Delete nextcloud client completely windows 10

Expected behaviour:
When uninstalling the windows client, all files and data from nextcloud ist deleted

Actual behaviour:
When uninstalling and installing again, all links set in the app (so all sync parameters) are again there. So nextcloud must store some userdata somewhere.

How can I completely delete all the data from the windows client?

Most software store user settings in %appdata% and should never be deleted if you uninstall it. This is the expected behaviour. Open this folder and delete the nextcloud folder inside it.

I think even in the current version the experience is still the same. I feel it would be good if as part of deinstallation process it is asked whether accounts details should be deleted.
