'The SystemVariable property indicates whether the variable is a system variable. A system variable is set by the operating system, and is independent from user environment settings. Values: TRUE or FALSE. A value of TRUE indicates the variable is a system variable.'
'The UserName property indicates the owner of the environment setting. It is set to "" for settings that are specific to the Win32 system (as opposed to a specific user) and "" for default user settings. Example: Jsmith.'
'The VariableValue property contains the placeholder variable of a Win32 environment variable. Information like the file system directory can change from machine to machine. The operating system substitutes placeholders for these. Example: %SystemRoot%.'
'The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.'
'The Name property contains a character string specifying the name of a Win32 environment variable. By specifying the name of a variable that does not yet exist, an application can create a new environment variable. Example: Path.'
'The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.'
