After releasing an RTM build last week 14393.5, the company is now internally testing a new Cumulative Build for Windows 10 PC and Windows 10 Mobile Redstone.
The build has been compiled on 25th July 2016 with version 14393.31. This could be another Cumulative Update to be released to the Insiders for Redstone.
Currently the company has not declared if any new features will be added, hence we expect this to be another cumulative build to fix some under the hood bugs and improve the overall performance of the OS.
We can say this could be the build which might be released to general public as an Anniversary Update. But this news is not yet confirmed by the company, hence take this with a pinch of salt.
If no new bugs are found then we expect this to be released sooner than later to all Redstone Insiders or even the General Public as AU.
