Get-ExecutionPolicy CurrentUser

CHANGE YOUR EXECUTION POLICY
 ------------------------------
    To change the Windows PowerShell execution policy on your
    computer, use the Set-ExecutionPolicy cmdlet. 

    The change is effective immediately; you do not need to restart
    Windows PowerShell. 

    If you set the execution policy for the local computer (the default)
    or the current user, the change is saved in the registry and remains
    effective until you change it again.

    If you set the execution policy for the current process, it is
    not saved in the registry. It is retained until the current
    process and any child processes are closed. 

    Note: In Windows Vista and later versions of Windows, to run
          commands that change the execution policy for the local
          computer (the default), start Windows PowerShell with the
          "Run as administrator" option.

    To change your execution policy, type:

        Set-ExecutionPolicy -ExecutionPolicy <PolicyName>

    For example: 

        Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

    To set the execution policy in a particular scope, type:

        Set-ExecutionPolicy -ExecutionPolicy <PolicyName> -Scope <scope>

    For example: 

        Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

    A command to change an execution policy can succeed but
    still not change the effective execution policy.

    For example, a command that sets the execution policy for
    the local computer can succeed but be overridden by the
    execution policy for the current user.
    

示例：

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
