C#代码实现隐藏任务栏、开始菜单和禁用任务管理

一：截图，主要是调用系统接口和更改注册表实现功能

二：代码

public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}

#region 隐藏、显示任务栏

[DllImport("user32.dll")]
public static extern IntPtr FindWindow(String className, String captionName);

[DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hwnd, uint nCmdShow);

//隐藏光标
[DllImport("user32.dll", EntryPoint = "ShowCursor")]
public static extern bool ShowCursor(bool bShow);
//ShowCursor(false);
private void btnHideToolBar_Click(object sender, RoutedEventArgs e)
{
// 获得任务栏和开始菜单的句柄
var rwl = FindWindow("Shell_TrayWnd", null);
var rwl2 = FindWindow("Button", null);

if (btnHideToolBar.Content == "隐藏")//当nCmdShow=0---隐藏；nCmdShow=1---显示
{
ShowWindow(rwl2,1 );
ShowWindow(rwl, 1);
ShowCursor(true);
btnHideToolBar.Content = "显示";
}
else
{

ShowWindow(rwl2, 0);
ShowWindow(rwl, 0);
ShowCursor(false);
btnHideToolBar.Content = "隐藏";
}
}
#endregion
//禁用、启用任务管理器
private void btnManageForm_Click(object sender, RoutedEventArgs e)
{

if (btnManageForm.Content == "禁用")//当nCmdShow=0---隐藏；nCmdShow=1---显示
{
//禁用本机的任务管理器
Registry.SetValue("HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", "DisableTaskMgr", 1);
//禁用当前用户任务管理器
Registry.SetValue("HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", "DisableTaskMgr", 1);
btnManageForm.Content = "启用";
}
else
{
//禁用本机的任务管理器
Registry.SetValue("HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", "DisableTaskMgr", 0);
//禁用当前用户任务管理器
Registry.SetValue("HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System", "DisableTaskMgr", 0);
btnManageForm.Content = "禁用";
}
}

}
}
