Your laptop doesn’t have to feel “old” just because it’s a few years (or even a few months) into daily use. Most slowdowns come from fixable clutter: too many apps running at startup, a stuffed storage drive, outdated software, or a browser that’s quietly hoarding tabs and extensions. The good news is that you can often restore that snappy, just-unboxed feel without buying new hardware. In this guide, you’ll walk through nine practical speed fixes that work for Windows and macOS, with clear steps and checkpoints so you can see progress as you go. Tackle them in order for the biggest impact, or jump straight to the ones that match your symptoms—either way, these speed fixes can make a noticeable difference today.
1) Diagnose the slowdown first (so you pick the right speed fixes)
Guessing wastes time. A quick diagnosis tells you whether you’re fighting a CPU bottleneck, low memory, a nearly full drive, or background software.
Run quick performance checks (Windows + macOS)
On Windows:
1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click Processes and sort by CPU, Memory, and Disk.
3. Watch for anything pinned near the top for more than a minute or two.
On macOS:
1. Open Activity Monitor (Spotlight search: “Activity Monitor”).
2. Check CPU and Memory tabs.
3. Look for apps using unusually high CPU or showing “Memory Pressure” in yellow/red.
What you’re looking for:
– CPU consistently above ~70–80% when you’re not doing heavy work
– Memory nearly full (Windows “Memory” high usage; macOS “Memory Pressure” warning)
– Disk usage stuck near 100% (Windows) or frequent beachballing (macOS)
Know the common “slow laptop” culprits
Most sluggish laptops trace back to a few patterns:
– Too many startup programs and background utilities
– Low free storage (especially on SSDs that need breathing room)
– Browser bloat (extensions, cached junk, too many tabs)
– OS updates pending or drivers out of date (Windows especially)
– Thermal throttling from dust and heat
– Malware or adware (more common than people think)
Once you know the likely cause, the speed fixes below become much faster to apply—and more effective.
2) Clean up startup and background apps (high-impact speed fixes)
If your laptop takes forever to boot or feels heavy right after logging in, startup items are often the reason.
Disable unnecessary startup programs
Windows:
1. Open Task Manager → Startup apps (or “Startup” tab depending on version).
2. Disable anything you don’t need immediately at boot (chat apps, game launchers, updaters you don’t rely on).
macOS:
1. System Settings → General → Login Items.
2. Remove or disable apps you don’t need launching automatically.
Good candidates to disable:
– Meeting apps you only use occasionally
– Music streaming apps
– Non-essential “helper” tools
– Old cloud sync tools you no longer use
Keep enabled:
– Security software you trust
– Trackpad/keyboard utilities you actively need
– Cloud sync tools you use daily (but consider “pause sync” during heavy work)
Stop background hogs safely
Instead of force-quitting randomly, focus on repeat offenders you recognize:
– If a cloud sync tool is re-indexing, let it finish or pause it temporarily.
– If an app updater is stuck, uninstall the app or reinstall cleanly.
Tip: After you disable startup items, reboot once. Many speed fixes don’t “show up” until a clean restart.
3) Free storage and reduce disk strain (speed fixes that feel immediate)
Storage affects everything: boot time, app launches, updates, and multitasking. When the drive is too full, performance drops—especially on systems doing lots of background indexing.
Hit your free-space targets
Aim for:
– SSD: keep at least 15–20% free
– HDD: keep at least 10–15% free (and consider defragmentation if it’s truly an HDD)
Quick wins to delete or move:
– Old installers and .zip files in Downloads
– Duplicate photos/videos
– Unused games and large apps
– Offline movies you’re done with
Windows built-ins:
– Settings → System → Storage → Temporary files
– Storage Sense (turn it on to automate cleanup)
macOS built-ins:
– System Settings → General → Storage → Recommendations (Review Files, Reduce Clutter)
Move big files the smart way
If you’re always near full:
– Move archives to an external SSD or a reliable cloud drive
– Store media libraries externally (Photos, video projects, raw footage)
– For creators: keep active project files on the internal drive, archive old projects off-device
Example: If your internal SSD is 256GB and you keep only 30GB free, freeing even 50–80GB can noticeably reduce lag during updates and app launches.

4) Optimize the browser (often the biggest “hidden” speed fix)
Many “slow laptop” complaints are actually “slow browser” problems. Browsers can consume huge memory, run multiple background processes, and keep extensions active even when you’re not paying attention.
Trim extensions, tabs, and cached data
Do this once a month:
– Remove extensions you don’t actively use
– Disable “shopping helpers” and coupon extensions if you notice lag
– Close tab piles and use bookmarks or a read-later tool instead
– Clear site data/cache if pages load oddly or feel sluggish
Practical rule:
– If an extension hasn’t earned its keep in 2 weeks, remove it.
Use built-in performance tools
Chrome/Edge:
– Open Settings → Performance (or search “performance” in settings)
– Enable features like “Memory Saver” (naming varies by browser version)
Firefox:
– Settings → Performance
– Consider unchecking “Use recommended performance settings” to adjust manually if needed
These speed fixes are especially noticeable on laptops with 8GB RAM or less.
