No!! MeiryoUI

No!! MeiryoUI ("Meiryo UI mo daikkirai!!" in Japanese) brings back the capability to customize the user interface font on Windows, a feature that was removed since Windows 8.

No!! MeiryoUI has some limitations on Windows 11 22H2 and later.

If you have some ideas check discussions for support.

Requirements

• Windows 8 or newer.
• While No!! MeiryoUI should work on Windows Vista, it is not actively tested for compatibility.

Installation

[!IMPORTANT] No!! MeiryoUI makes changes to registry. It is recommended to backup your registry before applying any changes.

reg save "HKCU\Control Panel" .\reset_font.reg /y

To restore it later, run the following command with administrator privilege.

reg restore "HKCU\Control Panel" .\reset_font.reg

The archive also contains utils\SAVEreg.bat and utils\RESTOREreg.bat which do the same.

• Download zip archive from GitHub Releases.
• Extract the archive and run "noMeiryoUI.exe".

Features

• Change the font of each user interface element separately, or all at once: title bar, icon, palette title, hint (status bar), message box and menu.
• Preset menu to reset fonts to the defaults of Windows 8/8.1, 10 and 11.
• Save / load font settings to / from a file.
• Interface and help are available in English, Japanese, Korean, Brazilian Portuguese, Simplified Chinese and Traditional Chinese.

Known Limitations

• No!! MeiryoUI does not work with:

  • Windows taskbar.
  • Preinstalled UWP Apps (e.g. Settings, Paint, etc.).
  • Applications that ignore the system font settings.

• No!! MeiryoUI cannot modify the titlebar font on Windows 11.

• No!! MeiryoUI might be detected as Trojan/virus software by some antivirus software because No!! MeiryoUI changes system font settings.

Documentations

You can find detailed documentation on the wiki. The help file (.chm) is also included in the release archive; its sources are in the help folder.

Building

The source code is in the program folder.

1. Install Visual Studio with the C++ desktop development workload.

2. Open the solution file for your Visual Studio version.

   Solution	Visual Studio
   program\noMeiryoUI.sln	2022 or later (v143)
   program\noMeiryoUI_2012.sln	2012 (v110)
   program\noMeiryoUI_2008.sln	2008

3. Build the Release configuration. The executable is generated in program\bin\Release (2022 or later) or program\bin_2012\Release (2012).

Release packages (portable zip, installer and language packs) are made with the scripts in the packaging folder. The portable and installer versions use the Visual Studio 2012 build, because Microsoft Defender treats executables built by later versions as a virus.

Translations

Translations of the interface (lang) and the help (help) are welcome. See the Wiki for how to translate, and CONTRIBUTING.md for how to submit them.
