Changes to default fonts on Windows: Quick fixes
If you’re not sure why your default system font on Windows has changed and want to change it back, follow the steps below in order. We recommend trying each step, even if you successfully change your font back to its original style, as malware could still be lurking around on your device.

An easy way to get your system font back to normal is to restore default font settings.

Remove recently installed or unfamiliar fonts
Your computer has a list of installed fonts it uses for different programs, but you can also install new fonts from the web.
If you’ve recently installed a new font, but it’s causing other font problems, like changing the default font for your whole system, it’s time to remove it. Changes can also happen if cybercriminals have installed a new font, so it’s worth checking and deleting any unfamiliar fonts.
To remove any fonts, head to Start > Control Panel > Appearance and Personalisation > Fonts > right-click any recently installed or unfamiliar fonts and select Delete.

Change your passwords
If you’ve experienced changes to your default font on Windows and nothing will fix it, chances are your PC has been infected with a virus or malware, and your online accounts and devices are at risk of being compromised.
