A slow laptop wastes time and patience. Apps take forever to open, the browser freezes and even simple tasks lag. The good news is that many slowdowns come from fixable causes such as too many startup programs, full storage, outdated software or malware. This guide shares 15 proven ways to speed up a slow laptop on Windows and Mac, from free quick fixes to hardware upgrades.
Why laptops slow down
| Cause | Symptoms |
|---|---|
| Too many startup apps | Slow boot, laggy first minutes |
| Full storage | Sluggish performance, update failures |
| Too many browser tabs and extensions | High memory use, browser freezes |
| Outdated software or drivers | Bugs, slow performance |
| Malware or adware | Pop-ups, high CPU use |
| Overheating | Fans loud, performance drops |
| Old hard drive (HDD) | Slow boot and app loading |
| Not enough RAM | Freezing when multitasking |
| Battery saver mode | Reduced performance |
15 ways to speed up a slow laptop
1. Restart regularly
Restarting clears memory and finishes updates. Many people leave laptops asleep for weeks.
2. Disable startup apps
Windows: Open Task Manager (Ctrl + Shift + Esc), go to Startup apps and disable programs you do not need at boot.
Mac: Go to System Settings, General, Login Items and remove unnecessary items.
3. Uninstall unused programs and bloatware
Remove preinstalled trial software and apps you no longer use.
4. Free up storage
Keep at least 15 to 20 percent of your drive free. Use Storage Sense on Windows or Storage settings on Mac to remove temporary files and large unused files.
5. Limit browser tabs and extensions
Each tab and extension uses memory. Close unused tabs and remove extensions you do not need.
6. Update your operating system
Install the latest Windows or macOS updates for performance and security fixes.
7. Update drivers
On Windows, use Windows Update, Advanced options, Optional updates or the laptop maker’s support app for graphics and chipset drivers.
8. Scan for malware
Run a full scan with Microsoft Defender or your antivirus. See best free antivirus for Windows in 2027.
Frequently asked questions
Will a factory reset speed up my laptop?
Often yes, because it removes accumulated clutter, but back up first and try other fixes.
Does more RAM make a laptop faster?
If you often run out of memory, yes. If not, an SSD upgrade may help more.
9. Change power settings
Windows: Go to Settings, System, Power and battery and set Power mode to Best performance when plugged in.
Mac: Low Power Mode reduces performance; turn it off when you need speed.
10. Keep your laptop cool
Overheating forces the processor to slow down. Use the laptop on hard surfaces, clean vents with compressed air and consider a cooling pad.
11. Reduce visual effects
Windows: Search Adjust the appearance and performance of Windows and choose Adjust for best performance, or turn off specific animations.
Mac: In Accessibility, Display, enable Reduce motion and Reduce transparency.
12. Check what is using resources
Use Task Manager on Windows or Activity Monitor on Mac to find apps using high CPU, memory or disk. Close or uninstall heavy apps you do not need.
13. Turn off background sync when needed
Cloud storage apps syncing large files can slow performance. Pause syncing during heavy work.
14. Upgrade to an SSD
If your laptop still uses a hard disk drive, replacing it with a solid state drive is often the single biggest speed boost. Boot times can drop from minutes to seconds.
15. Add more RAM
If your laptop has upgradeable memory and you regularly use more than 80 percent of RAM, adding memory improves multitasking. Many modern thin laptops have soldered RAM, so check before buying.
How much RAM do you need?
| Use | Recommended RAM |
|---|---|
| Web browsing, email, documents | 8 GB |
| Heavy multitasking, many tabs | 16 GB |
| Photo editing, light video editing | 16 GB |
| Gaming, professional video, development | 16 to 32 GB |
Windows-specific tips
- Use Storage Sense to clean temporary files automatically
- Run Disk Cleanup for system files
- Check Windows Update for optional driver updates
- Use Startup apps in Task Manager to see startup impact
- Consider Reset this PC with keep my files if Windows is badly cluttered
Mac-specific tips

Real examples
The startup overload. Jake’s laptop took four minutes to boot. Twenty programs launched at startup. Disabling 15 cut boot time to under one minute.
The SSD upgrade. Maria’s six-year-old laptop felt unusable. Replacing the hard drive with an SSD made it feel faster than when she bought it.
The browser problem. Leo had 70 tabs and 15 extensions open. Using a tab manager and removing extensions freed several gigabytes of memory.
When to upgrade vs replace
| Situation | Recommendation | |
|---|---|---|
| Laptop under 4 years old, slow due to clutter | Clean up and optimize | |
| Has a hard drive (HDD) | Upgrade to SSD if possible | |
| Upgradeable RAM and frequent memory pressure | Add RAM | |
| Battery dies quickly | Replace battery; see [[243 | how to fix laptop battery draining fast]] |
| No longer receives OS or security updates | Consider replacing | |
| Hardware failures or physical damage | Compare repair cost with a new laptop | |
| Cannot run apps you need | Replace with a model that meets requirements |
A $50 to $100 SSD upgrade can extend a laptop’s life by years, which is far cheaper than a new computer.
Signs of hardware problems
- Clicking noises from the drive
- Frequent crashes or blue screens
- Very slow performance even after reset
- Fans running loudly constantly
- Battery swelling or trackpad lifting
If you notice these, back up immediately and consult a technician. Swollen batteries can be dangerous.
Quick 10-minute speed boost routine
- Restart the laptop.
- Close unnecessary tabs and apps.
- Disable two or three startup apps.
- Delete downloads and empty the trash or recycle bin.
- Run a quick malware scan.
- Check for updates.
Doing this monthly keeps your laptop running smoothly.
Frequently asked questions
Why is my new laptop slow?
Preinstalled bloatware, updates running in the background or low RAM may be to blame.
Do cleaner apps help?
Many third-party cleaners add little value or include adware. Built-in tools are usually enough.
Can too many fonts or desktop icons slow a laptop?
Slightly, but the impact is small compared with startup apps and storage.
Browser speed tips
Since most people spend the majority of their time in a browser, browser optimization makes a big difference:
| Tip | How | |
|---|---|---|
| Use memory saver features | Chrome Memory Saver and Edge Sleeping Tabs reduce memory for inactive tabs | |
| Remove extensions | Keep only essentials; see [[232 | best AI Chrome extensions for 2027]] for choosing carefully |
| Clear cache occasionally | Fixes some loading issues | |
| Update your browser | New versions include performance improvements | |
| Use bookmarks instead of open tabs | Save pages for later without using memory | |
| Disable autoplay | Fewer resources spent on videos and ads |
Clean up physically
Dust buildup inside vents and fans makes laptops run hot and slow. Every few months:
- Shut down and unplug the laptop.
- Use short bursts of compressed air into the vents.
- Wipe the keyboard and screen.
- Keep food and drinks away from the laptop.
For deep internal cleaning, consider a professional service, especially for laptops still under warranty.
Reset as a fresh start
If your laptop is still slow after all fixes, a reset can help:
- Windows: Settings, System, Recovery, Reset this PC, choose Keep my files or Remove everything
- Mac: Use Erase All Content and Settings on supported Macs, then reinstall apps
Back up everything first, including browser bookmarks and app license keys.
