By default the PowerShell execution policy is set to restricted, which does not allow the PowerShell Scripts to be run. There are 4 possible execution policies in PowerShell:
- Restricted – the default setting, doesn’t allow any scripts to run.
- AllSigned – only runs scripts which are signed by a trusted digital certificate
- RemoteSigned – runs local scripts without requiring them to be trusted. Scripts downloaded from the Internet must be trusted before they can run.
- Unrestricted – allows all scripts to run, even untrusted ones.
Use the Set-ExecutionPolicy command to “unlock” you work environment. For example if you are using a lab or learning environment you can issue the following command :
IMPORTANT: This setting should not be used in a production environment because it could potentially allow scripts downloaded from internet or planted by viruses to be executed. For a production use AllSigned or eventually Remote Signed policies
