PowerShell says "execution of scripts is disabled on this system."

I am trying to run a cmd file that calls a PowerShell script from cmd.exe, but I am getting this error:

Management_Install.ps1 cannot be loaded because the execution of scripts is disabled on this system.

I ran this command:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

When I run Get-ExecutionPolicy from PowerShell, it returns Unrestricted.

Get-ExecutionPolicy

Output:

Unrestricted

cd "C:\Projects\Microsoft.Practices.ESB\Source\Samples\Management Portal\Install\Scripts" powershell .\Management_Install.ps1 1

WARNING: Running x86 PowerShell...

File C:\Projects\Microsoft.Practices.ESB\Source\Samples\Management Portal\Install\Scripts\Management_Install.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details.

The system is Windows Server 2008 R2.

What am I doing wrong?

Answer*

If you're using [Windows Server 2008][1] R2 then there is an _x64_ and _x86_ version of PowerShell both of which have to have their execution policies set. Did you set the execution policy on both hosts?

As an _Administrator_, you can set the execution policy by typing this into your PowerShell window:

```lang-None
Set-ExecutionPolicy RemoteSigned
```

For more information, see *[Using the Set-ExecutionPolicy Cmdlet][2]*.

When you are done, you can set the policy back to its default value with:

```lang-None
Set-ExecutionPolicy Restricted
```

You may see an error:

```lang-None
Access to the registry key
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell1円\ShellIds\Microsoft.PowerShell' is denied. 
To change the execution policy for the default (LocalMachine) scope, 
 start Windows PowerShell with the "Run as administrator" option. 
To change the execution policy for the current user, 
 run "Set-ExecutionPolicy -Scope CurrentUser".
```

So you may need to run the command like this (as seen in comments):

```lang-None
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
```

Set-ExecutionPolicy Restricted seems to be the way to undo it if you want to put the permissions back to as they were: technet.microsoft.com/en-us/library/ee176961.aspx. The temporary bypass method by @Jack Edmonds looks safer to me: powershell -ExecutionPolicy ByPass -File script.ps1

Set-ExecutionPolicy RemoteSigned cannot be the first line in your script. If it is, highlight it and run selected only INITIALLY before running the rest of your script.

I came across a similar question on SF site, "Powershell execution policy within SQL Server" asked Oct 10 '14. The answers there included Get-ExecutionPolicy -List which helped me to see the different scopes. The cmd Get-ExecutionPolicy does not show all the scopes. Import-Module SQLPS is now working with policies changed as follows: {Undefined- Process,MachinePolicy,UserPolicy,}; {RemoteSigned- CurrentUser, LocalMachine}.

If I do this, does the change last for only the duration of the current PowerShell? Or is it bigger than that?

@SharpC, it is Undefined that reverts the policy in a given scope to its default; e.g., Set-ExecutionPolicy -Scope CurrentUser Undefined -Force. While on workstation editions of Windows using Restricted has the same effect, note that - at least nowadays - server editions default to RemoteSigned.
