Your laptop didn’t get slower overnight—you just gradually added more apps, background tasks, and clutter until performance started to drag. The good news is you usually don’t need a new machine to get a big boost. With a few focused changes, you can improve laptop speed, shorten boot times, and make everyday tasks feel snappy again. This guide walks through nine practical fixes you can apply today, whether you’re on Windows or macOS. You’ll learn how to reduce startup bloat, free up storage, tame heavy browser habits, and check for hidden bottlenecks like overheating or failing drives. Pick the steps that match your symptoms, work through them in order, and you’ll feel the difference fast.
1) Clear the clutter: storage, temporary files, and “too many tabs”
When storage gets tight or your system is constantly chewing through caches, it has less room to breathe. Cleaning house is one of the quickest wins for laptop speed, especially on older machines.
Use built-in cleanup tools (Windows + macOS)
Start with the tools your laptop already has. They’re safe, quick, and designed not to break anything important.
On Windows:
1. Open Settings → System → Storage.
2. Turn on Storage Sense (or run it manually).
3. Review “Temporary files” and remove what you don’t need (old update files can be huge).
On macOS:
1. Go to System Settings → General → Storage.
2. Review recommendations like “Optimize Storage,” “Empty Trash Automatically,” and “Reduce Clutter.”
3. Remove large unused installers, old iPhone backups, and duplicate downloads.
A good rule of thumb:
– Keep at least 15–20% of your drive free for smooth performance.
– If you’re under 10% free space, sluggishness is common.
Trim browser load and extension bloat
Many people blame the computer when the real culprit is the browser. Modern web apps can consume gigabytes of memory, and extensions add constant background activity.
Do this in any browser:
– Close tabs you truly don’t need (or bookmark them).
– Remove extensions you haven’t used in 30 days.
– Disable “run in background” if you don’t need notifications when the browser is closed.
– Clear cached images/files if pages load oddly or slowly.
Example: If your laptop feels slow “only when Chrome is open,” check the browser’s task manager (Chrome: More tools → Task Manager) to see which tab or extension is hogging resources. Cutting one rogue extension can noticeably improve laptop speed in minutes.
2) Cut startup and background tasks for instant laptop speed gains
A laptop can have great hardware and still feel slow if dozens of programs launch at startup or keep running in the background. This is one of the most common causes of “it used to be fast.”
Disable unnecessary startup items
On Windows:
1. Press Ctrl + Shift + Esc to open Task Manager.
2. Go to Startup apps.
3. Disable anything you don’t need immediately (chat updaters, game launchers, vendor utilities, etc.).
On macOS:
1. System Settings → General → Login Items.
2. Remove items you don’t want opening at sign-in.
3. Check “Allow in the Background” and turn off anything non-essential.
What to keep on startup:
– Security software (if you use one beyond built-in protection)
– Touchpad/keyboard utilities if required for function keys
– Cloud sync tools you rely on (but consider pausing them while working)
What to question:
– “Helper” apps, auto-updaters, and preinstalled trialware
– Multiple chat apps launching together
– Anything you don’t recognize (research it before removing)
Stop resource-heavy background sync when you need performance
Cloud tools are useful, but they can crush responsiveness during big uploads or indexing.
If your laptop is slow during work sessions:
– Pause OneDrive/Dropbox/Google Drive sync temporarily.
– Schedule large photo/video backups overnight.
– On macOS, give Spotlight indexing time to finish after big file moves.
Tip: If the laptop becomes sluggish only when plugged in at a desk, it might be syncing, updating, or backing up in the background. Pausing those jobs can restore laptop speed immediately.
3) Update wisely: OS patches, drivers, and app housekeeping
Updates can improve performance and stability, but they can also pile up, conflict, or run constantly if neglected. A clean update routine keeps your system predictable.
Apply OS updates and key app updates
OS updates often include performance improvements and bug fixes. Keep them current, but don’t update during a critical deadline.
On Windows:
– Settings → Windows Update → Check for updates
– Install optional updates carefully (especially driver updates) only if needed
On macOS:
– System Settings → General → Software Update
Also update:
– Browser
– Video conferencing apps
– GPU drivers (especially for creative work or light gaming)

Refresh or remove “problem apps”
If one app consistently freezes, crashes, or eats CPU, treat it like a performance leak.
Try this sequence:
1. Update the app.
2. Reset the app’s cache/settings (many apps offer a “reset” or “repair”).
3. Uninstall and reinstall.
4. Replace it with a lighter alternative if needed.
Example: If your laptop struggles on startup and you have three different “PC optimizer” tools installed, remove them. Many so-called optimizers run constant background tasks and create the slowdown they claim to fix.
