For those on the Windows Insider Program, Microsoft is rolling out a fresh cumulative update dubbed as KB3206309 via Windows Update. This update pushes the build number to 14986.1001, as seen in the screenshot above.
If you are not able to download the update, you can install it via the cab files from the links given at the end.
In case you are not aware, Windows 10 Build 14986 is the latest Fast+Slow Ring build and since, Microsoft has already announced that no more builds are releasing this year, this is indeed a welcome update.
Microsoft has not provided any official change-log so far, but once it is available we will update the article.
