The automatic installer can not detect the need for cm-super. It can
detect missing files, but there is no tfm missing. Microtype can
imho do no much either. The error message is from the engine.

No. It e.g. affects also copy and paste. Try it out

\documentclass{article}
%\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\begin{document}
öäü
\end{document}

And OT1-encoding has some other curious side-effect:

\documentclass{article}
%\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\begin{document}
<a \texttt{£}
\end{document}

Imho T1 should be the default encoding, type1 fonts the default font
format. So either latex uses lmodern by default of cm-super should
be installed. Also I don't think that it matters much today -- some
years ago this was different - I always imported cm-super from older
miktex versions to save download time.
