I can without problem call fonts installed in the texmf tree by
names in windows.

It works if one use a symbolic name like \rmfamily:

\documentclass[12pt]{article}
\usepackage[dvipsnames]{xcolor}
\usepackage{fontspec}
\setlength{\parindent}{0pt}
\begin{document}

\defaultfontfeatures[\rmfamily]
%\defaultfontfeatures[texgyreadventor-regular.otf]
 {
  Color=Blue,
  BoldFont={texgyreadventor-bold.otf},
  ItalicFont={texgyreadventor-italic.otf},%
  BoldItalicFont={texgyreadventor-bolditalic.otf}%
 }
\setmainfont{texgyreadventor-regular.otf}


Roman text.\par
\textbf{Bold text}\par
\textit{Italic text.}\par
\textbf{\textit{Bold italic text.}}
\end{document}


I don't have the time currently to really look at it, but imho there
is some confusing between "(single) font" and "family".
