10 Proven Ways to Speed Up a Slow Laptop Instantly

Is your laptop dragging its feet every time you try to open a browser tab or launch a program? Whether you're using a Windows PC or a MacBook, a slow laptop can ruin your productivity—and your mood.

The good news? You don't need to be a tech wizard to give your laptop a serious speed boost. With the right tweaks and a few minutes of your time, you can dramatically improve your laptop's performance.

In this guide, we'll cover 10 proven, beginner-friendly ways to speed up a slow laptop instantly—no expensive upgrades required.

1. Disable Startup Programs

When your laptop boots, dozens of background apps might be loading at the same time—eating up RAM before you even open a single program.

✅ How to Fix (Windows):

• Press Ctrl + Shift + Esc to open Task Manager

• Click on the Startup tab

• Right-click and disable unnecessary programs (e.g., Spotify, Zoom, OneDrive)

✅ How to Fix (Mac):

• Go to System Settings > General > Login Items

• Remove apps that you don’t need to start with macOS

Pro Tip: Less is more. Only keep security tools or essential productivity apps active on startup.

2. Uninstall Unused Applications

Old software you no longer use can still run background services or occupy valuable disk space. Removing them is one of the easiest ways to free up resources.

📌 What to Look For:

• Games you haven’t played in months

• Trial software you forgot to delete

• Manufacturer bloatware

On Windows: Use the “Add or Remove Programs” feature
On Mac: Simply drag the app to the Trash or use AppCleaner for a deeper uninstall

3. Clear Temporary Files and System Cache

Over time, your system accumulates temporary files, cached data, and logs that can clutter storage and slow performance.

🛠 Recommended Tools:

• Windows: Use the built-in Disk Cleanup or Storage Sense

• Mac: Use Finder > Go to Folder > ~/Library/Caches and delete non-essential folders

Alternatively, try third-party tools like:

• CCleaner (Windows/Mac)

• CleanMyMac X (Mac only)

Bonus Tip: Clear browser caches (Chrome, Safari, Edge) regularly—they can hog gigabytes of space.

4. Upgrade Your Browser or Switch to a Lightweight One

Your web browser could be a hidden resource hog, especially if you have dozens of tabs open.

⚡ What You Can Do:

• Update to the latest browser version

• Disable unnecessary extensions

• Consider switching to a lighter browser like Brave or Firefox Lite

Also: Use a tab suspension extension (like The Great Suspender) to freeze inactive tabs automatically.

5. Add More RAM (If Possible)

If your laptop struggles with multitasking or slows down when switching between apps, you may be running out of memory.

🔍 Check Your RAM Usage:

• Windows: Open Task Manager → Performance Tab

• Mac: Use Activity Monitor → Memory Tab

If your RAM is maxed out, consider upgrading:

• Most Windows laptops: RAM upgrade is simple and inexpensive

• MacBooks (2016+): RAM is soldered; consider virtual memory optimization instead

Even moving from 4GB to 8GB can make a night-and-day difference.

6. Switch from HDD to SSD (Solid State Drive)

If your laptop still uses a traditional hard drive, upgrading to an SSD is the single most effective performance boost you can give it.

🚀 Benefits of an SSD:

• Boot times drop from minutes to seconds

• Apps launch instantly

• File transfers are lightning-fast

Many laptops (especially older ones) support 2.5” SATA SSDs. Newer ones may support NVMe SSDs via M.2 slots.

Not sure if your laptop supports SSDs? Use tools like Crucial’s System Scanner to check compatibility.

7. Scan for Malware and Adware

Unwanted programs like adware, spyware, and malware can slow your laptop to a crawl and compromise your data.

🛡 Must-Have Tools:

• Windows Defender (built-in)

• Malwarebytes Anti-Malware (free/paid)

• Bitdefender or Kaspersky (lightweight antivirus)

Run a full scan and remove suspicious entries. Schedule weekly scans to stay protected.

8. Update Your Operating System and Drivers

Outdated OS versions or buggy drivers can slow down system processes or cause hardware to misbehave.

 What to Do:

• Windows: Go to Settings → Update & Security → Windows Update

• Mac: Go to System Settings → General → Software Update

Also, update your:

• Graphics drivers (NVIDIA, AMD, Intel)

• Audio and network drivers

You can use tools like Driver Booster (Windows) to automate the process.

9. Adjust Power Settings for Performance

Your laptop’s default power settings may prioritize energy saving, especially on battery—at the expense of speed.

🔌 Optimize Power Settings:

• Windows: Go to Control Panel → Power Options → High Performance

• Windows 11: Use Best Performance mode in the taskbar battery menu

• Mac: In Battery Settings, turn off “low power mode” when plugged in

Tip: Use performance mode when gaming, video editing, or multitasking heavily.

10. Reboot Regularly and Avoid Sleep Mode Overuse

Leaving your laptop in sleep mode for days without restarting can cause memory leaks, background process buildup, and lag.

🔄 Best Practices:

• Restart your laptop at least once every 2–3 days

• Shut it down overnight once or twice a week

• Avoid keeping too many browser tabs and apps open between sessions

A quick restart can flush RAM, close hidden background tasks, and refresh the OS.

Bonus: Use Lightweight Alternatives to Heavy Apps

Instead of using software that hogs resources, switch to streamlined alternatives:

Heavy App	Lightweight Alternative
Adobe Photoshop	Photopea or GIMP
Microsoft Word	Google Docs or Typora
Zoom	Google Meet (in-browser)
Chrome	Brave, Firefox Lite, or Edge
VLC Media Player	MPV Player
