What Replaces Winhelp ?

Iain,

More or less, yes, although the WinHelp executable is still available from the Microsoft Download Center for those users who don't have it. That's just Vista and Windows Server 2008 users at the moment, I believe.

If you're happy to use a third-party solution like KeyHelp then, yes, much improved. See:

This is true for the Assistance Platform (AP) Help used in Vista. At the moment, we don't know whether a public version of this will ever be made available. I'm not even sure that there's anyone at Microsoft who is actively working on this anymore.

Microsoft Help 2.0 is still around for those who want to integrate their help content into the Visual Studio .NET help system.

There's a little more information on all of this here:

For the time being, I believe the recommendation is broadly: use HTML Help (.chm) for locally installed help; Help 2.0 for .NET help integration; and browser-based help for anything that the first two formats don't suit.
