- RemoteSigned. Requires that all scripts and configuration files downloaded from the Internet be signed by a trusted publisher.
- Unrestricted. Loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the Internet, you are prompted for permission before it runs.
- Bypass. Nothing is blocked and there are no warnings or prompts.
- Undefined. Removes the currently assigned execution policy from the current scope. This parameter will not remove an execution policy that is set in a Group Policy scope.
