How to Speed Up a Slow Laptop: 10 Proven Fixes for Windows and Mac
If your laptop takes forever to start, lags when you open a browser, or freezes during simple tasks, you are not alone — and you probably do not need a new computer yet. Learning how to speed up a slow laptop usually comes down to a handful of fixes that cost little or nothing: clearing out startup programs, freeing storage space, updating software, and removing the clutter that builds up over months of everyday use. This guide walks through ten proven fixes that work on both Windows and Mac, in order from the easiest wins to the bigger upgrades, so you can work through them one at a time and stop as soon as your laptop feels fast enough.
Before you change anything, it helps to know what “slow” actually means for your machine. A laptop can feel slow for very different reasons: it may be short on free storage, running too many programs at once, overheating because its vents are clogged with dust, or simply carrying years of accumulated apps and files. The fixes below address each of these causes, and most of them take less than ten minutes.
1. Restart Your Laptop Properly
It sounds too simple to matter, but a real restart is the first step in how to speed up a slow laptop, because it clears temporary memory, ends stuck background processes, and lets pending updates finish installing. Many people close the lid and put their laptop to sleep for weeks at a time, which means small problems pile up in the background. Shut the machine down completely, wait a few seconds, and turn it back on. If it feels noticeably faster afterwards, make a full restart part of your weekly routine. On Windows, use Start, then Power, then Restart, rather than just closing the lid. On a Mac, use the Apple menu and choose Restart.
2. Stop Unnecessary Startup Programs
One of the biggest reasons a laptop crawls after booting is that dozens of programs launch themselves at startup. Chat apps, cloud storage tools, music players, and updaters all compete for attention the moment you log in, and each one slows everything else down. On Windows, open Task Manager, go to the Startup apps tab, and disable anything you do not need immediately when the computer turns on. Disabling a startup program does not uninstall it — it simply waits until you open it yourself. On a Mac, open System Settings, go to General, then Login Items, and remove the apps you do not need at login. Keep your security software and cloud sync tools if you rely on them, but be honest about the rest: if you have not opened an app in a month, it does not need to start with your computer.
3. Free Up Storage Space
A nearly full drive is one of the most common causes of a sluggish laptop. When storage drops below roughly 10 to 15 percent free space, the operating system struggles to create temporary files and manage virtual memory, and everything slows down. Start by checking how much space you have left, then delete what you do not need: old downloads, duplicate photos, installers you already ran, and large videos you have already backed up. Empty the Recycle Bin or Trash afterwards, because deleted files still take up space until you do. Both Windows and macOS have built-in storage tools that show which categories are using the most room, so check those first and target the biggest folders. If you create a lot of media, our guide to the best video editing software can help you pick tools that work well even on modest hardware — but no software runs well on a drive that is completely full.
4. Uninstall Apps You No Longer Use
Over time, laptops collect programs that were installed for one project and then forgotten. Each one takes up storage, and some keep background services running even when you never open them. Go through your installed apps list once every few months and remove anything you do not recognise or no longer use. On Windows, this is under Settings, then Apps, then Installed apps. On a Mac, open the Applications folder and drag unused apps to the Trash, then empty it. Be careful with anything you do not recognise that sounds like a system component — when in doubt, search the name first rather than removing it. The goal is to remove the trial software, old games, and duplicate utilities, not the drivers and helpers your system needs.
5. Update Your Operating System and Drivers
Updates are easy to postpone, but they often include performance improvements, bug fixes, and security patches that keep a laptop running smoothly. Check for operating system updates on Windows through Settings and Windows Update, and on a Mac through System Settings and Software Update. While you are there, update your main apps and browser too, since an out-of-date browser with old extensions can feel far slower than the laptop itself. Graphics and storage drivers matter as well; on Windows, check your laptop maker’s support page for driver updates if you notice display or performance problems after a major update.
