计算机系统自动弹出关机界面

计算机系统自动弹出关机界面可以通过VB关机程序实现。该程序可以在计算机托盘处显示图标，双击图标可以显示主界面，同时还可以在托盘菜单中提供多个关机选项。

以下是一个示例的VB关机程序代码：

Imports System.Windows.Forms

Public Class ShutdownProgram
    Inherits Form

    Private notifyIcon As NotifyIcon
    Private contextMenu As ContextMenu

    Public Sub New()
        ' 创建托盘图标
        notifyIcon = New NotifyIcon()
        notifyIcon.Icon = New Icon("icon.ico")
        notifyIcon.Text = "关机程序"

        ' 创建托盘菜单
        contextMenu = New ContextMenu()
        contextMenu.MenuItems.Add("快速关机", AddressOf QuickShutdown)
        contextMenu.MenuItems.Add("重新启动计算机", AddressOf RestartComputer)
        contextMenu.MenuItems.Add("终止当前进程或程序", AddressOf TerminateProcess)
        contextMenu.MenuItems.Add("用其他用户名关机", AddressOf ShutdownWithOtherUser)
        notifyIcon.ContextMenu = contextMenu

        ' 将托盘图标显示在托盘区域
        notifyIcon.Visible = True
    End Sub

    Private Sub QuickShutdown(sender As Object, e As EventArgs)
        ' 执行快速关机操作
        System.Diagnostics.Process.Start("shutdown", "/s /t 0")
    End Sub

    Private Sub RestartComputer(sender As Object, e As EventArgs)
        ' 执行重新启动计算机操作
        System.Diagnostics.Process.Start("shutdown", "/r /t 0")
    End Sub

    Private Sub TerminateProcess(sender As Object, e As EventArgs)
        ' 执行终止当前进程或程序操作
        ' 这里可以根据需要编写代码来终止指定的进程或程序
    End Sub

    Private Sub ShutdownWithOtherUser(sender As Object, e As EventArgs)
        ' 执行用其他用户名关机操作
        ' 这里可以根据需要编写代码来实现用其他用户名关机的功能
    End Sub

    Protected Overrides Sub Dispose(disposing As Boolean)
        ' 清理托盘图标和菜单
        If disposing AndAlso notifyIcon IsNot Nothing Then
            notifyIcon.Visible = False
            notifyIcon.Dispose()
            contextMenu.Dispose()
        End If
        MyBase.Dispose(disposing)
    End Sub

    Public Shared Sub Main()
        ' 启动关机程序
        Application.Run(New ShutdownProgram())
    End Sub
End Class

请注意，上述代码中的"icon.ico"是一个图标文件，你可以替换为你自己的图标文件。

运行上述代码后，你将看到一个托盘图标，双击图标将显示主界面，同时在托盘菜单中会有多个关机选项可供选择。
