How to Fix Services Controller App High CPU Usage on Windows 11: Step-by-Step Guide

Experiencing high CPU usage caused by the Services Controller app on Windows 11 can slow down your computer significantly. This issue often leads to poor system performance and can be frustrating to resolve. Fortunately, there are simple steps you can follow to identify and fix the problem. This guide will walk you through the process in an easy-to-understand way.

We will start with basic checks and move towards more advanced solutions. Each step is explained clearly so you can follow along without any technical background. By the end, your system should be running smoothly again.

Let’s begin by understanding what might cause the Services Controller app to use so much CPU. Then, you will learn how to fix it step-by-step.

Remember, patience and careful following of instructions are key to solving this issue effectively.

Quick Note: Prerequisites and Initial Checks

Before diving into fixes, it’s important to perform a few quick checks. These will help avoid unnecessary troubleshooting and may even solve the problem immediately.

  • Restart your computer: Sometimes, a simple reboot clears temporary glitches causing high CPU usage.
  • Check for Windows Updates: Make sure your Windows 11 is up-to-date, as updates often include bug fixes that improve system performance.
  • Scan for malware: Malware can disguise itself as system processes and cause high CPU usage. Run a full system scan with Windows Defender or any trusted antivirus software.
  • Close unnecessary apps: Some background apps may conflict with services. Close apps you don’t need to free up system resources.

Step 1: Identify the Services Controller App Causing High CPU Usage

The first step is to confirm that the Services Controller app is actually the cause of the high CPU usage. To do this:

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click on the Processes tab.
  3. Look for Services and Controller app or similar entries like svchost.exe consuming a large percentage of CPU.
  4. If you find it, this confirms the issue.

Understanding which process uses high CPU helps avoid unnecessary fixes for unrelated problems.

Step 2: Restart the Services Controller App

Restarting the service can clear temporary errors and free up CPU usage. Here’s how to do it:

  1. Press Windows + R to open the Run dialog box.
  2. Type services.msc and press Enter. This opens the Services window.
  3. Scroll down and locate the service named Windows Modules Installer or TrustedInstaller (this is often associated with services controller activities).
  4. Right-click the service and select Restart.
  5. If the option is greyed out, select Stop first, then right-click again and select Start.

Restarting the service may stop the high CPU consumption temporarily or permanently if it was caused by a stuck process.

Step 3: Run the System File Checker (SFC) Tool

Corrupted system files can cause the Services Controller app to behave abnormally. The System File Checker repairs these files. To run SFC:

  1. Press Windows + S, type cmd, then right-click Command Prompt and select Run as administrator.
  2. In the Command Prompt window, type the following command and press Enter:
sfc /scannow

The scan will take some time to complete. It will automatically repair any corrupted files it finds. Restart your computer after the scan finishes.

This step is important because it ensures your system files related to services are intact and functioning correctly.

Step 4: Check and Repair the Windows Update Components

Since the Services Controller app is tied closely to system updates, corrupted update files can cause high CPU usage. To fix this:

  1. Open Command Prompt as administrator (see Step 3).
  2. Type the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

These commands stop update services, rename update folders (forcing Windows to create new ones), and restart the services. This can clear corrupted update caches causing high CPU usage.

Step 5: Disable Startup Programs That Might Interfere

Some startup programs may conflict with system services and cause high CPU usage. To manage startup items:

  1. Open Task Manager (Ctrl + Shift + Esc).
  2. Go to the Startup tab.
  3. Look for programs with high impact on startup and disable those you don’t need by right-clicking and selecting Disable.
  4. Restart your computer.

Reducing startup load can prevent conflicts that lead to high Services Controller CPU usage.

Step 6: Perform a Clean Boot to Troubleshoot Third-Party Conflicts

If the problem persists, a clean boot helps identify if third-party software is causing the issue. Here are the steps:

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check Hide all Microsoft services at the bottom.
  4. Click Disable all.
  5. Go to the Startup tab and click Open Task Manager.
  6. In Task Manager, disable all startup items.
  7. Close Task Manager and click OK in System Configuration.
  8. Restart your PC.

If the high CPU usage stops after a clean boot, this indicates a third-party app or service was causing the problem. You can re-enable services and startup programs one by one to find the culprit.

Alternative and Advanced Options

If the above steps do not resolve the issue, you can try the following advanced options:

  • Update device drivers: Outdated or faulty drivers can cause system instability. Use Device Manager to update drivers.
  • Reset Windows Update: Use the Windows Update Troubleshooter from Settings > Update & Security > Troubleshoot.
  • Perform a System Restore: Roll back Windows to a point before the issue started using Control Panel > Recovery.
