Step 3:
After you complete the above step you should be on this line in your Power Shell console (The computer is running Windows 8.1 Profesisonal and the version of Power Shell is 4.0).

Microsoft SQL Server PowerShell
Version 11.0.2100.60
Microsoft Corp. All rights reserved.

PS SQLSERVER:\>

Now declare an instance of SQL Server using the following:

PS SQLSERVER:\> $server = new-Object Microsoft.SqlServer.Management.Smo.Server('Hodentek8\RegencyPark')

Now declare a user UserX using New-Object.. syntax.

PS SQLSERVER:\> $SqlUser = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Login ('Hodentek8\RegencyPark','Hodentek8\UserX')

Here Hodentek8(host) is the name of the computer; RegencyPark is the name of the instance and UserX is the name of the user.

Choose Windows Authentication using the following command and create the login using the following:

PS SQLSERVER:\>SqlUser.LoginType='WindowsUser'

At this point you should have the computer user called UserX for your computer otherwise you will get this error.
-------------
PS : A positional parameter cannot be found that accepts argument '$null'.
At line:1 char:3
+ PS <<<<  SQLSERVER:\> $SqlUser.LoginType='WindowsUser'
    + CategoryInfo          : InvalidArgument: (:) [Get-Process], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.GetProcessCommand

------------------------
Now create this login by this:

PS SQLSERVER:\>$SqlUser.create()

This completes the steps to create a New User Login which you can verify in SQL Server Management Studio as shown here:
