FontRegister

FontRegister is both a command-line tool and a csharp native library (pure code) for installing and uninstalling fonts on Windows.

Key Features

• Ability to install/uninstall fonts in bulk.
• Notify Windows OS about new fonts refreshing the font-lists on other apps immediately (photoshop, word and so on).
• Written in pure C# and Pinvoke with a simple code-first API.

Supported Font Types

The following font file extensions are supported:

".ttf"  // TrueType Font
".otf"  // OpenType Font
".fon"  // Windows Font
".ttc"  // TrueType Collection
".fnt"  // Windows Font

Usage

# Note: All font operations require administrator rights

# INSTALLATION EXAMPLES:

# 1. Basic Installation (for current user)
# Installs fonts by copying them to Windows Fonts directory
fontregister install "c:/folder" "c:/font.ttf" "./relativedir/font.otf"
# Note: Folders are searched recursively for font files

# 2. Specify Installation Scope
# For current user (default)

# UNINSTALLATION EXAMPLES:
