Microsoft launched Windows 3.0 in 1990, becoming a popular operating system predominantly due to its introduction of a new graphical user interface (GUI) that displayed applications as clickable icons. It significantly enhanced the experience and made multitasking feel seamless compared to earlier versions.
The tech giant also shipped Microsoft 'WinHelp' as part of the OS, which was essentially a system designed for browsing online help files in Windows applications.
WinHelp was an important tool designed to make the entire UX in Windows 3.0 through to Windows XP better with each release. However, Microsoft pulled the plug on the legacy help system when it shipped Windows Vista to discourage software developers from using the tool and transition to modern formats.
Recently, veteran Microsoft engineer Raymond Chen published a fascinating blog post explaining why Windows 3.0’s WinHelp was called an online help system when it actually ran offline in his ongoing The Old New Thing series.
According to Chen, Windows 3.0 predated the Internet, yet WinHelp's help files were still accessible even though the computer wasn't connected to any network. This premise seemingly challenged the conventional meaning of being "online".
The term “online” originally meant “immediately available on a computer”. For example, if you are working on a system with hierarchical storage, the “online” files are the ones that are accessible right now, and the “offline” files are the ones that have been archived to tape and will take some time to retrieve and make online.

However, Chen clears the air by indicating that WinHelp was simply regarded as an online help system since the help files were readily available on the device, alleviating the need to seek aid through manuals.
Perhaps more interestingly, the engineer indicated that a computer that was accessible through a network connection was called "up" instead of "online". According to Chen:
"Officially, “up” referred to whether the computer was running at all, but since these types of computers (mainframes or timesharing systems) had as their sole purpose to be connected to by other computers, being “up” was useless if they weren’t also open to connections."
It might take a while to make sense of it all in the context of modern computing, but the main point is that WinHelp was called an "online" help system because the help files were readily available. On the other hand, available offline refers to your computer being available for connection requests from other devices — it's complicated!
Modern Windows operating systems have evolved from the WinHelp legacy online help tool, migrating help files to websites. As such, users can't access these files when they are not connected to a network or are simply offline.
