AUCTeX simply runs `call-process' to start the viewer, then I think it
should be Emacs' duty to find the executable if it has been properly
installed (i.e., the installer changed the appropriate registry keys),
but I don't know if this happens on Windows.

The call-process function can run much more than opening a pdf file. 

You can use w32-shell-execute to open a file with the default Windows associations.

 

I'd like to provide a default value of `TeX-view-program-list-builtin'
that works for as many users as possible, hard-coding a path defeats
this goal, for example for you, if you have it C:\Local, and people
using the portable version that I guess can be placed anywhere.

I think there may have been some misunderstanding.

My only point was to say that people should be allowed to reference an absolute path,

not that you should propose one :-)

If it is explicitly about SumatraPDF, assume that it is on the path and use only "SumatraPDF.exe"

As a default value for a pdf viewer, you can rely either on w32-shell-execute or use call-process

with "start %s".
