Using WMI in .NET to get system information.

From my quick reading of using WMI from .NET, it looks like everything you use SQL sort of syntax on a set of "objects". The objects (Win32 classes) are here. For example, look at Operating System, File System, Win32_LogicalDisk.

select FreeSpace, Size, Name from Win32_LogicalDisk where DriveType=3"

Also Operating System, Operating System Settings, Win32_OperatingSystem

Unfortunately, these WMI related queries only work on Windows ME and higher by default, unless you install the WMI package separately on Win9x machines.
