It seems Microsoft is planning to push Windows 10 Build 10586.79 as next cumulative update to public running Windows 10 stable version on their PCs. Update KB3136562 has not only been reported by some as pushed to their PCs but also has been spotted on Microsoft’s update catalogue for both X86 and X64 devices.
Lucky few who could update their PCs before Microsoft removed KB3136562 report their Windows 10 versions upgraded to Build 10586.79. The build 10586.79 is not supposed to bring any new features but may pack lots of fixes and performance improvements. Microsoft is now planning to push new features in Redstone wave and Redstone Builds have started to roll-out to Insiders already.
The Changelog page for KB3136562 is yet unavailable but we may see it up soon.
