Now in public preview: Fluent Emojis
For everyone dissatisfied with the new, static, flat/2D Fluent emojis shipped with Windows 11, there's an easy way to replace the "Segoe UI Emoji" font in your C:\Windows\Fonts folder with version 1.31 (shipped with an early version of Windows 11, featuring updated versions of Unicode 13.0 emojis, however still with the old Modern design, with a thick black outline).
I wrote some posts about this on Reddit.

Note: These instructions refer to Windows' own global emoji support. I don't use Microsoft Teams very much, and I'm not sure at all if it relies on the OS's font files or if somehow it has its own assets and stuff; it is possible that, after replacing the newer Fluent ones with the older Modern ones (for example, shown in Windows' emoji picker), they could still appear in many places in Teams -- in particular the animated emojis, which were heavily advertised as one of the highlights of then upcoming Windows 11 (and that promise never came to fruition, being exclusive to Teams, ugh) and which have no direct equivalent anywhere in Windows 10's old apps.
