What is Microsoft HTML Help?

Microsoft HTML Help is an online Help standard based on the Hypertext Markup Language (HTML) format. Designed for Windows 98 and Windows 2000, Microsoft intends HTML Help to eventually replace the WinHelp format. (However, Microsoft has committed to including the existing WinHelp engine in Windows 98 and Windows 2000 for backward compatibility.)

The Microsoft HTML Help format that was introduced in August 1997 can be utilized on existing 32-bit Windows platforms and is Microsoft's Help standard for Windows 2000 and future Microsoft applications.
