A while back [I blawgd about how to get the MSDN library for offline use](https://blag.nullteilerfrei.de/2017/12/21/get-the-msdn-library-for-offline-use/). However, the Help Viewer has its problems. I won't list all of its problems, but it was certainly a bad candidate to integrate Win32 API documentation support to Ghidra. There is [a pretty neat project by Laurence Jackson](http://laurencejackson.com/win32/), but I think I just found something a little better even: Microsoft provides [a download of the MSDN Library for Visual Studio 2008 SP1, stand-alone, offline, as an ISO](https://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=20955) - smell this, Help Viewer: So this is nice, but the main point of this exercise was to integrate this into Ghidra. If that's something you care about, read on.
