Around 2 weeks ago, Microsoft wanted to give me another update(on my second computer), I got it. It was a disaster, the screen was black afterwards and the computer wouldn't boot even with a Repair disk or Restore Drive in. I had to unplug the power for a full minute to get it to boot. Thankfully, it booted OK then, but was (still?)at version 1809. I used StopUpdate10 to keep it from updating again for more than the 4 days Windows would give me. I undid that today and checked for an update, a Feature Update showed. I used MediaCreationTool1903 to make a flash drive installation fearing vagaries of the internet installation before. It started OK, but didn't restart at around 30% like previous updates. It didn't restart until after being at 89% for a long time. After the restart, I got a message box saying it thought I had been installing from installation media and giving me a choice of removing the media and keeping my programs or a clean install. I removed the flash drive and clicked on my answer. It went from "Processing update 0% to 27% quickly and changed that slowly afterwards, I got the second reboot at 64% and the 3rd reboot at 100%. After the reboot I got a normal feature update start and stopped worrying about the update. Because it rebooted at 90%, I thought I might have the Fall 2019 Update, but a winver check showed I had 1903.
