This tutorial will show you how to change the default system font for all users in Windows10 and Windows 11.
A font is a graphical representation of text that may include a different typeface, point size, weight, color, or design.
Windows 11 uses the Segoe UI font as the default system font. This font is used for icons, menus, title bar text, File Explorer, and more.
You must be signed in as an administrator to change the default system font.
Changing the default system font will not affect Microsoft Store apps and modern UI items like Settings and Start menu.
EXAMPLE: Default "Segoe UI" vs changed "Arial Bold" system font in File Explorer
