Windows 的隱藏 Ultimate Performance 電源計(jì)劃可通過命令啟用，但僅限支持的高性能設(shè)備使用。1. 首先確認(rèn)設(shè)備是否為高性能臺(tái)式機(jī)、工作站或特定品牌高端筆記本（如 Dell、HP、Lenovo、Surface Studio），因需硬件和固件支持；2. 以管理員身份運(yùn)行命令提示符，輸入命令 powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 啟用該模式；3. 前往“設(shè)置 > 系統(tǒng) > 電源與睡眠 > 其他電源設(shè)置”查看是否出現(xiàn) Ultimate Performance 計(jì)劃；4. 若未顯示，可能是 OEM 限制或缺少驅(qū)動(dòng)更新，需安裝廠商工具（如 Dell Power Manager）；5. 啟用后可在電源選項(xiàng)或任務(wù)欄電源圖標(biāo)中切換至該模式；6. 注意此模式會(huì)顯著縮短筆記本電池續(xù)航，增加發(fā)熱與風(fēng)扇噪音，建議僅在插電時(shí)使用；7. 該功能主要適用于 Windows 10/11 Pro 及 Enterprise 版本；8. 用戶還可基于此模式創(chuàng)建自定義電源計(jì)劃，調(diào)整處理器性能、散熱策略和 PCI Express 設(shè)置以最大化性能。啟用后可提升系統(tǒng)響應(yīng)速度和處理能力，但需權(quán)衡功耗與溫度影響。

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, gamers, and professionals using CPU- or GPU-intensive applications. This power plan minimizes latency and maximizes 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 (e.g., 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.
