I don't want to close the other program, I just want to remove or hide another's program systray icon from my program. For example, if you configure Winamp to stay on the systray, I'd like to remove that icon but keeping Winamp running.

You have to know some things about the specified icon in the tray.Each program that puts it's icon in the tray passes a WM_COPYDATA message to the taskbar.The lParam (I think ) is a pointer to a TNotifyIconData that helds information about the icon in the tray.If you manage to subclass the taskbar and intercept the message you will have this structure and with Shell_NotifyIcon(NIM_DELETE,@...) we will be able to hide the icon

Sorry , I was wrong. The lParam is a Pointer to a PCopyDataStruct.You can extract TNotifyIconData from PCopyDataStruct lpData member (PNotifyIconData(Integer(PByte(copyData.lpData))+8)) where copyData is of type
PCopyDataStruct

You can do that by using "madKernel", which is free for non-commercial purpose (only). E.g. this:

uses madKernel;

begin
  Process('msimn.exe').TrayIcons.Delete;  // hide Outlook's tray icons
end;
