It goes without saying that the Windows 10 October update rollout has had a few snags. It was redacted, then halted and then paused for specific end-users with even more specific hardware setups.
As it seems now, the light is finally green and the Windows 10 October update is now available for everybody. Roughly a month or so ago Microsoft actually even relaunch the update, but even then some problems had risen. Microsoft even warned users to now scan for the new update and download/install it.
Most users need to update to the new build manually and that is still adviced. We expect that over time the rollout will be automated with auto updates. If you peek at the history updates for Windows 10 there is this new update today, now also including advanced users:
Rollout Status as of December 17, 2018: Windows 10, version 1809, is now fully available for advanced users who select "Check for updates" via Windows Update.
Let's hope all problems have been resolved, but enthusiasts can now search and install the update via their PC.
