Microsoft have released a new Windows 10 Fall Creators Update for Windows Insiders to test. The new build is 16278 and is for the current development branch of Windows 10 and not for the skip ahead option. This build focuses on fixing issues as Microsoft prepare to release the update to Windows consumers, so there are no new features but there are plenty of fixes.
In this video I take a look at the changes. You can read the full release notes here.