5) Update the OS, drivers, and apps (speed fixes that also prevent crashes)
Updates aren’t just new features. They often include performance improvements, stability fixes, and security patches.
Prioritize the right updates
Windows:
– Run Windows Update
– Update graphics drivers (Intel/AMD/NVIDIA) if you see stutter, screen flicker, or poor performance
– Update Wi-Fi and chipset drivers if you have random slowdowns or disconnects
macOS:
– Update macOS via System Settings → General → Software Update
– Update App Store apps and any major tools you rely on (browser, office apps, creative tools)
If you’re nervous about updates:
– Back up first
– Install one “chunk” (OS updates first, then drivers) so it’s easier to troubleshoot if anything changes
Remove or replace problem software
If one app constantly spikes CPU or memory, consider:
– Reinstalling it cleanly
– Switching to a lighter alternative
– Turning off “launch on startup” and “run in background”
Sometimes the best speed fix is simply deleting the app you don’t actually need.
6) Reduce heat and power throttling (speed fixes for laptops that slow down over time)
If your laptop starts fast, then gets sluggish after 15–30 minutes, heat is a likely culprit. When temperatures rise, the CPU may throttle to protect itself, causing sudden performance drops.
Basic cooling improvements anyone can do
Start with these:
– Use the laptop on a hard surface (not a blanket or couch)
– Elevate the rear slightly for airflow
– Clean vents gently with compressed air (short bursts, from a safe distance)
Signs you’re dealing with heat:
– Fan noise ramps up quickly
– Keyboard area feels hot to the touch
– Performance drops during video calls, gaming, or many browser tabs
Choose the right power mode
Windows:
– Settings → System → Power & battery → Power mode
– If you need speed while plugged in, choose “Best performance” (wording varies)
macOS:
– System Settings → Battery
– Check Low Power Mode (turn it off when you need maximum performance)
– On Apple Silicon Macs, Low Power Mode can significantly reduce peak performance
Power settings are underrated speed fixes because they’re easy, reversible, and immediately testable.
7) Scan for malware and remove adware (essential speed fixes when “everything feels off”)
If you notice pop-ups, suspicious toolbars, or your browser homepage changed, treat it as a performance and security issue.
Use reputable built-in tools first
Windows:
– Windows Security → Virus & threat protection → Full scan
– Consider an Offline scan for stubborn threats
macOS:
– While macOS has strong built-in protections, adware can still sneak in via shady installers
– Remove unknown browser profiles, extensions, and “helper” apps you don’t recognize
Red flags:
– Fans running high when you’re doing nothing
– New apps you didn’t install
– Browser redirects or constant new tabs
Clean out “potentially unwanted programs”
These aren’t always “viruses,” but they drain resources:
– Bundled download managers
– Fake “system cleaner” apps
– Browser toolbars and coupon injectors
If you uninstall something and your laptop suddenly feels lighter, that’s one of the most satisfying speed fixes you’ll ever do.
8) Repair, reset, or reinstall (the most powerful speed fixes when cleanup isn’t enough)
Sometimes performance problems are deeply baked into the system: corrupted caches, years of accumulated settings, or misbehaving services.
Try targeted repairs before a full reset
Windows helpful commands (use carefully):
– Built-in Disk Cleanup and Storage tools first
– If system files seem corrupt, Windows has repair utilities (SFC/DISM). If you’re not comfortable, ask a pro or follow Microsoft’s official guidance.
macOS:
– Boot in Safe Mode to test whether the slowdown is caused by login items or extensions
– Use Disk Utility to check the drive
When a reset is the smartest move
Consider resetting/reinstalling if:
– Boot time has doubled over the years
– Random freezes persist after all other speed fixes
– You’ve migrated data across multiple laptops/OS versions and weird bugs follow you
Before you reset:
– Back up everything (cloud + external drive if possible)
– Export browser bookmarks and password manager data
– List critical apps/licenses
A clean install can feel like a brand-new machine—especially on older hardware.
9) Upgrade hardware strategically (only if it’s worth it)
If you’ve done the software work and your laptop is still slow, a small hardware upgrade can deliver a big jump—assuming your model supports it.
Best upgrades for most laptops
– Move from HDD to SSD (massive improvement if you’re still on a hard drive)
– Upgrade RAM (especially if you have 8GB and multitask heavily)
– Replace an aging battery if the system throttles on battery power or shuts down unexpectedly
Simple guidance:
– If your laptop has an HDD, switching to an SSD is often the #1 performance upgrade.
– If your laptop already has an SSD but struggles with multitasking, RAM is usually next.
Know when not to upgrade
Skip upgrades if:
– The laptop has soldered RAM and a tiny SSD that’s not replaceable
– The CPU is too old for your workload (e.g., heavy editing, modern games)
– Repair/upgrade costs approach the price of a newer, more efficient machine
In those cases, focus on the earlier speed fixes and plan a smarter replacement timeline.
You don’t need to do all nine changes at once to feel improvement. Start with the highest-impact speed fixes: disable startup bloat, free up storage, and slim down your browser. Then layer in updates, cooling tweaks, and a malware scan if anything feels suspicious. If performance still doesn’t match what you need, a reset or a targeted hardware upgrade can be the final step that makes your laptop feel genuinely new again.
