How to change the default System Font on Windows 7/10?

If you’re bored using the default system font on Windows 10 and want something new, you can change it to your desired font with a simple registry tweak. By doing registry changes, you can change the Desktop icons’ default system fonts (e.g., Recycle bin, This PC, etc.), title bar, message box, and others. Since this tweaking of changing the default System Font on Windows 10 involves registry tweaking, we recommend taking the registry’s backup and creating a system restore point. If something goes wrong, you can revert to the original state.

If you can recollect, on the older version (Windows 7 and earlier), changing the default system font was not a big issue. It was quite straightforward through personalization settings in the Control Panel. Because of some unknown reasons, Microsoft has removed these settings from the Windows 10 operating system. That means you can not change the default system font without registry tweaking or any third-party software. This post will guide you to change the default system font in Windows 10 OS by registry tweaking.
