WinPopup is a program that enables users running Microsoft Windows 95 or 98 to send text messages, such as "hello world," to one or more users on a network. Later versions of Microsoft Windows, such as Windows 2000 and Windows XP, utilize the net send command to send messages to other Windows users. Below is an example of what the Microsoft WinPopup window looks like in Microsoft Windows 98.
