QUOTE:  Microsoft is hard at work on the next version of Windows 10, known as version 20H2 and launching later this year with new changes and enhancements. While this next version is in development, we’re going to assemble all of the changes and new features added to Windows 10 version 20H2 through the Windows Insider Program here into one convenient list.  Just like the Windows 10 November 2019 Update, this upcoming release isn’t a full feature update. That means when it’s ready, the update will sit on top of the May 2020 Update instead, equating to a much smaller download and install period.

The new Microsoft Edge is now preinstalled. The touch experience is more optimized when in desktop mode
