Microsoft has officially announced the Windows 10 21H2 feature update (build 19044.1147) and released the first preview build to Insiders for testing.

While Windows 11 is the hot topic right now, most enterprise users will likely be staying with Windows 10 until the bugs are worked out of the new operating system.
