Microsoft is adding a new Power Plan policy to Windows 10 Pro workstations, to improve the performance of the computer. Along with Windows 10 Insiders Preview Build 17101, Microsoft previewed the same to the insiders in Fast Ring.

This change is expected to be available with the next major update of Windows 10, which is scheduled to release in Spring 2018.

Microsoft started rolling out the first Redstone 5 build (Windows 10 Insiders Preview Build 17604) to the Windows Insiders, who have opted into Skip Ahead. As there's a limited space into Skip Ahead and that's already filled, no new registrations are now being accepted.

If you are a Windows Insider in the Fast Ring, you already have a fresh preview build 17101, which is already started rolling out.
