How to Change Telegram’s Font on Windows Desktop via Regedit

Telegram Desktop doesn’t offer built-in settings to change its font. However, it follows the Windows system font by default. Do you want to give Telegram a fresh look with a different font style? You can achieve this by tweaking the Windows registry. This guide will walk you through the process using the Registry Editor (Regedit) on Windows 11. If you don’t have the Telegram Desktop App, can you download it here?

⚠️ Important Note: Modifying the registry can affect your system. Please follow the steps carefully and back up your registry beforehand. For the moment, you can try this solution first to change the Telegram font on the Windows Desktop App.

🔧 Steps to Change the System Font (and Telegram’s Font) via Regedit

1. Choose the Font You Want

Pick a font that is already installed on your system (e.g., Segoe UI, Comic Sans MS, Arial, Verdana, Tahoma, etc.). You’ll need the exact name of the font. This tip, I show you with font Tahoma, so you can use it with another font that you like.

2. Open Registry Editor

1. Press Win + R to open the Run dialog.
2. Type regedit and hit Enter.
3. If prompted by UAC (User Account Control), click Yes to allow.

After clicking on OK => Yes

3. Navigate to the Font Substitution Key

Go to the following registry path:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts

👉 Here you can confirm the names of fonts installed on your system, which will help with the next steps.

4. Create a New Registry Script

Instead of editing registry keys manually (which can be tedious), it’s easier to create a .reg file:

1. Open Notepad.
2. Paste the following template:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
"MS Shell Dlg 2"="YourFontName" (Tahoma)

👉 Replace "YourFontName" with the exact name of the font you want to use, e.g., "Hahoma".

Then, clicking on OK,

3. You can also create a new file with a note file. Enter your preferred font and save the file with a .reg extension, like: ChangeFont.reg

5. Apply the Registry File

1. Double-click the .reg file you just saved.
2. Accept the warning and confirm that you want to make changes.

6. Restart Your Computer

To apply the changes, restart your PC. Once Windows boots up, system fonts (including those in Telegram Desktop) should reflect your new font choice.

✅ Wrapping Up

That’s it! You’ve now that by modifying the Windows system font through the Registry Editor. Keep in mind this change will affect other apps that rely on the system font too.

If you ever want to revert back to the default font, you can either:

• Delete the "Segoe UI" override in FontSubstitutes, or
• Restore your registry from the backup you (hopefully) created.
