Threat and vulnerability information about a new revision of Windows becomes available on the second Tuesday of each month. Windows Autopatch assesses that information shortly afterwards. If the service determines that it's critical to security, it may be expedited. The quality update is also evaluated on an ongoing basis throughout the release and Windows Autopatch may choose to expedite at any time during the release.

At GA Autopatch doesn't support customer lead expedite but we have heard asks for that feature from customers before.
