The next 6 month update to Windows 10 is just a small patch that will be delivered via Windows Update. Those in the Windows Insider Slow Track should have it already and it'll be about a week or two until it is released via the Mainstream Track. Although many are calling this "Version 1909", the changes are very minor and the update process won't take much longer than a standard cumulative Windows Update. Moreover the Version remains at Version 1903.
