intentions to phase out WinHelp as a supported platform. Ted Dworkin (Partner Director of WinHelp Experience) stated, "WinHelp does not meet the code standards established for Vista. These standards include security, reliability, and performance." He went on to say that WinHelp is designed in such a way that, "...we would have to rewrite it from the ground up to meet the Vista code standards. And that approach doesn't make sense given that we have two other Help systems in Vista." The updated licensing agreement prohibits application developers from packaging the WinHelp libraries with their installers. This means that WinHelp manuals for legacy applications are not readable on a new Windows Vista (or higher version) installation. To read them, the end-user must obtain the 32-bit WinHelp viewer from Microsoft's website and manually install it. Starting with Windows 10 Microsoft does not offer WinHelp viewer for this (or higher) version. The last version of Windows on which it was possible to open WinHelp files, using an official downloadable component by Microsoft, is Windows 8.1. The open-source version of winhlp32 from Wine also works on Windows 10. It is included as part of WineVDM. Also on Windows 10 WinHelp works with winhlp32.exe from older version of Windows. Other documentation file formats Although documentation can be maintained entirely in a vendor-specific presentation format such as WinHelp, it is more often the case that documentation must be published in multiple presentation formats at once: Microsoft Compiled HTML Help (CHM), WinHelp, HTML pages, Java Help, PDF, etc. It would be very expensive and error-prone to maintain each format separately. For this reason, authors often maintain documentation in an industry-standard, vendor-neutral authoring format—such as DocBook or FrameMaker—that can be used to generate several different presentation formats (including WinHelp). Various presentation files thus produced (with WinHelp or other tools) contain consistent content because they were generated from the same source.
