How to Fix Low CPU Speed on Windows 10/11?

Fix 1: Change Power Options

At first, you can fix CPU not running at full capacity or speed by setting the processor performance state to maximum. Here’s how to do it:

Step 1. Type control panel in the search bar and hit Enter.

Step 2. Expand the drop-down menu of View by and select Large icons.

Step 3. Click on Power options > Change plan settings > Change advanced power settings.

Step 4. Expand Processor power management > click on Maximum processor state > select 100%.

Step 5. Expand System cooling policy and make sure it is active to avoid overheating.

Step 6. Save all the changes you’ve made.

Fix 2: Update or Disable Intel Power Management Driver

Intel Power Management can control CPU and Fan speed when it needs to save battery, preventing CPU from running at full speed. In this case, you can disable it temporarily. Here’s how to do it:

Step 1. Power off your computer > turn it on > press the Power button again when the Windows logo appears on the screen.

Step 2. Repeat this process 2 or more times until the Automatic Repair screen appears. Tap on Advanced options to enter Windows Recovery Environment.

Step 3. Navigate to Troubleshoot > Advanced options > Command Prompt.

Step 4. Type cd drivers and hit Enter to locate the C:\Windows\System32\drivers folder.

Step 5. Run the following command to rename the Intelppm file.

ren intelppm.sys intelppm.sys.bak

Fix 3: Disable Intelppm Service

Another way to disable Intel Power Management is to modify relevant registries. Here’s how to do it:

Warning:

Before making any changes to Windows Registry, it is highly recommended to back up the registry database in case anything goes wrong in the process.

Step 1. Press Win + R to open the Run box.

Step 2. Type regedit and hit Enter to launch Registry Editor.

Step 3. Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\intelppm

Step 4. In the right pane, right-click on Start > change its Value data to 4 > hit OK.

Tips:

After changing the Value data to 4, your CPU will run at full speed all the time. If you just want the CPU to work at full speed only when needed, change the Value data to 1.

Step 5. Quit Registry Editor and then restart your computer to see if CPU not running at full capacity is still there.

Tips:

Overheating might lead to a sudden power outage. What’s worse, your data might be lost by accident. To protect your data, it is a good idea to create a scheduled backup with a free PC backup software – MiniTool ShadowMaker. The backup process is super easy to follow and you can restore your files to minimize losses when accidents occur.