6. Check What Is Using Your Resources
When a laptop suddenly slows down, one program is often hogging the processor or memory. On Windows, Task Manager shows CPU, memory, and disk usage per app — sort by the busiest column and look for anything using far more than it should. A browser with dozens of open tabs is a frequent culprit, as is a cloud backup running its first big sync. On a Mac, Activity Monitor does the same job. If you find a runaway process, close the app normally first; force-quitting should be a last resort, since it can lose unsaved work. If the same app misbehaves repeatedly, updating or reinstalling it often fixes the problem. Learning how to speed up a slow laptop is partly about building this habit: when things feel slow, look at what is actually running before assuming the hardware is at fault.
7. Tame Your Browser Tabs and Extensions
For many people, the browser is the slowest part of the laptop, and the laptop itself is fine. Each open tab uses memory, and each extension adds its own overhead. If you routinely keep thirty or forty tabs open, try bookmarking pages you want to keep and closing the rest — or use your browser’s tab groups and sleeping-tabs features, which park inactive tabs and free up memory. Review your extensions too: remove any you do not use, and keep only the ones that genuinely help you every week. Clearing your browser cache occasionally can also help, though it means some sites will load a little slower the first time you visit them again. Small habits here add up to a noticeably faster-feeling machine.
8. Scan for Malware and Unwanted Software
Malware and unwanted programs can quietly consume processor time, show extra ads, and slow a laptop to a crawl. Run a full scan with your built-in protection — Windows Security on Windows, or a reputable scanner on a Mac — and remove anything it flags. Also look out for programs you did not install yourself, browser toolbars you do not remember adding, and new home pages you did not choose. These are signs of bundled software that arrived with a free download. Removing them is often one of the fastest ways to restore a laptop’s speed, and it improves security at the same time.
9. Clean the Dust and Keep the Laptop Cool
Laptops slow themselves down on purpose when they overheat, a safety feature called thermal throttling. If your fan runs loudly all the time or the base feels hot during light work, dust may be blocking the vents. With the laptop off and unplugged, use short bursts of compressed air to clear the vents, holding the can upright and keeping the nozzle a few inches away. Make sure the vents are not blocked by soft surfaces: using a laptop on a bed or a cushion traps heat, while a hard, flat surface lets air flow. If the fan noise never stops even after cleaning, a failing fan or dried-out thermal paste may be the cause, and that is a job for a repair shop rather than a do-it-yourself fix.
10. Upgrade Storage or Memory If the Basics Are Not Enough
If you have worked through the steps above and the laptop is still slow, a hardware upgrade may be the answer — and it is usually far cheaper than a new machine. Replacing an old hard drive with a solid-state drive (SSD) is the single most effective upgrade for most older laptops, and it makes startup and app loading dramatically faster. Adding more memory (RAM) helps if you multitask heavily or keep many browser tabs open. Before buying anything, check your laptop’s manual or the maker’s support site to confirm which parts are upgradeable; some thin and light laptops have soldered storage and memory that cannot be changed. If your machine is not upgradeable and is still slow after all the software fixes, that is a fair sign it is time to start shopping for a replacement.
How to Speed Up a Slow Laptop: A Simple Maintenance Routine
The fastest laptops are the ones whose owners do a little upkeep on a regular basis. Once a month, restart the machine, check your free storage, and review startup programs. Once every few months, uninstall apps you no longer use and clear out old downloads. These small habits prevent the slow buildup of clutter that makes a laptop feel old before its time. And when you do need to test whether your fixes worked, a quick typing or speed check can be a fun benchmark — our words per minute test is a handy way to see how smoothly your keyboard and browser are responding after a cleanup.
If you use your laptop for creative work, keeping the system lean matters even more. Heavy apps benefit from free storage and a clean startup list, whether you are editing photos or generating images — if that is part of your workflow, see our roundup of the best AI image generator tools for options that run well alongside a tidy system. The bottom line is simple: knowing how to speed up a slow laptop is mostly about removing what you do not need, keeping what you use up to date, and giving the machine room to breathe. Work through the ten fixes in order, and most laptops feel years younger by the end of the list.
