At the same time, Microsoft is syncing the Office 365 ProPlus release cycle with Windows 10. These releases will each be supported for 18 months.
So the next major Windows 10 update will arrive in September and Microsoft is expected to share more details about "Redstone 3" at its Build developers conference in Seattle next month.
Microsoft isn’t detailing exactly what its next major Windows 10 update will include, but the company recently started allowing Windows Insiders to start testing what is codenamed Redstone 3. The next Windows 10 update will include power throttling for background apps, and we’re expecting to see the return of the people integration into the taskbar that was originally scheduled for the Creators Update.Via: The Verge
