Ultimate Performance mode for Windows 10 is enabled via the command line and is only available for high-performance devices. 1. First, run powercfg -l through the administrator command prompt to confirm whether the mode already exists; 2. If not, you can use the powercfg -duplicatescheme command to add it manually; 3. After adding, switch to this mode through the power option or command; 4. Pay attention to high power consumption, high heat generation and noise issues when using it. It is recommended to use it only when extreme performance is required.

The Ultimate Performance mode for Windows 10 is a hidden power plan designed for high-performance needs and is suitable for high-end PCs or workstations. It provides a more extreme performance release than "High Performance" mode, but is not an option to display by default. Here are a few ways to enable it.

How to check if Ultimate Performance mode is supported

Not all devices can see this mode, and it is usually pre-installed on computers equipped with high-performance hardware (such as desktop-level CPUs, high-end graphics cards). You can confirm by:

• Open a command prompt (run as administrator) and enter:

   powercfg -l

• Check whether there is a GUID corresponding to Ultimate Performance in the output result. If so, it means your system already includes this power plan.

  

If you don't see it, don't worry, there are methods below that can be added manually.

How to manually add Ultimate Performance mode

If your computer does not have this mode preinstalled, you can create it by importing the registry or copying an existing configuration. Recommended command line operation:

1. Open a command prompt (administrator)

2. Enter the following command:

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

   This GUID is the template ID corresponding to Ultimate Performance in Windows.

3. Run powercfg -l again to confirm whether it has been added successfully.

This will allow you to add Ultimate Performance mode to your power options.

How to switch to Ultimate Performance Mode

After the addition is complete, switching is very simple:

• Open "Control Panel" → "Hardware and Sound" → "Power Options"
• Find "Ultimate Performance" in the list
• Click the corresponding "Change Plan Settings" on the left to further adjust the screen closing time, etc.
• If you do not want the system to automatically switch power mode, it is recommended to set other plans to non-default state

You can also use the command line to quickly switch:

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

What should you pay attention to when using it?

While Ultimate Performance can squeeze out hardware performance, it also has some side effects:

• ? The power consumption is higher, and the battery life of the laptop will decrease significantly
• ?? Fan speed increases, noise may increase
• ? Long-term high load operation may lead to increased heat generation, so pay attention to the heat dissipation environment

Therefore, it is recommended to enable it only when extreme performance is required (such as rendering, gaming, and large software running). "Balanced" mode is still recommended for daily use.

Basically that's it. The operation is not complicated, but it is indeed easy to be ignored, especially the hidden power plan. If you are a user who pursues performance, you might as well give it a try.
