Glad to hear that.
...It is updating to (downloading)1903 right now but is stuck for 5 minutes on the 99% mark. Hopefully won't have a problem...
Sounds like you are using Windows Update to update to 1903. Yes, the step from 'downloading 99%' to 'Downloading 100%' takes a very long time. Don't worry, it should be fine. For what to expect next, see this post where I timed the various stages. I'm afraid you are in for a long wait, but be patient - it should (eventually) successfully complete the update. Yours should be a bit faster than mine as you have an SSD.
How long does the 1903 upgrade take using Windows Update?
