How do you successfully change execution policy and enable execution of PowerShell scripts

I have a problem regarding changing the Execution Policy in my Windows Server 2008+ OS. It is the first time I try to run a script for which I need resource full access and I try the following after starting Powershell in elevated mode:

Set-ExecutionPolicy Unrestricted

But I get this:

Set-ExecutionPolicy : Windows PowerShell updated your execution policy
successfully, but the setting is overridden by a policy defined at a more
specific scope.  Due to the override, your shell will retain its current
effective execution policy of RemoteSigned. Type "Get-ExecutionPolicy -List"
to view your execution policy settings. For more information please see
"Get-Help Set-ExecutionPolicy".

The problem is that Windows does not allow all scripts to be executed in Unrestricted mode. Actually, no matter the execution policy for your user (even if administrator), the Local Group Policy will take priority.

And by default the local group script execution policy is such for which scripts are not allowed to be executed. We need to change it!

Changing the Local Group Execution Policy

We do this via the Local Group Policy Editor which you can reach by searching in the Windows Search bar for "group policy". Or do this:

  1. Open the Management Console by hitting Win + r and typing command mmc.
  2. Go to File -> Add Remove Snap In....
  3. In the left pane find Group Policy Object Editor and add it.
  4. Close the form.

Then on the left pane the group editor can be expanded. Expand it and navigate to Computer Configuration -> Administrative Templates -> Windows Components.

Then to Windows PowerShell.

So select Turn on Script Execution. Change configuration to Enabled and specify Allow all scripts in Execution Policy.

Confirm by hitting Ok and close the Management Console.

Comments
  • What do you do if Windows Power Shell is not in the list?
  • I found the answer, you need to download version 4 on Windows Power Shell from here: microsoft.com/en-us/download/confirmation.aspx?id=40855
  • Additionally, I had to install the hotfix in the answer below by @diganta-kumar
  • Excellent indepth info. however mine issue fixed after uninstalling and re-installing the Nuget package extension for VS 2013 from extension and updates
  • I had to run also Set-ExecutionPolicy "Unrestricted" -Scope CurrentUser -Confirm:$false
  • Beware that this answer is unrelated to the problem described in the question. It resolves a problem with a Visual Studio extension.
  • I don't think this gets around the group policy. At least not for me. In my case the key did not exist under HKLM though it did under HKCU. However your script still did not avoid the security.
  • This is terrible advice. Not only does it at best temporarily mitigate the symptom (group policies are re-applied periodically, by default every 90-120 minutes), it also usually means you're violating corporate policies, which may result in legal action.
  • Worked for me. Thanks.
  • Good solution. Visual Studio 2015 running the scripts natively sometimes works and sometimes hangs. This works every time. Thanks Marc
