I use WinShell with PDFLatex on Windows 7. I managed to install Pygmentize and compile the minimum example without errors:
\documentclass{article}
\usepackage{minted}
\begin{document}
inline: \mint{python}|import this|
\begin{minted}{c}
int main() {
printf("hello, world");
return 0;
}
\end{minted}
\end{document}
However, the output is strange. It shows tex code in the document, which is nicely formatted as if it was Python code:

Any idea how this could happen? Please comment, if more information is needed.
Update
I compile via WinShell, my PDFLatex command line looks like this:
"C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\pdflatex.exe" -shell-escape -aux-directory=./.aux -interaction=nonstopmode -synctex=-1 "%s.tex"
mintedis not very well behaving on Windows. – egreg Mar 13 '13 at 16:31
