Windows 11 is finally, definitely official after being announced at Microsoft’s big event on June 24.

Microsoft CEO Satya Nadella made sure to tell everyone at the event that this was the first version of a new era for Windows.

A very early build of Windows 11 had leaked before the event, showcasing a refreshed look and a new name, we finally got to see the new user interface and new features officially. Now though, the test build has been released to Insiders, ready to give the company feedback.

While Microsoft had in the past said that Windows 10 was going to be the only version of its operating system for years to come, it’s now been around for six years, and this new update brings significant features to help justify the jump to a new number.
