Want to know how to check PC health in Windows? Even a well-maintained Windows PC can become slower over time. Too many apps, low storage, outdated drivers, malware, or hardware issues can all affect how well your computer runs. The good news is that you don’t need to be a computer expert to check your PC’s health.
Windows already includes several built-in tools that help you understand your computer’s condition. These tools can show if your storage is running low, whether your battery is wearing out, if your system has security issues, or if hardware is causing performance problems.

In this article, we’ll discuss why we should check PC’s health regularly. Then, you’ll learn the top 10 ways to check PC health in Windows and what each tool tells you.
Why You Should Check Your Computer Performance in Windows
Many of the people have the habit of only looking on our computer only when your system starts freezing or becoming slow. Instead, if we check our PC’s health regularly, it helps us catch small issues before they become serious.
A routine health check can help you:
- Improve overall performance
- Detect hardware problems early
- Free up storage space
- Increase battery life
- Keep Windows secure
- Reduce crashes and errors
- Extend the life of your computer
A few minutes of routine checkup of your computer on a monthly basis can make a difference; you don’t need to perform a complete diagnostic every day.

10 Ways to Check Your PC Health In Windows
Windows provides several tools for checking different aspects of your computer. Some of the tools give you a quick overview, while others provide a detailed information on troubleshooting.
1. Try Microsoft’s PC Health Check Tool
One of the easiest ways to check your computer is by using the PC Health Check app from Microsoft.
If it is already installed, open the Start Menu, search for PC Health Check, and launch the application. If it isn’t available, Windows will usually guide you to install it.
This tool gives a quick overview of your computer.
It lets you check:
- Windows update status
- Available storage
- Battery health (for laptops)
- Startup performance
- Device specifications
- Windows 11 compatibility
Instead of showing complicated technical details, the app uses simple indicators that make it easy to understand whether everything is working normally.
What to do if you find issues:
If the app reports low storage, remove unnecessary files or uninstall programs you no longer use. If startup time is high, disable programs that automatically launch when Windows starts.
If updates are pending, install them as soon as possible to improve stability and security.
2. Check Windows Security
A healthy PC is not just about speed. Security also plays an important role.
Windows includes a built-in security feature that helps keep your system protected against common online threats.
To open it: Start → Windows Security
Inside, you’ll find several sections that monitor different parts of your computer.
These include:
- Virus and threat protection
- Firewall and network protection
- Device security
- Account protection
- App and browser control
- Performance and device health
If everything is working correctly, you’ll mostly see green check marks. If Windows detects an issue, it usually explains what needs attention and provides a direct link to fix it.
3. Monitor CPU, Memory, and Disk Usage
Sometimes a computer feels slow simply because one program is using too many resources.
The easiest way to find this is with Task Manager.
- Press: Ctrl + Shift + Esc
- Select the Processes tab.
Here you’ll see how much of your computer’s resources are being used.
Pay attention to:
| Resource | Healthy Range |
| CPU | Usually below 20% while idle |
| Memory | Depends on installed RAM |
| Disk | Should not stay at 100% constantly |
| Network | Depends on active downloads |
If one application constantly uses high CPU or memory, it may need to be restarted, updated, or removed.
Task Manager also lets you disable unnecessary startup applications that slow boot times.
4. Use Performance Monitor
Performance Monitor is one of Windows’ most powerful built-in diagnostic tools. Although it looks more advanced than other utilities, it provides detailed reports about system health.
To open it:
- Search Performance Monitor
- Open the application
- Expand Data Collector Sets
- Select System
- Run System Diagnostics
After a few minutes, Windows generates a report.
The report includes information about:
- Processor performance
- Disk usage
- Memory usage
- Device status
- Resource bottlenecks
- System warnings
If your computer has recurring slowdowns or unexplained crashes, this report often provides useful clues.
5. Check Storage Health
Low storage affects more than just available space.
If the main drive is close to capacity, Windows may struggle to manage updates and background processes efficiently, which can lead to slower performance.
To check storage:
- Open Settings
- Select System
- Choose Storage
Windows shows how your storage is being used.
You’ll see categories such as:
- Apps
- Temporary files
- Documents
- Pictures
- Videos
- System files
If storage is running low, delete unnecessary files or move large files to an external drive or cloud storage.
Enabling Storage Sense can also help Windows automatically remove temporary files.
6. Check Battery Health (Laptop Users)
Laptop batteries naturally lose capacity over time. Windows includes a built-in battery report that shows how much your battery has worn down since it was new.
- Open Command Prompt as Administrator.
- Run this command: powercfg /batteryreport
Windows creates an HTML report that you can open in your browser.
The report includes:
- Original battery capacity
- Current battery capacity
- Charge history
- Battery usage
- Estimated battery life
- Charging cycles
If your battery capacity has dropped significantly, shorter battery life is expected. This doesn’t necessarily mean your laptop is faulty. It simply indicates normal battery aging.
7. Keep Windows Updated
Many performance and security issues are fixed through Windows updates. That’s why checking for available updates should be a regular part of maintaining your PC.
Go to: Settings → Windows Update
Install:
- Security updates
- Driver updates
- Bug fixes
- Feature updates
Restart your computer after updates are installed.
Running an outdated version of Windows can lead to compatibility issues and security risks.
8. Scan for Malware
Malware can quietly slow your computer without showing obvious signs. Windows Defender, now known as Microsoft Defender Antivirus, provides built-in protection.
- Open Windows Security and select:
- Virus & threat protection
- Run either:
- Quick Scan
- Full Scan
A Full Scan takes longer but checks every file on your computer.
If threats are detected, Windows recommends appropriate actions to remove them safely.
9. Check Disk Errors
Hard drives and SSDs can develop file system errors over time.
Windows includes the Check Disk (CHKDSK) utility to identify and repair these issues.
- To use it, open Command Prompt as an administrator and run the following command: chkdsk C: /f
If Windows cannot scan immediately because the drive is in use, it will ask to schedule the scan during the next restart. When you run CHKDSK occasionally it helps detect storage problems in the system before they become more serious.
10. Watch System Temperature
Excessive heat can reduce performance and shorten hardware life.
If your laptop frequently becomes hot, slows down during heavy work, or unexpectedly shuts down, temperature may be the cause.
Windows doesn’t show detailed temperature readings for every component, so many users rely on trusted monitoring software for this purpose.
High temperatures can be caused by:
- Dust buildup
- Blocked air vents
- Faulty cooling fans
- Heavy background processes
Keeping your computer clean and ensuring proper airflow can greatly improve cooling.
Conclusion
Since you use your PC regularly, it is a must to learn how to check PC health in Windows, as it is one of the easiest ways to keep your computer running smoothly. Fortunately, Microsoft includes several tools that make the process simple, even for beginners.
The PC Health Check tool, Windows Security, Performance Monitor, Task Manager, and battery reports can help you identify problems before they become serious. Along with regular updates and routine maintenance, these tools can improve performance, extend the life of your hardware, and create a safer computing experience.
