As part of a raft of updates coming this spring, Microsoft will be bringing a new power management system that "reduces micro-latencies" and enhances overall system performance through a series of tiny performance bumps.
Microsoft released its first ever Insider Preview build from the Redstone 5 branch earlier this week.
If you have Windows 10 Pro FW, you can enable Ultimate Performance from the same Control Panel/Power options you'd use to set any other power plan. Where previously such users might have employed the High-Performance policy preset, which still included some performance and efficiency tradeoffs, the new Ultimate Performance goes further - but isn't (and might not be) available on battery powered systems.

The post does have Ultimate Performance as a feature specifically for Windows 10 Pro for Workstations, along with a change to what tiles are presented in the Start Menu by default, so this may or may not come to the consumer versions of Windows 10.
As such, it will "consume more power than the default balanced plan", and Microsoft now has the power policy set to be unavailable for battery-powered computers, as the company explained in their blog update. In Windows 10 Pro For Workstation, Microsoft went so far as to remove features from Windows 10, in favor of siloing them in a Windows distribution you can't even buy at retail.
In addition to the new Ultimate Performance mode, the next build of Windows 10 will also have some redesigned emoji, a new app permissions framework, and a whole host of bug fixes.
