Creating a REG file to change the default system font on Windows is an alternative method that allows you to quickly apply font changes without navigating through the settings. Here’s a step-by-step guide on how to create a REG file to change the default system font:

• Open Settings, and select Personalization > Fonts.
• Scroll through the list to find the font you want. In our example, we recorded Comic Sans MS.

• Open a text editor such as Notepad.
• Copy and paste the following content into the text editor:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"=""
"Segoe UI Bold (TrueType)"=""
"Segoe UI Bold Italic (TrueType)"=""
"Segoe UI Italic (TrueType)"=""
"Segoe UI Light (TrueType)"=""
"Segoe UI Semibold (TrueType)"=""
"Segoe UI Symbol (TrueType)"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]
"Segoe UI"="YOUR_FONT_NAME"

• Replace “YOUR_FONT_NAME” with the name of the font you want to use as the default system font. Make sure the font name matches exactly as it appears in the Fonts folder of your Windows installation.
• This is what it looks like for our Comic Sans example:

• Save the file with a .reg extension, for example, “font_change.reg”.

• Double-click the .reg file to run it. You may receive a confirmation prompt asking if you want to make changes to the registry. Click Yes to proceed.

• You should see a confirmation message indicating that the changes have been successfully applied.
• Restart your computer to apply the new default system font.

Please note that modifying the Windows registry can have unintended consequences if done incorrectly. Ensure that you have a backup of your important data and consider creating a System Restore point before making any changes to the registry.
