As promised last week, Microsoft has today dropped the first Windows 11 Preview Build for Insiders in the Dev Channel. Windows 11 Build 22000.51 is now available, introducing us to a new design and tons of new features. The company said that Insiders won't be able to see all of the new features that were showed last week right away since this is an early build.

"As we finalize the product over the coming months, we will work with you to validate the experience," Amanda Langowski and Brandon LeBlanc of the Windows development team wrote. "You will get to try many, but not all, of the new features we showed last week in this early preview."
