Microsoft is now rolling out a cumulative OS update for those on Windows 10 for PC and tablets. The update, like ones in the past, are cumulative security and bug fixes that address ongoing issues with the operating system.
The OS update will happen on its own. However, you can also force check to get it now. Head into All Settings > Update & security > Check for updates. The update is listed as kb3124262.
If you are a Windows Insider for PC, you will not see this update, but there is usually a separate one that also delivers security and bug fixes that apply to the latest rs1_11102 release from January 21.
We'll update this article with any new information about the update if Microsoft releases any notes.
Update: Microsoft has now posted the KB article for this update, however there is nothing substantial in it for notes
