If your computer feels slower than it used to, you’re not alone. Over time, unnecessary files, background apps, and system clutter can significantly reduce performance. The good news? You don’t need expensive software or expert help to fix it. By adjusting a few simple settings, you can dramatically boost your computer’s speed and responsiveness. Here are seven proven steps to make your computer run like new again.
1. Disable Startup Programs
Many applications automatically start when your computer boots up — even if you rarely use them. These background programs slow down startup time and consume valuable resources.
How to fix it:
-
Windows: Press
Ctrl + Shift + Esc→ Go to Startup tab → Disable unnecessary programs. -
macOS: Go to System Settings > General > Login Items → Remove apps you don’t need.
This small change can noticeably speed up your computer’s startup process.
2. Uninstall Unused Software
Old or unused programs not only take up storage space but can also run hidden services in the background. Cleaning them out can free up system resources.
Steps:
-
Go to Control Panel > Programs > Uninstall a program (Windows).
-
On macOS, drag unwanted apps from the Applications folder to Trash.
-
Restart your computer afterward.
3. Clean Temporary Files and Cache
Temporary files accumulate every time you browse the internet, install programs, or perform updates. Deleting them regularly can improve performance and free up gigabytes of storage.
Recommended methods:
-
Windows: Use Disk Cleanup or Storage Sense.
-
macOS: Use Manage Storage under About This Mac > Storage.
You can also use built-in tools to clear browser caches and system logs safely.
4. Adjust Power Settings for Performance
Your computer’s default power mode might prioritize energy saving over speed. Changing it to a high-performance plan can increase system responsiveness.
Windows:
-
Go to Control Panel > Power Options.
-
Select High Performance.
macOS:
-
Go to System Settings > Battery.
-
Adjust settings to favor performance over energy efficiency.
5. Update Your System and Drivers
Outdated operating systems and drivers can slow down performance and cause compatibility issues. Regular updates ensure smoother operation and better security.
To update:
-
Windows: Go to Settings > Windows Update.
-
macOS: Go to System Settings > Software Update.
-
Also, update drivers for graphics, storage, and network devices through official manufacturer websites.
6. Manage Background Processes
Even after startup, many apps keep running in the background — consuming CPU, RAM, and battery life.
Quick fix:
-
Open Task Manager (Windows) or Activity Monitor (macOS).
-
Identify processes that use high CPU or memory.
-
End unnecessary ones — but be careful not to stop essential system tasks.
This can instantly make your computer feel faster, especially when multitasking.
7. Optimize Storage with an SSD
If you’re still using a traditional hard drive, switching to a Solid-State Drive (SSD) can be the single biggest performance boost. SSDs load files, applications, and the operating system much faster.
Performance Comparison:
| Feature | HDD | SSD |
|---|---|---|
| Boot Time | 30–60 seconds | 10–15 seconds |
| File Loading | Slower | Much faster |
| Noise | Audible spinning | Silent |
| Durability | Prone to damage | Shock-resistant |
Although SSDs cost a bit more, the speed improvement is well worth the investment.
Bonus Tip: Keep Your System Organized
Regularly declutter your desktop, remove duplicate files, and keep software updated. Also, schedule a monthly cleanup routine to maintain top performance.
Making your computer run faster doesn’t always require new hardware or costly programs. By applying these seven simple settings — from disabling startup apps to optimizing storage — you can restore speed, reduce lag, and extend your device’s lifespan. With just a few tweaks, your computer can feel almost brand new again.
