## What it is
No!! MeiryoUI is a small Windows utility that restores the ability to change system UI fonts, a feature removed since Windows 8.1. It is a native C++ GUI tool that modifies registry font settings on Windows 8/10/11.

## Use cases
- change the Windows system UI font on Windows 10 or 11
- restore font customization removed since Windows 8.1
- replace the default Meiryo UI font with another typeface
- customize fonts used by Win32 and WinForms applications
- set different fonts for window titlebars, menus, and message boxes

## When to choose
- you want to change system fonts on Windows 8/10/11 without editing the registry manually
- you prefer a lightweight, portable, open-source tool with a GUI
- you use Win32/WinForms apps that respect system font settings

## When to avoid
- you want to change fonts in UWP apps, the taskbar, or apps that ignore system font settings
- you need to change the titlebar font on Windows 11
- you are uncomfortable with tools that modify the registry and may trigger antivirus false positives
