Fix: CPU is not running at full speed in Windows 11 / 10

CPU is the main brainpower for your system, but what if you see that the CPU is not running at its full capacity even when you are running a high power process. In most cases, a machine is set to balance performance mode or power-saving (if it is a laptop) mode by default. So, follow these easy solutions to set your CPU to offer the peak performance once it is required.

Fix 1 – Disable Ipppm using the registry

The Intel Power Management driver can cause this problem. You can use the registry editor to disable the Intel Power Management driver.

1. At first, type “regedit” in the search box.

2. Then, click on the “Registry Editor” to access it.


Regedit New Search Min


Warning – Registry Editor is a very sensitive place. A simple unaccounted alteration may lead to a fatal system error. So, please create a system backup just to be cautious.

When the Registry Editor opens up, tap on “File“. Then click on “Export” to create a new registry backup on your system.


Export Registry Windows 11 New Min


3. Then, go here –



4. Now, on the right-hand side, double click on the “Start” value to modify.


Start Min


5. At the next step, set the value to “4“.

6. Then, click on “OK“.


4 Ok Min


Once you have done this, just close the Registry Editor and restart your system.

Test the CPU performances in the Task Manager.


NOTE – If the Registry Editor is blocked or you can’t use it, you can use th terminal to disable the intelppm service.

1. Type “cmd” in the search box.

2. Then, right-click on the “Command Prompt” and tap on “Run as administrator“.


Cmd Search New Min


3. Once the terminal opens up, type this command and hit Enter.

sc config intelppm start= disabled


Intelppm Disabled


This will stop the intelppm service from starting up once your system starts up.

Once you have executed the command, close the terminal.

After that, reboot the system and test the CPU performance.



Fix 2 – Choose the High Performance

The easiest solution you can opt for is to use the High-Performance mode.

1. At first, press the Windows key+R keys together.

2. Then, write this line and hit Enter.



Powercfg Min


3. When the Control Panel opens up, tap on the “Show additional plans“.


Show Adittional Plans Min


4. After that, select the “High Performance” mode.

[NOTE – You can also use the “Ulitmate Performance” mode if you have enabled it. Want to enable this hidden power plan on your system, follow the steps mentioned in our guide.]


High Performance Min


Once you are done, try running a high load process on your system and test whether the CPUs are offering peak performance.


Fix 3 – Restore the default plan settings

Some users have claimed to solve this issue simply by restoring the default settings of the power plan they are using.

1. Just, right-click on the Windows icon and tap on the “Run“.

2. Then, type this code and hit Enter.



Powercfg Min



3. Then, look for the plan you are currently using.

4. Next, tap on “Change plan settings” to access it.


Change Plan Settings Min


5. Now, in the next window, tap on “Restore default settings for this plan“.


Restore Default Settings Min


6. You will see a warning message. Just tap on “Yes” to confirm it.


Yes Min


This will reset the power plan settings to their original settings. Now, play a game or run a power-hungry process to check whether the CPU is running at full speed.


Fix 4 – Set the processor to the maximum state

You should set your processor to run at the maximum state.

1. At first, press the Windows key+R keys together.

2. Then, type this code and hit Enter.

control.exe powercfg.cpl,,3

Power Option Powercfg New Advanced Options Min

3.  When the Power Options window opens up, expand the “Processor power management” settings.

4. Then, click on the “Maximum processor state“.

5. Next, set the “Setting:” value to “100“.

[If you are using a laptop, you will notice two options. Set “On battery:” and “Plugged in:” both settings to “100“.


Maximum Processor State 100 Min


6. Now, expand the “System cooling policy” settings.

7. Set it to “Active” settings.

[Just like before, if you are enacting this on a laptop, toggle “On battery:” and “Plugged in:” both settings to “Active“.]


System Cooling Policy Active Min


8. Once you are done, tap on “Apply” and “OK” to apply and save this change.


Apply Ok Min Min


Once you are done, close the Power Options window. Then, check the CPU performance from the Task Manager.

Fix – 5 Disable the Intel PM driver

If altering the registry doesn’t work, you have to rename the driver itself using a terminal command.

1. At first, press the Windows key+R keys together.

2. Then, type “cmd” and press Ctrl+Shift+Enter together to open the terminal with administrative rights.


3 Run Cmd Optimized


3. Once the terminal appears, copy-paste these commands one at a time and tap the “Enter” key.

CD C:\Windows\System32\driver
ren intelppm.sys intelppm.sys.bak

Cd Drivers


This will rename the existing intelppm driver, which in turn will disable the driver.


Fix 6 – Clean boot the system

Clean booting the system will isolate all third-party apps and services.

1. At first, press the Windows key+R keys together.

2. Then, type this command and hit the Enter key.



Msconfig New Min


3. In the System Configuration window, go to the “General” tab.

4. Here, tap on the “Selective startup” option and then check the “Load system services” and the “Load startup items” options.


Selective Startup Min


5. After that, tap on the “Services” section.

6. Here, you have to tick mark the “Hide all Microsoft services” box.

7. Next, tap on the “Disable all” option to disable all the third-party apps.


Disable All Min


You have just removed all the third-party apps from interfering.

8. Finally, click on “Apply” and then on “OK“.


Apply Ok Min

You will notice a prompt has appeared to restart your machine.

9. Just, click on “Restart” to reboot your system immediately.


Restart Min


This will restart the system without all the third-party apps running in the background.

Try running a CPU stress test online and check whether it is offering high performance.
