How to change the default fonts in Windows 10

You can change Windows 10 icon fonts with the following procedure:

  1. Press Win + R.

  2. Type regedit.exe and press Enter.

  3. Go to the following path:

     HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes
    

    You can find Segoe UI = Tahoma or similar on the right. Before changing the font value, note the default value somewhere.

  4. Find and double-click on Segoe UI to change its value. (in my case, it's Tahoma.)

  5. Enter the font name in Segoe UI's value data and press Enter.

  6. Restart to apply the changes.
