Set-ExecutionPolicy Unrestricted

Using the Set-ExecutionPolicy Cmdlet

Changing the Windows PowerShell Script Execution Policy

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:
