Microsoft will stop serving one of three types of Windows 10 updates, contending that the updates have been superseded by an even small and more efficient format.
Delta updates are due to disappear early next year, Microsoft said, with their demise effective Feb. 12, 2019, that month’s Patch Tuesday. Two formats will then remain: Full updates and express updates.
Delta updates are those that include only the components that have changed since the previous month’s update. Because delta updates include the full component that changed – say, the Notepad application – not only the individual files that make up the component, they are larger than express updates, which deliver only changed files. The bottom line, and what enterprise IT is most interested in, is that express updates are smaller than delta updates, which are in turn smaller than full updates.
