How to enable execution of PowerShell scripts?

Question

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

File C:\Common\Scripts\hello.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 <<<<
+ CategoryInfo : NotSpecified: (:) [], PSSecurityException
+ FullyQualifiedErrorId : RuntimeException

Answer 1

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

Answer 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.
