Discover practical tips to improve performance, free up storage, and keep your PC running smoothly.

Why Computers Slow Down

Multiple factors contribute to declining performance:

• Too many startup programs
• Low available storage
• Outdated Windows or drivers
• Malware or unwanted software
• Fragmented hard drives (HDD only)
• Too many browser extensions
• Insufficient RAM for challenging tasks
• Dust causing overheating and thermal throttling.

The good news is that many of these issues can be fixed at little or no cost.

1. Make it a habit to restart your computer regularly.

Many users leave their computers on for days or even weeks; restarting clears temporary memory, stops unnecessary background processes, and lets Windows install queued updates.

If you use your computer regularly, restart it at least once every few days.

2. Switch off any startup programs that are not needed

When Windows starts, many applications launch automatically, increasing boot time and consuming system resources.

How to turn off startup apps

1. Open Task Manager by pressing Ctrl+Shift+Esc.

2. Switch to the Startup Apps tab.

3. At startup, turn off any programs you don't need.

Disable rarely used software rather than turning

 off essential security or hardware utilities.

3. Free Up Disk Space

When your system drive is almost full, Windows usually slows down, and you may notice your computer running more slowly.

Delete:

• Temporary files
• Old downloads
• Duplicate files
• Unused applications
• Large videos you no longer need

You can set up Windows Storage Sense to automatically delete files you don’t need.

4. Remove programs that you no longer use

Unused apps take up space and may keep running in the background, using up your computer’s resources.

To uninstall:

• Open Settings
• Go to Apps
• Select Installed Apps
• Remove software you no longer need

Be careful not to remove drivers or important programs if you’re not sure what they do.

5. Update Windows

Microsoft often releases updates that make your computer faster, safer, and more reliable.

To check for updates:

Go to Settings, choose Windows Update, and check for updates.

Install updates as soon as they’re available, and restart your computer to finish the process.

6. Scan for Malware

Malware and unwanted software can significantly slow down your computer.

Windows comes with Microsoft Defender, which protects most users well. For extra security, you can use another trusted anti-malware program. Running antivirus scans regularly helps find and remove software that slows down your computer.

7. Limit Browser Extensions

Every browser extension uses some of your computer’s memory and processing power.

Go to your browser’s extensions page and remove any extensions you don’t need anymore.

Keeping only the extensions you really need can improve browser performance and help prevent problems.

8. Upgrade to an SSD.

If your computer still uses a regular hard drive (HDD), switching to a solid-state drive (SSD) is one of the best ways to make it faster.

Benefits include:

• Faster startup
• Quicker application launches
• Improved file transfers
• More responsive multitasking

Even older computers usually get much faster after you install an SSD.

9. Increase the amount of RAM if necessary.

Adding more RAM can help if your computer struggles to run several programs at once.

Typical suggestions:

• 4 GB RAM: Basic browsing and light tasks
• 8 GB RAM: Everyday work, study, and entertainment
• 16 GB RAM: Multiple multitasking, creative software, and gaming

Before buying more memory, check that your computer supports it and find out what type you need.

10. How to clean the dust out of your computer

Dust buildup can block airflow, which can make your computer overheat and slow down.

Regularly:

• Clean air vents
• Clean the cooling fans of dust.
• Make sure there’s enough space around your computer for airflow. If you can’t open your computer to clean inside, ask a professional for help. Also, keep your desktop tidy, since too many files and shortcuts can make things harder to find and slow your computer.

Create folders for:

• Work
• School
• Photos
• Downloads
• Personal documents

A tidy desktop can help you get more done.

12. Use the built-in performance tools.

Windows has built-in tools to help keep your computer running well:

• Storage Sense can delete temporary files.
• Disk Cleanup frees up disk space.
• Task Manager can identify applications that use a lot of resources.
• If you want to track your computer’s performance in detail, try using Performance Monitor.
• This tool lets you defragment hard drives and optimize solid-state drives.

Computers & Software

Frequently Asked Questions

Will deleting temporary files make my computer faster?

Yes, temporary files take up storage space and can slow performance over time, so it's a good idea to remove them occasionally so Windows can run more smoothly.

Should it be worthwhile to upgrade an old laptop?

In many cases, yes. Replacing the HDD with an SSD and adding more RAM can significantly improve performance and extend the device's life.

Is it advisable to use PC cleaning software?

Effective maintenance tools are built into Windows. When using third-party utilities, install them only from reputable developers and avoid any programs that make unrealistic performance claims.

Final Thoughts

Just because a computer is slow doesn't mean it's time to buy a new one. You can often improve its performance considerably through regular maintenance, wise storage management, keeping the system up to date, and—if your hardware permits it—by installing an SSD or more RAM.

If you follow the tips in this guide, you'll not only save money but also have a faster, more responsive Windows experience.
