How to change the default doc for Windows "New"

I have changed the default template in LO Writer, so File/New/Text Doc creates a doc with the correct font.
But if I right-click in a folder and create a new OpenDocument Text doc, it has a different font by default.
How can I make the Windows default be the same as the LO Writer default ?

Which version do you use? It might be installation path/share/template/shellnew/soffice.odt. But I cannot test it, because I do not install, but only unpack the msi file.

When you use the right click context menu New for OpenDocument Text it does not use the default template set for a writer document. There are a set of different templates used for this. They are located at Program Files\LibreOffice (ver)\share\template\shellnew. For a Writer document it is soffice.odt - a file and not a template. You will need to modify this. Some people have reported that spellcheck does not work on documents created using the context menu.
