Introduction 

WMI (Windows Management Instrumentation) provides programmers with information about the Operating System. This project includes the known WMI list.

Using the code

The Wmis.csv file contains the WMI paths like this:

• Keyboards and Pointing Devices;Win32_Keyboard
• Keyboards and Pointing Devices;Win32_PointingDevice
• Mapped Drives and File Shares;Win32_ConnectionShare
• Mapped Drives and File Shares;Win32_LogicalShareAccess

    Const FileName As String = "WMIs.csv"

    Using fs As New FileStream(FileName, FileMode.Open)
        Using sr As New StreamReader(fs)
            While (sr.Peek > -1)
                Dim Line As String = sr.ReadLine
                Dim params() As String = Line.Split(";")
                Dim RootNode As TreeNode

                If Not twWMIs.Nodes.ContainsKey(params(0)) Then
                    Dim newNode As New TreeNode(params(0))
                    newNode.Name = params(0)

                    twWMIs.Nodes.Add(newNode)

                Else
                    RootNode = twWMIs.Nodes.Find(params(0), False)(0)
                End If

Points of Interest

You can use WMI to learn information about your computer, Operating System, etc... For example, network card mac address, installation date of OS, processor ID, etc... Please be sure to use the UAC settings. You may need the admin rights while reading some WMI information...
