Can't run script even after running "Set-ExecutionPolicy RemoteSigned"

[trparky]

This is my current setup...

Get-ExecutionPolicy -List

        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy       Undefined
   UserPolicy       Undefined
      Process       Undefined
  CurrentUser    RemoteSigned
 LocalMachine    RemoteSigned

I executed Set-ExecutionPolicy RemoteSigned as per the suggestion yet nothing changes in the Get-ExecutionPolicy -List output. I still receive the following error...
.\UWScript.ps1: File C:\Users\user\Downloads\UnattendedWinstall-2.0.0\UWScript.ps1 cannot be loaded. The file C:\Users\trpar\Downloads\UnattendedWinstall-2.0.0\UWScript.ps1 is not digitally signed. You cannot run this script on the current system.

@trparky Run Set-ExecutionPolicy Unrestricted in PowerShell and then try run the UWScript.ps1 file again.
You can also right click the file and select "Run with PowerShell."
