Win32.chm: Microsoft's Old API Help File Reborn (laurencejackson.com)

My son and I have been using the Win32 API and Lua 5.2 to make fun things, such as a simple window manager and a simple Love2d clone. This file is extremely helpful especially considering we don't have internet at home, and MS Visual Studio Community doesn't seem to come with offline API documentation.

Neat. I wanted to play around with old OS interfaces a bit this year and this might just be what I need for the NT/ReactOS part.
