Selecting parts of objects
You can use the Select-Object cmdlet to create new, custom PowerShell objects that contain properties selected from the objects you use to create them.
Type the following command to create a new object that includes only the Name and FreeSpace properties of the Win32_LogicalDisk WMI class:
