Msguide ((free)) -

Before the internet became a pocket-sized library, software documentation had a different rhythm. You installed a program, and if you got stuck, you didn’t “Google it”—you pressed F1 . Behind that key often lay a system called msguide.exe . While largely obsolete today, understanding MSGuide offers a fascinating glimpse into the design philosophy of early Windows help systems. What Was MSGuide? MSGuide (Microsoft Guide) was a help engine and file format used primarily in Windows 3.1 and Windows 95 for interactive tutorials and product tours. Unlike standard .HLP files (which used the WinHelp engine), MSGuide-powered content was designed for step-by-step wizards , product showcases , and guided walkthroughs —often with a distinctive "next/back" button interface.

For the average user, msguide is a footnote. But for software historians and retro-computing hobbyists, it represents a moment when Microsoft realized that —not just a manual. And in that sense, every modern help system still walks in MSGuide’s footsteps. Have an old CD-ROM with a TOUR folder? You might just find a working .GUIDE file waiting to be explored.
