How to upgrade CodeIgniter from version 4.1.3 to 4.1.4

That might explain why its not updating framework using composer; also it implies you didn't set up codeigniter in xampp with composer either ?

have you got a "tree" command with windows to show directory structure ? I'm guessing you have a system directory ,at the same level as the app directory?

if i was on linux in your position , i think (maybe) get https://github.com/codeigniter4/CodeIgni...tag/v4.1.3
replace system directory , then create patches from my codebase of existing files in app, public , writable with the new equivalent files from 4.1.3 download, in the directories app, public, writable so as to retain your old code, but have it in updated file , if that makes sense

i.e basically a manual upgrade
