How to Disable CPU Throttling in Windows 11 25H2

With the release of Windows 11 25H2, Microsoft has refined how CPU throttling works. The system now uses AI-based workload detection and improved power efficiency models to dynamically adjust CPU performance.

While this is great for battery life and thermals, it can limit performance in demanding tasks like gaming, video editing, or development workloads.

If you’re a power user, disabling CPU throttling can help unlock your system’s full potential.

What Is CPU Throttling in Windows 11 25H2?

CPU throttling (or Dynamic Frequency Scaling) is a system-level feature that reduces processor speed to:

• Save power
• Reduce heat
• Extend battery life

In Windows 11 25H2, this system is more advanced thanks to:

• AI-based background task prioritization
• Improved “Efficiency Mode” for apps
• Smarter hybrid CPU (P-core / E-core) scheduling

Types of CPU Throttling

• Thermal Throttling: Reduces speed when temperatures get too high
• Power Throttling: Limits CPU usage to save energy

👉 New in 25H2: Windows may throttle background apps more aggressively, even on powerful desktops.

Method 1: Use the New “Best Performance” Mode (Updated for 25H2)

Windows 11 25H2 simplifies power control through Settings.

Steps:

1- Press Windows + I

2- Go to System → Power & battery

3- Find Power mode

4- Select Best performance

What changed in 25H2?

• “Best performance” now overrides AI-based throttling behavior
• Reduces background app limitations
• Improves performance consistency in games and heavy apps

Method 2: Enable Ultimate Performance Power Plan

The Ultimate Performance plan still exists in Windows 11 25H2, but it’s hidden by default.

Enable it:

1. Open Command Prompt as Admin
2. Run:

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

3- Go to Control Panel → Power Options

4- Select Ultimate Performance

👉 This disables most power-saving features, including CPU throttling behavior.

Method 3: Set CPU Usage to 100% (Still Works in 25H2)

1- Open Control Panel → Power Options

2- Click Change plan settings

3- Select Advanced power settings

4- Expand Processor power management

5- Set:

• Minimum processor state → 100%
• Maximum processor state → 100%

This ensures your CPU always runs at full clock speed.

Method 4: Disable Power Throttling via Group Policy (Pro Users)

Works on Windows 11 Pro / Enterprise.

1. Press Windows + R, type gpedit.msc
2. Navigate to:

Computer Configuration → Administrative Templates → System → Power Management → Power Throttling Settings

Open Turn off Power Throttling

Set to Enabled

👉 This disables Windows background throttling globally.

Method 5: Disable CPU Throttling via Registry (Home Users)

⚠️ Be careful when editing the registry.

1- Open the Run dialog by pressing Windows + R, type regedit, and press Enter to open Registry Editor.

2- To back up the registry, click on ‘File’ in the top menu and select ‘Export. Save the backup file to a safe location.

3- Navigate to the following path or paste it into the address bar:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

4- Right-click on the ‘Power’ folder, select ‘New’, and then click on ‘Key’.

5- Name the new key ‘PowerThrottling’ and press Enter.

6- With the ‘PowerThrottling’ key selected, right-click in the right pane, choose ‘New’, and select ‘DWORD (32-bit) Value’.

7- Name the new DWORD value ‘PowerThrottlingOff’ and press Enter.

8- Double-click on ‘PowerThrottlingOff’, set the ‘Value data’ to 1, and click ‘OK’. This action disables CPU throttling.

9- Restart your computer to apply the changes.

Method 6: Disable “Efficiency Mode” for Apps (New in 25H2)

Windows 11 25H2 aggressively uses Efficiency Mode in Task Manager.

Disable it:

1. Open Task Manager (Ctrl + Shift + Esc)
2. Go to Processes
3. Right-click an app
4. Disable Efficiency mode

👉 This prevents Windows from throttling that app in the background.

Method 7: Set High Priority for Critical Apps

1. Open Task Manager
2. Go to Details tab
3. Right-click app → Set priority → High

This forces Windows to allocate more CPU resources.

Method 8: Keep Background Apps Active

Go to Settings → Apps → Installed apps

Select your app → Advanced options

Set Background permissions → Always

This prevents background throttling in 25H2.

Method 9: Optimize Cooling Instead of Fighting Throttling

Sometimes throttling is necessary.

Instead of disabling it completely:

• Clean dust from fans
• Use a cooling pad (laptops)
• Improve airflow
• Replace thermal paste (advanced users)

👉 Less heat = less throttling automatically

Should You Disable CPU Throttling?

Disable it if you:

• Game regularly
• Edit videos or photos
• Run heavy software (AI, dev tools)
• Use a desktop with good cooling

Keep it enabled if you:

• Use a laptop on battery
• Want better battery life
• Prefer silent operation

Final Thoughts

Windows 11 25H2 makes CPU throttling smarter—but also more aggressive.

For casual users, it’s great.
For power users, it can feel limiting.

The good news? You still have full control.

👉 With the right settings, you can unlock maximum CPU performance and get the most out of your hardware in 2026.
