ExecutionPolicy by the command below:



                  Get-ExecutionPolicy;


                  By default it is Restricted. To allow the execution of PowerShell Scripts we need to set this ExecutionPolicy either as Bypass or Unrestricted.



                  We can set the policy for Current User as Bypass or Unrestricted by using any of the below PowerShell command:



                  Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass -Force;

                  Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted -Force;


                  Unrestricted policy loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the Internet, you are prompted for permission before it runs.



                  Whereas in Bypass policy, nothing is blocked and there are no warnings or prompts during script execution. Bypass ExecutionPolicy is more relaxed than Unrestricted.

                          Depending on the Windows version and configuration, you may have the following warning, even in Unrestricted mode:

                          Run only scripts that you trust. While scripts from the internet can be useful, this

                          The solution is to use the "bypass" policy, enabled with the following command:



                          Set-ExecutionPolicy Bypass


                          From the documentation:

                                  For some reason the PowerShell cmdlet did not enable local execution globally, just for the local user context. If I tried to start a Powershell script from inside CygWin's bash prompt, for example, which runs under its own user context, it would not run, giving the "is not digitally signed" error. The answer was to go into the Local Group Policy Editor -> Local Computer Policy -> Administrative Templates -> Windows Components -> Windows PowerShell and double-click on 'Turn on Script Execution'. This then let me change it to 'Enabled' and then execution policy of "Allow local scripts and remote signed scripts" and have it work globally regardless of user context.

This then let me change it to 'Enabled' and then execution policy of "Allow local scripts and remote signed scripts" and have it work globally regardless of user context.

                                          The accepted answer is right, but the policy modification is only available for the currently running instance of the Powershell, meaning once the instance of the Powershell is shut down. The policy will be reset. If a user reopens another instance of Powershell, the default policy will be applied which is Restricted



                                          For me, I need to use the VisualStudio Code console and g++ from cygwin to build things. The console is using Powershell, with the default policy, nothing can be done. One solution is changing the policy everytime the console is fired in VisualStudio Code console, maybe a script of changing the policy.



                                          I am lazy, so another solution is when I run the Powershell in admin mode, similar to what the accepted answer does. but with an extra parameter which changes values in the Registry table. Once it been done. Other instances of Powershell will use the RemoteSigned policy by default.



                                          set-executionpolicy remotesigned -Scope CurrentUser

                                                  The reason that the reg key works, is because it is doing exactly what the PS commands do. The commands write the changes to the reg keys. Commands are much quicker and easier than creating a reg key or digging into the registry.
