Microsoft testing a new cumulative update for the production version user (non-windows insider). The next new cumulative update would be KB3197954.
Last week Microsoft released a new build as to the production version user as a part of the Tuesday patch witch was build 14393.321. And the new build which is expected to release after next week will have many enhancement over the last public build.
Since build 14393.351 is a cumulative update then of course it will not bring any new features but it surely bring many improvements and bug fixes. Well, of course, build 14393.351 is just hit the insider in the Slow and Release Preview rings. So it will soon available for the production user.
However there is no official change-log available available for build 14393.351 yet. But you keep an eye on this page or on Windows Latest, we will update this post as soon as we will have an official change-log for build 14393.351.
Next Patch Tuesday is very far, so hopefully it arrives before the November patching cycle due on the 8th of the month. Build 14393351 will be available for both PCs and Mobile.
Note : Some insider in slow and release preview ring can’t cumulative update build 14393.351 on PC.
