The Windows 10 May 2021 Update is rolling out now. The update doesn't include any major changes but does include some new business-critical additions. The Windows 10 May 2021 Update also comes with the new Microsoft Edge preinstalled. Microsoft released the Windows 10 May 2021 Update today, which is also known as Windows 10 version 21H1. While it is a feature update, the Windows 10 May 2021 is relatively small in terms of new features and noticeable changes. Microsoft designed the Windows 10 May 2021 Update to be minor since a much more significant update, which is codenamed Sun Valley, is on the way later this year. The biggest change in this Windows 10 update is that it comes preinstalled with the Chromium-based Microsoft Edge rather than the legacy version of Edge. The new Edge has been available for over a year, but this is the first time that it's been preinstalled in Windows 10.
