Change system font to TCVN3

Change system font to TCVN3 is a lightweight Windows utility that switches your system UI font to a TCVN3‑compatible typeface, ensuring legacy Vietnamese TCVN 3 (ABC) documents and applications display correctly on modern PCs. It provides a guided, reversible process so you can enable compatibility when needed and restore your original look at any time.

Key features:

• One‑click switch to a TCVN3‑compatible system font (e.g., VnTime/VnArial)
• Automatic backup and easy restore of your original font settings
• Detects missing TCVN3 fonts and helps you install them
• Option to apply changes system‑wide or only to selected UI areas
• Clear prompts and restart guidance

Ideal for:

• Users working with older Vietnamese documents and software
• Offices, schools, archives, and libraries maintaining legacy content

Notes:

• Administrator privileges and a restart may be required to fully apply changes.
• Modifying the system font can affect layout and readability in some apps; use the restore option if needed.
• If you primarily use Unicode content, no change is necessary—enable TCVN3 only for legacy compatibility.
