In November of 2018, Microsoft unveiled a refreshed line of graphics it had created with the new Fluent aesthetic Design for Windows 10 and beyond.
In December of 2019, announced that it had Fluent redesigns for all Windows 10 icons. As of yesterday, the company began releasing some of these icons, starting with Windows Insiders.
The first applications that acquired new appearance include them Calculator, Groove Music, Mail, Voice Recorder, Alarms & Clock, Movies & TV, and Calendar, according with The Verge, and more will follow.
The old Windows icons have been around for years, and even when Microsoft began adopting the minimalist pictograms of the Metro design era, it did not redesign all the Windows icons, leaving us with the old ones.
Fluent Design was first introduced at Microsoft's Build 2017 conference, showing us an interesting new stylistic direction from the company. Combines all lighting elements, movements, depth, hardware and scale and creates customizable assets that work across devices (PCs, phones, TVs, VR).
The last video Microsoft's push for its new unified Office app gives you a good idea of the aesthetic direction the company is headed.
Microsoft has promised to change all Windows 10 icons, so it's only a matter of time before the process is complete.
