If your Windows computer feels sluggish or you notice high CPU usage, you’re not alone. Many users experience performance slowdowns over time due to software bloat, background processes, or outdated settings. Tuning your CPU performance can make your PC run faster and smoother. Here are seven proven, beginner-friendly methods to repair and optimize your Windows CPU performance.
Why Is My CPU Running Slow?
Before diving in, it’s helpful to understand that CPU slowdowns can be caused by too many programs running, outdated drivers, malware, or power settings that limit performance. The good news? Most fixes are simple and don’t require advanced knowledge.
1. What Programs Are Using My CPU? Check the Task Manager
One of the quickest ways to spot performance issues is with Task Manager.
Step 1: Right-click your taskbar and select Task Manager.
Step 2: Click the Processes tab.
Step 3: Click the CPU column header to sort by usage.
If you see any programs using a high percentage, and you don’t need them, select the program and click End Task. This can instantly free up CPU resources.
2. How Can I Reduce Startup Programs?
Too many apps starting with Windows can slow your PC. Here’s how to manage them:
Step 1: Open Task Manager (Ctrl + Shift + Esc).
Step 2: Go to the Startup tab.
Step 3: Right-click on unnecessary programs and select Disable.
This reduces the load on your CPU when your PC boots up.
3. Should I Update My Drivers?
Outdated drivers can cause compatibility issues and poor performance. Focus on updating your chipset and graphics drivers.
Step 1: Right-click Start and select Device Manager.
Step 2: Expand “Processors” or “Display adapters.”
Step 3: Right-click on the device and select Update driver.
Let Windows search automatically for updates. For graphics cards, visit the manufacturer’s website for the latest drivers.
4. How Do I Adjust Windows Power Settings for Better CPU Performance?
By default, Windows might use a balanced power plan, which can limit CPU performance to save energy.
Step 1: Press Windows + I to open Settings.
Step 2: Go to System > Power & sleep > Additional power settings.
Step 3: Choose the High performance plan.
This setting allows your CPU to use its full potential.
5. Can Cleaning My PC Improve CPU Performance?
Junk files, registry errors, and background clutter eat away at CPU resources. One of the easiest ways to clean and optimize your PC is by using Glary Utilities.
Why Glary Utilities?
Glary Utilities offers a one-click “1-Click Maintenance” feature that scans for and removes junk files, fixes registry errors, and optimizes background processes—all of which help your CPU run efficiently.
Step-by-step Example:
Step 1: Download and install Glary Utilities from the official website.
Step 2: Open Glary Utilities and click on 1-Click Maintenance.
Step 3: Check all categories and click Scan for Issues.
Step 4: After scanning, click Repair Problems.
This routine can free up system resources and boost your CPU performance with little effort.
6. How Do I Remove Malware That Might Be Slowing Down My CPU?
Malware and unwanted software often cause high CPU usage. Use Windows Security for a basic scan:
Step 1: Open Start, type Windows Security, and press Enter.
Step 2: Click Virus & threat protection.
Step 3: Click Quick scan.
For deeper cleaning, Glary Utilities provides a Malware Removal tool under its Advanced Tools, offering another layer of protection.
7. What About Windows Updates?
Regular Windows updates include bug fixes and performance improvements. Keeping your system up-to-date can prevent unexpected CPU spikes.
Step 1: Open Settings (Windows + I).
Step 2: Go to Update & Security > Windows Update.
Step 3: Click Check for updates.
Install any pending updates and restart your PC if needed.
