Windows 10 is being developed as a service, meaning it receives new features on a regular basis.
Microsoft today released a new Windows 10 preview with Emoji 12.0. The update bumps Windows 10 from build 18841 (made available to testers on February 20) to build 18845. These builds are from the 20H1 branch, which represents the Windows 10 update that will arrive in the first half of next year.
Windows 10 is being developed as a service, meaning it receives new features on a regular basis. Microsoft has released six major updates so far: November Update, Anniversary Update, Creators Update, Fall Creators Update, April 2018 Update, and October 2018 Update.
Emoji 12.0 was finalized earlier this month. With the set of emoji to be included in Emoji 12.0 now decided by Unicode, Microsoft has added it to Windows 10. When you press WIN+(period) or WIN+(semicolon), all of these emoji will show up when you search for their corresponding keywords (otter, sloth, waffle, ballet shoes, and so on).
