Uninstallation of MiKTeX on windows by conda

MiKTeX can be installed using conda on windows

% conda install -c conda-forge miktex

This is uninstalled by

% conda uninstall miktex

But if again installing it, it fails. AppData/Roaming/MiKTeX has to be removed manually. Perhaps AppData/Local/MiKTeX, too. Then reinstallation becomes possible.
