Welcome to the forums.
What do you mean with
What did you expect? Did you check the execution policy after you changed it? You can do with
Get-ExecutionPolicy
If you’re not sure how a cmdlet works you should read the help. You should read it completely including the examples to learn how to use it.
If you read the help carefully until the end of it you will see what the usual output of this cmdlet is. 
BTW: Most of the time it is not very helpful to post a picture of code or error messages. Instead you should post the text and format it as code with icon </> in the edit bar.
