for those running Build 18362.10024 and Release Preview channelsWindowsInsider user, today we released an update to 19H2 Build 18363.418. If you are currently in Build 18362.10024 and still on the Slow channel, you will not receive this update.

You need to follow the recommended steps in the following blog post and switch to the Release Release channel to get today's final version of 19H2. If you are still in the Slow channel version, you will upgrade to the 20H1 development channel in the near future. It is time to check your Windows Insider channel settings carefully.
