Description
Returns the WshEnvironment object.
Syntax
object.Environment ([strType])
Parameters
Part Description
object WshShell object.
strType Optional. Specifies where the environment variable resides.
Remarks
If strType is supplied, it specifies where the environment variable resides, with a possible value of "System," "User," "Volatile," or "Process." If strType is not supplied, this method retrieves the system environment variables in Microsoft Windows 2000 or the process environment variables in Windows 95/98. For Windows 95/98, only "Process" is supported in the strType parameter.

The following table lists some of the variables that are provided with the Windows operating system. Scripts also can get environment variables that have been set by other applications. None of these variables are available from the "Volatile" type.
