The OperatingSystem Class provides a method to copy an instance of OperatingSystem, and a method to return a string representation of operating system information.
The OperatingSystem class is not a general purpose class and you cannot derive a more inclusive type from the OperatingSystem class. If you need a type to contain other information about an operating system, create your own type, then include a field of type OperatingSystem and any additional fields, properties, or methods you require.
The Environment Class provides information about, and means to manipulate, the current environment and platform. The Environment Class has a property called OSVersion which returns an object of type OperatingSystem.
Dim _os As OperatingSystem _os = Environment.OSVersion
