In this article, we will show how to change the default system font on Windows 11/10, including the way to restore the default system font using the Registry Editor. Before you proceed, one thing you must know is that without having proper skills, editing a registry is dangerous. It can damage your system permanently which might be irreversible. So, if you have a little knowledge of what you’re doing then you can skip it and ask a skilled person to complete the adjustment.
Change default System Font in Windows 11/10
Before you go ahead and use the steps, do remember to create a system restore point first.
To get started, open Notepad first. You can open it using the Run command. Simply press Windows+R keys to launch the Run dialog box, type Notepad in the text field, then hit Enter to open the Notepad app.
In the Notepad app, copy and paste the following text code:
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"="NEW_FONT"
Now, open the Settings app and click on the Personalization category.
In the left pane, select the Fonts tab. You will see a large collection of the font family on the right.
Select the font you want to use from the list and also note its Official name. For example – Book Antiqua.
Now replace “NEW_FONT” with the font name you have selected from the Settings page. Because I prefer the font name “Book Antiqua” to be used in the entire system so, you can see the above image, I have replaced the “NEW_FONT” with the Book Antiqua in the registry code.
After replacing the font name in the Notepad, click on the File menu and then select the “Save as” option. On the Save as page, switch “Save as type” to All Files.
Name the file, choose the preferred location of your file, and then click the Save button. The file name must have the .reg extension. For instance – I have named my file my_font. So, the name of my file with the .reg extension should be “my_font.reg”.
Now go to the location where the .reg file has been saved. Then right-click on it and select the Merge option from the context menu.
Click Yes and then hit the OK button to save the changes.
After performing the above steps, restart your computer and the new font will substitute in the entire system.
