SystemIcons.Shield

Seasoned Windows Forms developers will be familiar with the System.Drawing.SystemIcons class that has a bunch of properties returning standard system icons. For example, if you throw on a form a picturebox and a button with its event handler the following code shows how you can take advantage of SystemIcons:
void button1_Click(System.Object sender, System.EventArgs e)
{
  // use Error
  pictureBox1.Image = Bitmap.FromHicon(SystemIcons.Error.Handle);

  // use Warning
  this.Icon = SystemIcons.Warning;     

  // use Information
  int h = button1.ClientSize.Height / 2;
  Icon ico = new Icon(SystemIcons.Information, h, h);
  Bitmap bitmap1 = Bitmap.FromHicon(ico.Handle);
  button1.Image = bitmap1;
  button1.ImageAlign = ContentAlignment.MiddleLeft;     
}
With Service Pack 1 of .NET Framework v2.0 we get a new member of that class: SystemIcons.Shield. So, if you are on Windows Vista and you are working with User Account Control, you may find it a useful icon to use (for example on a menu).

Below is a screenshot of what the code above looks like side by side, before clicking the button and after. The screenshot at the bottom is after replacing the 3 icons with shield:
