Windows doesn't let you delete a shared library that's loaded by a process, but
it does let you rename it. So I think the solution would be to rename the .eln
file to something like .eln.old, and then let the GC driven unload machinery to
delete that old file.
Btw, what happens if more than one Emacs session have the same .eln file
loaded, and one of them wants to recompile it?
