The Windows 10 October 2018 Update, version 1809, continues to limp out of the door. While the data-loss bug that saw its release entirely halted has been fixed, other blocking issues have restricted its rollout. It has so far only been available to those who manually check Windows Update for updates, and even there, Microsoft has restricted the speed at which it’s distributed.
This particular speed bump has now been removed, and manual checking for updates is now unthrottled. That means a manual check for updates will kick off the update process so long as your system isn’t actively blacklisted (and there are a few outstanding incompatibilities that mean it could be).
