Windows 10 Insider Preview Build 21327 Releases

Microsoft recently launched Windows 10 Insider Preview Build 21327 to users in the Dev Channel and continues to make various improvements to the news and interest modules.

This news and interest module is the weather module on the right side of the taskbar that we mentioned earlier. When you click on the weather module, this news information window will pop up.

Although Microsoft has not developed any new features in this update, the Microsoft design team has updated the icons built into the system to conform to the Microsoft Fluent Design style.

According to the Microsoft design team, these system icons have been redesigned through the Microsoft Fluent Design system.

So when users update, they will find that the styles of icons used in many systems have changed, and the Microsoft design team has also updated the vector graphics built into the system.

These vector icons are mainly provided through the system font called Segoe Fluent Icons. The overall look of these vector icons is more concise and rounded.

After thorough testing, Microsoft may push this newly designed font to other versions, and other versions may also be able to update the vector graphics at that time.
