Execution Policy Will Not Change?

Hi there,

Kind of a newbie to Powershell.

I am trying to run a powershell script, unusually No matter what I do when I run Set-ExecutionPolicy Unrestricted it takes me to the part where I need to enter Y, which when I normally do it at work, it then works, on my personal machine however it does not change when I check. The Powershell window just opens for a second and then closes.

Any advice? I am just practicing powershell at home.
