HyperTerminal
The terminal program bundled with Windows from 95 to XP — for many people the first and only way onto a BBS.
HyperTerminal was written by Hilgraeve of Michigan, and Microsoft licensed a cut-down version for Windows 95 to replace the bare-bones Terminal of Windows 3.x. It could dial out through a modem, talk to serial ports, transfer files with XMODEM and ZMODEM, and render basic ANSI graphics.
BBS users with opinions rarely picked it first; Telix, Procomm Plus and Qmodem were faster and sharper. But it was already installed, and that counted for a lot. Microsoft dropped it in Windows Vista, after which it lived on mainly in the memories of network engineers plugged into a router's console port. Hilgraeve still sells a standalone edition.
