The Set-ExecutionPolicy cmdlet enables you to determine which Windows PowerShell scripts (if any) will be allowed to run on your computer. Windows PowerShell has four different execution policies:
-
Restricted - No scripts can be run. Windows PowerShell can be used only in interactive mode.
-
AllSigned - Only scripts signed by a trusted publisher can be run.
-
RemoteSigned - Downloaded scripts must be signed by a trusted publisher before they can be run.
-
Unrestricted - No restrictions; all Windows PowerShell scripts can be run.
To assign a particular policy simply call Set-ExecutionPolicy followed by the appropriate policy name. For example, this command sets the execution policy to RemoteSigned:
Set-ExecutionPolicy RemoteSigned
