This utility class provides a large number of static properties that can give you information about the current system settings, such as the HorizontalScrollBarHeight and whether this is a DebugOS.

Note that some of these properties, such as ComputerName and UserName, are retrieved from corresponding environment variables and are therefore susceptible to spoofing, and should not be considered to be secure.
