The hidden Ultimate Performance power plan for Windows is enabled via commands, but only for supported high-performance devices. 1. First, confirm whether the device is a high-performance desktop, workstation or a specific brand of high-end notebook (such as Dell, HP, Lenovo, Surface Studio), as hardware and firmware support is required; 2. Run the command prompt as an administrator and enter the command powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 to enable this mode; 3. Go to "Settings> System>Power and Sleep>Other Power Settings" to see if the Ultimate Performance plan appears; 4. If it is not displayed, it may be OEM restrictions or lack of driver updates, and manufacturer tools (such as Dell Power Manager) are required; 5. After activation, you can switch to this mode in the power options or the taskbar power icon; 6. Note that this mode will significantly shorten the laptop's battery life, increase heating and fan noise, and it is recommended to use it only when plugged in; 7. This feature is mainly suitable for Windows 10/11 Pro and Enterprise versions; 8. Users can also create custom power plans based on this mode, adjust processor performance, cooling policies, and PCI Express settings to maximize performance. When enabled, the system response speed and processing capacity can be improved, but the power consumption and temperature impact need to be weighed.

Windows includes several built-in power plans like Balanced, Power Saver, and High Performance, but there's also a hidden Ultimate Performance mode designed for workstations and high-end PCs—especially useful for content creators, games, and professionals using CPU- or GPU-intensive applications. This power plan minimizes latency and maximums performance by optimizing system resources.

Here's how to enable the Ultimate Performance power plan in Windows:

? Check if Your System Supports Ultimate Performance

Not all PCs support this mode. It's typically available on:

• High-performance desktops
• Workstations
• Some high-end laptops (especially from Dell, HP, Lenovo, or Microsoft Surface Studio)

It requires specific hardware and firmware support (especially for power delivery and thermal management). If your system doesn't support it, the plan won't appear even after enabling it via command.

? Enable Ultimate Performance via Command Prompt

Since this plan is hidden by default, you need to use the Command Prompt to enable it.

Steps:

1. Open Command Prompt as Administrator

   • Press Win S , type cmd
   • Right-click on Command Prompt and select Run as administrator

2. Run the following command:

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

   This command activates the Ultimate Performance power plan using its GUID.

3. Check if it's enabled

   • Open Power Options: Press Win I → Go to System → Power & sleep → Additional power settings
   • You should now see Ultimate Performance in the list of power plans.

? If you don't see it, your PC's hardware or OEM configuration may not support it. Some manufacturers require additional drivers or firmware updates (eg, Dell Power Manager, Lenovo Vantage, or Surface drivers).

?? Switch to Ultimate Performance

Once enabled:

• Go to Control Panel > Hardware and Sound > Power Options
• Select the Ultimate Performance plan
• Or right-click the battery/power icon in the taskbar → Power modes → choose Ultimate Performance

?? Things to Keep in Mind

• Battery Life Impact : On laptops, this plan drastically reduces battery life . It's best used when plugged in.
• Heat and Fan Noise : Expect higher temperatures and louder fans due to full CPU/GPU utilization.
• OEM-Specific : Some manufacturers hide or rename this plan. For example, Dell calls it “Performance” or “High Performance” in its own power tools.
• Not Available on All Windows Editions : It's primarily supported in Windows 10 Pro, Enterprise, and Windows 11 Pro/Enterprise .

? Optional: Create a Custom Power Plan Based on Ultimate Performance

You can tweak settings like display timeout, sleep mode, or processor power management:

1. Go to Power Options
2. Click Change plan settings next to Ultimate Performance
3. Then Change advanced power settings
4. Adjust settings like:
   • Processor power management → Maximum processor state (set to 100%)
   • System cooling policy → Active (for performance)
   • PCI Express → Link State Power Management → Off

Basically, enabling Ultimate Performance is simple if your hardware supports it—just one command unlocks it. But it's not a magic boost for every PC. Use it when you need every bit of performance and are plugged into AC power.
