Windows Registry Editor Version 5.00

"Segoe UI (TrueType)"=""

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionFontSubstitutes]

Replace NEW_FONT_NAME with the name of the font you want to use.

This code will make the necessary registry changes to replace the default system font with the one you specified.

Step 3: Save the File

Save the file with a .reg extension. For example, name it "ChangeFont.reg".

Make sure to select "All Files" in the "Save as type" dropdown to save it correctly as a .reg file.

Step 4: Run the File

Double-click on the .reg file you just saved and confirm any prompts to merge it into the registry.

This action will apply the changes to your system settings, setting your new font as the default.

Step 5: Restart Your Computer

Restart your computer to apply the new font settings.

A restart is necessary for the changes to take effect throughout the system.

After completing these steps, your Windows 11 system font will change to the new font you specified.
