When I select a theme and make changes to the font name and font size, they always default back to original settings whenever I reopen notepad++. Is there a way of making font name and size changes to any theme in notepad++ permanent?
Run notepad as an administrator; make the desired style changes, save and close notepad++. When you open it again, changes should be visible.
If you do not have administrator rights, changing the entire theme to another theme (e.g. the Twilight theme) is saved permanently even without administrator rights.
