Due to complaints about the 1809 rollout, MS has a new format for Win 10 1903. If you click on the "check for updates" button, 1903 won't automatically download and install. Instead in Windows update you will be notified that 1903 is available, but there's a second button to click on that says "download and install". Win 1903 became generally available last week, but it hasn't shown up on the Windows update page for my two PCs. IIUC MS is slow-walking the rollout based upon their analysis of your machine's compatibility with 1903. Has anyone here had the 1903 build show up on their Windows update page?
