Microsoft has released Windows 11 Insider Preview Build 22478 for Windows Insiders in the Dev channel, who are testing the future versions of this new operating system. This build brings the new Fluent emoji to the Insiders community along with several improvements and fixes. Here is everything that is new and fixed with Windows 11 Build 22478.

Back in July, the Microsoft Design Team announced refreshed and new Fluent-designed emoji that would roll out across all of Microsoft 365 – including Windows. We are excited to be giving Windows Insiders a “first look” at how our new emoji design will look in Windows 11 starting with today’s Dev Channel build.
