Have you ever felt like your PC isn’t performing well lately? Maybe it’s slower than before, freezes more often, or even makes you wonder, “Is it broken?”

That’s when you should try running a PC “health check”!

This method will scan your system software for problems and automatically repair them if needed. Think of it like a medical check-up for your PC, helping it stay “healthy.” Let’s get started!

1. What Does This Health Check Do?

This time, we’ll be checking your PC’s software—its core system, Windows.

• Apps crash or run unstable
• Startup takes too long
• Updates fail frequently

Many of these issues are often caused by corrupted system files. This health check finds and repairs the root of such problems.

💡 Next time, we’ll cover how to check the hardware health of your PC!

2. Why Is a Health Check Necessary?

Windows updates frequently rewrite internal files. But sometimes updates fail, or system files get corrupted.

If left unchecked, you could face:

• Apps crashing suddenly
• The dreaded blue screen
• A PC that won’t boot

That’s why it’s so important to regularly check your system and repair errors before they cause bigger issues.

3. Prepare Before Running the Health Check

Before starting, make sure of the following:

1. Check Internet Connection

   • Some repairs may need to download files.

2. Temporarily Disable Security Software (Optional)

   • It may interfere with the process. Remember to re-enable it afterwards.

3. Allow Enough Time

   • The scan may take a while—running it before bed is a good idea.

4. Create a Restore Point (Very Important!)

   • Lets you roll back in case something goes wrong.

How to Create a Restore Point

1. Type “Restore” in the Windows search bar
2. Click “Create a restore point”
3. Make sure System Protection is enabled
4. Click Create, give it a clear name, and save!

4. Running the Health Check (DISM & SFC)

Now for the main part! We’ll use Windows’ built-in repair tools DISM and SFC to scan and fix your system.

Step 1: Open Command Prompt

1. In the Start menu, type “Command”
2. Right-click Command Prompt → select Run as Administrator

⚠️ Important: Simply opening it normally won’t allow repairs.

Step 2: Repair System with DISM

Copy and paste this command into the black window using Ctrl + V:

DISM /Online /Cleanup-Image /RestoreHealth

Press Enter to run it.

Step 3: Scan Files with SFC

Once DISM finishes, run this command:

sfc /scannow

Paste it, press Enter, and let it run.

5. Key Points & Precautions

• Always run in this order: DISM → SFC (Microsoft’s official recommendation)

• Don’t give up after one try Sometimes repeating the DISM + SFC combo 2–3 times clears stubborn errors.

6. What If Errors Can’t Be Fixed?

If you see error messages, don’t panic—there are solutions.

🔍 Searching terms like “Command Prompt repair not working” will bring up many detailed solutions.

Conclusion: Reset PC Issues Early with a Health Check

The DISM and SFC health check is a powerful way to fix PC troubles yourself.

• A great first step if Windows feels slow or unstable
• Running it regularly helps prevent future problems
• Even error messages aren’t scary if you know the fixes!

With this check-up, your PC may feel refreshed and run smoothly again. Next time, we’ll show you how to check your PC’s hardware health. Stay tuned!
