Robert,

I am a Windows/MS-DOS user, not a Windows programmer, so I hope that someone
more knowledgable will also respond.

Windows 3.1/Win 95/Win NT have a temp directory.  There should be an
environmental variable named "temp" which points to it.  Many people use
c:\temp, on my machine it's c:\windows\temp.

Programs such as Word and Excel maintain an .ini file in the c:\windows
directory which record user preferences.  Matlab for Windows keeps
initialization commands in a file matlabrc.m in it's home directory, as well
as an .ini file in the windows directory.  Matlab also looks in the current
working directory to see if there is a file "startup.m"; if so it is
executed after the matlabrc.m.  Every icon or shortcut in Windows is
associated with a working directory or startup directory.

I haven't.  I've heard that it's difficult to automate the creation of
Windows native help.

Am very much looking forward to the Windows version.

All the best
