TEXMFHOME on Windows

[Peter Flynn]

A user has asked me why a private class file isn't being found. They are 
running TL under Windows (I have asked them which versions) and has put 
the file in C:/Users/username/texmf which is what TEXMFHOME gets 
expanded to.

My understanding is that TEXMFHOME does not need any ls-R database, but 
my understanding of Windows is poor; and I thought the canonical 
location was Computer\System\Users\username\texmf (avoiding the need for 
C:, D:, etc)

I have asked them to move the file to 
C:/Users/username/texmf/tex/latex/username/algoslides.cls and report back.

If C:/Users/username/texmf is created at install time, presumably no 
further action is needed by a user, but do they need to use the TDS 
structure within that directory?
