To allow running a specific script (recommended for security): This enables you to run a specific script, but does not open rules for every script. It's a good compromise between security and function. If a computer won't allow a script to run., then get-excecutionPolicy and ensure it is remote-signed. if it is not then Set-ExecutionPolicy -ExecutionPolicy RemoteSigned . run your script then then set it back to original once your work is done. Or unblock-file the specific script you want to run.