4) Optimize settings that quietly throttle performance
Sometimes the issue isn’t “junk” at all—it’s a setting that limits performance to save battery, reduce heat, or prioritize quiet operation. Adjusting these can restore laptop speed without buying anything.
Check power mode and battery health
On Windows:
– Settings → System → Power & battery
– Set Power mode to “Best performance” when plugged in (use “Balanced” on battery)
On macOS:
– System Settings → Battery
– Look for Low Power Mode (great for battery, not great for performance)
Battery health matters too. A degraded battery can cause power management quirks on some laptops, including unexpected throttling. If your battery life has dropped dramatically and performance is inconsistent, a battery replacement can be a real speed fix.
Reduce visual effects (especially on older systems)
Visual effects look nice but can feel heavy on older hardware.
On Windows:
1. Search “Performance Options.”
2. Choose “Adjust for best performance” (or customize and keep only what you like).
On macOS:
– Reduce Motion and Reduce Transparency (System Settings → Accessibility → Display)
This won’t turn an old laptop into a gaming rig, but it can make the interface feel more responsive—faster window animations, smoother switching, fewer stutters.
5) Hardware and heat: the hidden enemies of laptop speed
If your laptop fan is loud, the bottom feels hot, or performance drops after 10–20 minutes, you may be thermal throttling. Heat forces the CPU (and sometimes GPU) to slow down to prevent damage. Fixing airflow issues can dramatically improve laptop speed under load.
Stop overheating with simple maintenance
Start with the basics:
– Use the laptop on a hard surface (not a bed, couch, or blanket).
– Clean dust from vents using short bursts of compressed air.
– Keep the rear/side vents unobstructed.
– Consider a laptop stand to improve airflow.
Signs heat is the problem:
– Sudden slowdowns during video calls or while charging
– Fan spins loudly even when doing simple tasks
– Performance improves briefly after a restart, then degrades again
If you’re comfortable (and your warranty allows), a deeper clean and fresh thermal paste can help older machines. If not, a local repair shop can often do this affordably.
Know when an upgrade is worth it (SSD and RAM)
Two upgrades consistently deliver the biggest real-world improvements:
1. Move from HDD to SSD (if your laptop still has an old spinning drive)
– Faster boot times
– Faster app launches
– Less stuttering when multitasking
2. Add RAM (if you’re constantly maxing memory)
– Better multitasking
– Fewer slowdowns with many browser tabs
– Smoother work in spreadsheets, photo editors, and meeting apps
Quick guidance:
– 8 GB RAM is workable for light use, but 16 GB is a sweet spot for most people today.
– Any SSD is a big step up from an HDD; NVMe SSDs are even faster if supported.
If you’re unsure what’s inside your laptop, check:
– Windows: Task Manager → Performance tab (Disk type, Memory)
– macOS: About This Mac → More Info → System Report
6) Safety checks and “reset” options when nothing else works
If you’ve tried the practical fixes and your laptop still crawls, it’s time to rule out malware, failing hardware, or a corrupted OS install. This section contains the “last mile” speed fixes that often restore a machine to like-new behavior.
Run a malware and adware sweep
Malware isn’t always dramatic pop-ups. Sometimes it’s quiet background activity that steals CPU, network bandwidth, and disk performance.
Good practices:
– Use your built-in security tools first (Windows Security on Windows; XProtect on macOS plus safe browsing habits).
– Remove suspicious browser extensions.
– Be cautious with “free” download sites and cracked software.
Red flags:
– Browser homepage/search engine changing without permission
– Constant CPU usage even when idle
– Random new toolbars/extensions installed
– Fans running hard while you’re doing nothing
If you suspect infection, scan, remove, then change important passwords (starting with email). That alone can bring laptop speed back to normal if a background miner or adware was the cause.
Use repair, refresh, or reinstall as a clean finish
When performance issues are persistent and hard to diagnose, a clean system refresh can be the most time-efficient fix.
On Windows:
– Consider “Reset this PC” (Settings → System → Recovery).
– Choose to keep files if you want, but note: a full clean install usually performs best.
– Back up files first.
On macOS:
– Back up with Time Machine (or your preferred method).
– Consider reinstalling macOS from Recovery if the system feels corrupted.
Before you reset:
– List your essential apps and license keys.
– Save browser bookmarks and password manager access.
– Export critical settings (email, VPN profiles, etc.).
Many users report the biggest laptop speed improvement after a clean reinstall—because it eliminates years of accumulated startup items, drivers, and background services in one sweep.
Key takeaways: Your fastest wins come from freeing storage, reducing startup apps, and taming browser load. If performance drops under heat, improve airflow and clean vents; if your laptop still uses an HDD, an SSD upgrade is often transformative. Keep updates under control, scan for malware if things feel “off,” and consider a reset when troubleshooting becomes a time sink.
