[How to] Enable Ultimate Performance power plan in Windows 10

Aimed at workstations and servers, the Ultimate Performance power mode is more full-throttle than the High Performance plan. It is generally not shown in your power settings unless you’re using Windows 10 Pro, but in other versions you can add it via a simple terminal command. It may help eliminate latency in certain tasks that you’ve otherwise been unable to tackle, in addition to improving gaming performance, audio processing, or anything else where you need latency-free real-time performance. This power plan is not recommended while running on battery power.

To enable it, open a command prompt as admin (right-click on Command Prompt icon and choose ‘Run as Admin’) and enter the following command:

powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

You should now be able to choose it in your list of power plans. If you don’t know how to switch modes, go to Start > Settings > System > Power & Sleep, then click on “Additional power settings” on the right below “Related settings.” You should now see it there along with your Balanced, Power Saver and High Performance modes.
