Time is misleading. Their implying that a computer needs 8 hours to finish an update. From the actual release: "One of the most impactful things we explored was how much time a device needs to be powered on and connected to Windows Update to be able to successfully install quality and feature updates. What we found is that devices that don’t meet a certain amount of connected time are very unlikely to successfully update. Specifically, data shows that devices need a minimum of two continuous connected hours, and six total connected hours after an update is released to reliably update. This allows for a successful download and background installations that are able to restart or resume once a device is active and connected." What the are saying is "you need to be able to reach the download server for at least 8 hours after an update drops in order to reliably install it."
