For months I didn’t get notification for major updates, but as soon as I made 30 gb space free, and clicked update, it was there.
First update to 1909 failed via normal update, so I tried using the useless update assistant all but that failed as well.
Finally I created bootable usb via the Microsoft media creation tool and used that… In that don’t format the primary drive, instead choose the custom fresh install option which moves old Windows files in another folder u can later delete.. This is safer…. But user and app data and apps will be gone, so take backup
