Earlier this year, Microsoft accidentally
confirmed that it was working on UI improvements for
Windows 10 and references to inactive codes were spotted in the
preview builds. Now, we’re finally seeing those internal codes
put to good use as a fresh update has rolled out to testers in
the Insider program to give the desktop platform a polished new
In the recent preview builds, there are two primary changes.
For one, rounded corners are now more noticeable.
Microsoft has also introduced new icons that you’ll find
almost everywhere. This extends to the Settings app, Control
Panel, File Explorer, and various app windows.
As with most Windows 10 preview builds, there’s nothing all
that major in this week’s update. The overall layout of the
operating system is roughly the same as it’s been since the
last big feature update (Creators Update). However, Microsoft
has spent some time updating the basic UI elements to make
things look a bit more modern.
Microsoft is planning to update the default font system.
As you may be aware, Windows 10’s default system font is “Segoe
UI” and it is used across all applications, such as Control
Explorer, Explorer, Settings, etc.
Segoe UI looks pretty nice. However, Microsoft believes that
there’s still room for improvements.
In the next update, Microsoft is updating the default Segoe UI
to include an “optical axis”, which should allow the fonts to
scale seamlessly on various form factors. For instance,
Microsoft seems to have improved the legibility at small sizes,
and outlines will look better at display sizes.
By default, Windows 10’s Segoe UI is designed to work at 9pt
font size. Font expressions are limited at large sizes and the
current implementation also lacks legibility at sizes smaller
In the next version, Microsoft’s Segoe UI font UI will
dynamically adjust across all your apps and devices and offer
great legibility at different sizes, which includes fonts
smaller than 9pt. The style and outlines will also get better
at large sizes.
These changes would be noticeable in the Settings and other
For example, as you can see in the above screenshot, the
“Settings” text on the app title bar does look cleaner than the
current font on the right side.
It’s worth noting that Microsoft is slowly moving to the new
Segoe UI Variable and it will be implemented over time. At the
moment, the new fonts are noticeable when you look closely at
the title bar of the UWP apps.
