VB.Net调用WMI可以实现系统管理和系统信息查询等。WMI全称为Windows Management Instrumentation，利用WMI我们可以实现很多系统管理的功能，msdn在.Net Framework类库中对此描述比较简单（因为早期WMI相关专题有所较详尽描述，故类库中未再详细解说与演示）。
开发环境： VB2005 Windows2003
本实例需要在菜单栏中的“项目”-“ 添加引用” -“ System.Management”并在实例代码中导入引用的项目和程序集中定义的命名空间或编程元素 即： Imports System.Management

代码如下：
Private Sub Lobdotcn() Dim Lob_Searcher As New ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_BootConfiguration") For Each Obj_Query As ManagementObject In Lob_Searcher.Get() ListBox1.Items.Add("乐博网LOB.Cn VB.Net爱好者的组织") ListBox1.Items.Add("BootDirectory: " & Obj_Query("BootDirectory")) ListBox1.Items.Add("Caption: " & Obj_Query("Caption")) ListBox1.Items.Add("ConfigurationPath: " & Obj_Query("ConfigurationPath")) ListBox1.Items.Add("Description: " & Obj_Query("Description")) ListBox1.Items.Add("LastDrive: " & Obj_Query("LastDrive")) ListBox1.Items.Add("Name: " & Obj_Query("Name")) ListBox1.Items.Add("ScratchDirectory: " & Obj_Query("ScratchDirectory")) ListBox1.Items.Add("SettingID: " & Obj_Query("SettingID")) ListBox1.Items.Add("TempDirectory: " & Obj_Query("TempDirectory")) Next End Sub
相关属性说明：
BootDirectory Data type: string Access type: Read-only Path to the system files required for booting the system. Example: "C:\Windows" Caption Data type: string Access type: Read-only Qualifiers: MaxLen(64) Short description (one-line string) of the CIM_Setting object. This property is inherited from CIM_Setting. ConfigurationPath Data type: string Access type: Read-only Path to the configuration files. This value may be similar to the value in the BootDirectory property. Description Data type: string Access type: Read-only Description of the CIM_Setting object. This property is inherited from CIM_Setting. LastDrive Data type: string Access type: Read-only Last drive letter to which a physical drive is assigned. Example: "E:" Name Data type: string Access type: Read-only Qualifiers: Key, MaxLen(256) Name of the boot configuration. It is an identifier for the boot configuration. ScratchDirectory Data type: string Access type: Read-only Directory where temporary files can reside during boot time. SettingID Data type: string Access type: Read-only Qualifiers: MaxLen(256) Identifier by which the CIM_Setting object is known. This property is inherited from CIM_Setting. TempDirectory Data type: string Access type: Read-only Directory where temporary files are stored. Example: "C:\TEMP"
