msg.exe: Windows Messaging Utility

msg.exe is a command-line utility in Windows operating systems that allows administrators and users to send messages to other users on the same network or to a remote computer. It's the successor to the older net send command (which was removed in Windows XP SP2 and subsequent versions). msg.exe uses the Terminal Services session to deliver messages.

Origin and Purpose

msg.exe was introduced as part of the Terminal Services (now Remote Desktop Services) infrastructure. Its primary purpose is to facilitate communication between users connected to the same Terminal Server or between an administrator and users on a remote computer. It's a quick and simple way to send short, text-based messages without requiring email or instant messaging applications.

Functionality

msg.exe sends messages that appear as pop-up windows on the recipient's screen. The message remains on the screen until the user actively dismisses it (clicks "OK"). It's not intended for long-form communication or file transfer; it's primarily designed for short notifications and alerts.
