Does your laptop take forever to start, and then crawl the moment you open a browser? Before you start shopping for a new one, try this: most of the time, you can speed up a slow laptop in an afternoon, with no new parts and no money spent. Usually it’s not the laptop that’s dying — it’s clutter, too many programs fighting for attention, or a hard drive that’s full.
This guide walks through ten easy fixes to speed up a slow laptop without spending money, from the five-minute ones to the slightly bigger jobs. Try them in order, and check after each one — you might find the first two are enough.
1. Restart it properly
It sounds too simple, and that’s why people skip it. But a restart clears out temporary files and stops programs that have been running quietly for days. If your laptop has been on for a week, a proper restart — Start, then Restart, not just closing the lid — can make a real difference. Do this first, before anything else.
2. Stop programs starting with your laptop
One of the biggest reasons a laptop feels slow is that a dozen programs are starting up with it, and most of them you never asked for. On Windows, open Task Manager, look at the Startup tab, and turn off anything you don’t need the second your laptop turns on. On a Mac, the same idea lives in System Settings under General, then Login Items.
Be careful here — don’t turn off your antivirus or anything you don’t recognise. If you’re not sure what something does, leave it alone and look it up first. Microsoft’s own help page explains the Windows steps in detail.
3. Uninstall what you don’t use
Old games, trial software, a printer program for a printer you threw away — it all adds up. Go through your installed programs and remove the ones you genuinely don’t use. This frees up space and stops some of those programs running background bits you never see.
While you’re there, check your storage. If your drive is nearly full, your laptop will struggle. A good rule is to keep some free space — delete big files you don’t need, or move photos and videos to an external drive or cloud storage.
How to speed up a slow laptop by tidying the browser
Your browser is often the real culprit. Thirty tabs, half a dozen extensions, and a few video sites running in the background will slow down almost any laptop. Close tabs you’re not using — bookmark them if you might want them later — and look at your extensions. Keep the two or three you actually use, and remove the rest.
Clearing your browser cache now and then helps too, though don’t expect miracles from it. The bigger win is simply giving the browser less to do. If you’re choosing a new machine, the same thinking applies — our laptop buying guide explains what to look for so you don’t end up with the same problem again.
4. Check for updates — and then for malware
Out-of-date software can be slow software, and it can be unsafe as well. Run your system updates and let them finish. Then run a scan with your antivirus. You don’t need to buy anything fancy: the built-in protection on Windows (Windows Security) and on Mac does a decent job for most people.
Be suspicious of any tool that pops up claiming your laptop is full of errors and offering to fix them for a fee. Most of those are scams, or at best useless. Stick to the tools that came with your system, or one you know and trust.
5. The simple maintenance jobs
Two quick jobs are worth doing every few months. First, check that your files aren’t filling the drive — your operating system has a storage view that shows what’s taking up the most room, and it’s usually a surprise. Second, if your laptop still has an old-style hard drive rather than an SSD, defragmenting it (on Windows) can help; on an SSD, don’t bother — the system looks after that itself. Doing these small jobs regularly is one of the easiest ways to speed up a slow laptop and keep it that way.
If you’re not sure which kind of drive you have, Wikipedia’s page on solid-state drives explains the difference in plain terms.
6. When the free fixes aren’t enough
Try the free fixes first — they fix the majority of slow laptops. If yours is still crawling after all of them, the next step is usually more memory or a faster drive. Adding memory (RAM) or swapping an old hard drive for an SSD are the two upgrades that make the biggest difference, and for many laptops they’re not expensive.
Not every laptop can be upgraded, though — some newer thin models have parts soldered in. Check your model’s support page on the manufacturer’s website before buying anything, or ask a repair shop for a quick quote. And if a new machine is the answer, our Android vs iPhone guide shows the same approach applied to phones — buying for the life you actually have, not the one in the advert.
To speed up a slow laptop, you rarely need to do everything on this list. Restart, trim your startup programs, clear out the browser, and uninstall the things you don’t use — those four alone fix most complaints. Keep the rest in mind for the next time it feels sluggish, and back up your files before you change anything major. It’s the one job everyone puts off, and the one everyone regrets skipping.
Frequently asked questions
Why is my laptop so slow?
Usually it’s one of a few things: too many programs starting with the laptop, a full hard drive, too little memory for what you’re running, or a laptop that’s simply old. The fixes in this article start with the easy ones — a restart, removing startup programs, freeing space — and work up from there.
Will adding more RAM make my laptop faster?
It helps if the problem is running out of memory, which you’ll notice when the laptop struggles with several programs open at once. If the laptop is slow even with one program open, the cause is more likely a full or old hard drive, or too many programs starting up. Check what’s actually struggling before you buy anything.
How do I speed up my laptop for free?
Restart it, uninstall programs you don’t use, turn off the programs that start with Windows, and free up disk space. Those four are free and fix most slow laptops. After that, check for updates and run a malware scan — all free, and all worth doing before you spend money.
Should I replace the hard drive with an SSD?
If your laptop still has an old spinning hard drive, switching to an SSD is the single biggest speed improvement you can make. It’s also the most involved fix on this list, so it’s worth checking whether your laptop can take one, and whether the cost makes sense for its age.
