Windows 10 with changed System font

The Windows default font these days is Segoe UI, a fairly simple and no-nonsense typeface that’s used across many of Microsoft’s products. However, though some like this subdued style, others look to change Windows font to something with a bit more personality.

Thankfully, Microsoft does let you change Windows fonts, but it doesn’t make it particularly easy. This is likely because doing so can have unintended consequences, such as causing issues with your system clock.

We’re going to show you safely change the font in Windows 10 while fixing issues with the clock. We’ll also be walking you through how to restore default fonts in Windows 10 if you don’t like the changes.

How to Change the Font in Windows 10 with a Registry Key

As mentioned earlier, a change of Windows font isn’t as easy as a settings switch, but it’s still not too technical. All it requires is a text editor such as notepad and a font you like. First, though, you need to discover the full name for its font family.

Save the changes and restart.
