Windows Chat (not to be confused with Microsoft Comic Chat) is a simple LAN-based text chatting program included in Windows for Workgroups and, later, the Windows NT-line of operating systems, including Windows NT 3.x, NT 4.0, Windows 2000, Windows XP and Windows Server 2003 and also Windows 95. In later Windows versions, the Network DDE service may need to be enabled to receive calls.{{cite web |url=http://support.microsoft.com/kb/308232 |title=Using Windows Chat in Windows XP |website=Microsoft Support |archive-url=https://web.archive.org/web/20140608214400/http://support.microsoft.com/kb/308232 |archive-date=2014-06-08 |access-date=2017-07-13}} It utilizes the NetBIOS session service and NetDDE.

Windows Chat utilizes a split screen user interface similar to UNIX talk. Windows Chat is real time text, with typing being transmitted immediately.

However the application can still be used through programs such as virtual machines if earlier versions of Windows are installed on them.
