Microsoft has just released a new cumulative update for Windows 10, but for the moment, it doesnít seem to be available through the usual Windows Update distribution system.
At this point, the only way to get cumulative update KB3140742 is to manually download it, so you can click the links at the bottom of the article to do so. Make sure you get the right version for your computer and please note that KB3140742 is only available for Windows 10 1511 (November Update), so users still on the RTM build (10240) wonít be able to install it.
Microsoft is yet to publish a KB article for this update, so itís not yet clear what it includes, but most likely, itís all about bug fixes and performance improvements. The recently released Windows 10 update history page doesnít provide any information on update KB3140742 at the time of writing this article.
