How to Change System font using Registry file in Windows 10?

In Windows 10 there is no direct setting to change the system’s default font. If you want to change it then you need to use the registry file. This article will guide you to Change System font using Registry file in Windows 10.

Change System font using Registry file:

Open Notepad and copy and paste the below-mentioned Registry code.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionFonts]
"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)"=""

"Segoe UI"="YOUT-FONT-NAME"

Replace YOUT-FONT-NAME with the actual font name, If you don’t know which font is installed and the name of the font. Then you can get it from Font Setting.

Open Windows Settings by Pressing Windows + I and click on Personalization.

On the Personalization page from the left-hand side click on Fonts, Under the Fonts page, you can see the list of available fonts on your Windows 10 system.

Choose any Font and Pick the name, For example I choose Agency FB. Now replace the YOUR-FONT-NAME with Agency FB.

And save the Notepad on Desktop and name it as ChangeFont.reg and click on Save.

Now Double click on the ChangeFont registry file, now you will get a popup click on Yes to merge the Registry file.
