WinHelp
proprietary format for online help files that can be displayed by the Microsoft Help browser
Microsoft WinHelp is a proprietary format for online help files that can be displayed by the Microsoft Help browser winhelp.exe or winhlp32.exe. The file format is based on Rich Text Format (RTF). It remained a popular Help platform from Windows 3.0 through Windows XP. WinHelp was removed in Windows Vista and Microsoft discouraged software developers from using the obsolete format and encouraged use of newer help formats. Support for WinHelp files would eventually be removed entirely in Windows 10.
History
1990 – WinHelp 1.0 shipped with Windows 3.0.
1995 – WinHelp 4.0 shipped with Windows 95 / Windows NT.
2006 – Microsoft announced its intentions to phase out WinHelp as a supported platform. WinHelp is not part of Windows Vista out of the box. WinHelp files come in 16 bit and 32 bit types. Vista treats these files types differently. When starting an application that uses the 32 bit .hlp format, Windows warns that the format is no longer supported.
Begin with the source’s own compact description: “WinHelp” is proprietary format for online help files that can be displayed by the Microsoft Help browser. The dossier treats that line as a proposition to test through WinHelp, proprietary and format, not as a finished interpretation.
Why this record matters
The phrase “proprietary format for online help files that can be displayed by the Microsoft Help browser” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
