To speed up a slow laptop, restart it, install pending updates, stop unnecessary apps from launching at startup, free up storage space, and check for malware. Those five steps fix most slowdowns on both Windows and Mac without spending money. If the machine is still sluggish afterward, a memory upgrade or a switch to a solid-state drive is usually the next best move.
The Metromsk.Com tech desk tested this order of steps because it starts with the quickest wins and works toward the bigger fixes.
Key Takeaways
- A full restart and pending updates solve more slowdowns than most people expect.
- Startup apps and browser tabs are the most common hidden drains on memory.
- Leave a healthy amount of free drive space so the system has room to work.
- Sudden slowness plus pop-ups or crashes can signal malware, so run a scan.
- Older laptops with spinning hard drives often feel new again after an SSD upgrade.
Start With the Quick Wins
Closing the lid is not the same as restarting. Laptops that sleep for weeks accumulate stuck processes and memory leaks. A full restart clears them and often lets waiting updates finish installing.
Updates matter for speed and safety. CISA’s guidance on keeping software updated explains that updates fix security flaws and bugs and can improve performance, and it recommends turning on automatic updates.
- Windows: Settings > Windows Update > Check for updates.
- Mac: System Settings > General > Software Update.
Update your browser too, since it is probably the app you use most.
Trim Startup Apps and Background Programs
Many programs quietly add themselves to startup, so they load every time you sign in and keep running in the background. Chat apps, cloud sync tools, game launchers, and printer utilities are frequent culprits.
On Windows
Press Ctrl + Shift + Esc to open Task Manager. Select the Startup apps page, sort by startup impact, and disable anything you do not need the moment you log in. On the Processes page, sort by CPU or Memory to see what is using resources right now.
On Mac
Open System Settings > General > Login Items and remove apps you do not need at login. Then open Activity Monitor from Applications > Utilities and check the CPU and Memory tabs for anything unusually heavy.
Tame Your Browser
Dozens of open tabs and a pile of extensions can consume more memory than everything else combined. Close tabs you are not using, bookmark the ones you want to keep, and remove extensions you no longer recognize or need.
Unknown extensions are also a security risk. If a browser add-on appeared without your permission, remove it and review the steps in our guide on how to protect your online accounts.
Free Up Storage Space
When a drive is nearly full, the operating system has little room for temporary files and memory swapping, and everything slows down. Aim to keep a healthy share of the drive free. It is the fix Metromsk.Com readers most often skip.
- Uninstall apps you have not opened in months.
- Empty the Downloads folder and the Recycle Bin or Trash.
- Move photos and videos to an external drive or cloud storage.
- On Windows, turn on Storage Sense under Settings > System > Storage.
- On Mac, review System Settings > General > Storage for recommendations.
Check for Malware
If your laptop suddenly slowed down and you also see pop-ups, a changed home page, or new toolbars, malware could be the cause. The FTC lists “your computer slows down, freezes, or crashes” first among its signs of malware.
Run a full scan with your built-in security tools, such as Microsoft Defender on Windows, or with reputable security software. Then change passwords for important accounts from a clean device if anything suspicious turns up.
Troubleshooting Table: Symptom and Likely Fix
| Symptom | Likely cause | What to try |
|---|---|---|
| Slow right after login | Too many startup apps | Disable startup items |
| Slow with many tabs open | Not enough memory (RAM) | Close tabs, remove extensions, consider more RAM |
| Long waits opening files | Full or aging drive | Free up space; upgrade to an SSD |
| Fan loud, laptop hot | Dust or blocked vents | Clean vents, use on a hard surface |
| Pop-ups and crashes | Possible malware | Run a full security scan |
| Laggy video calls | Weak Wi-Fi or background uploads | Move closer to router, pause cloud sync |
Keep It Cool and Powered Properly
Laptops slow themselves down when they overheat to protect their components. Use your laptop on a desk rather than a bed or couch, and gently clean vents with compressed air. A raised stand also improves airflow and, as our article on managing back pain while working from home notes, a screen at eye level is better for your posture.
Power settings matter too. On Windows, pick a balanced or best-performance power mode when plugged in. On Mac laptops, check the Battery settings for low power mode, which saves energy but can reduce speed.
Consider Hardware Upgrades
If software fixes do not speed up a slow laptop, the hardware may be the bottleneck. Replacing a spinning hard drive with a solid-state drive is often the single biggest improvement for older laptops. Adding RAM helps if you routinely run out of memory.
Many newer laptops, including most MacBooks, have memory and storage soldered to the board, so check your model’s specifications before buying parts. If upgrades are not possible, it may be time to replace the machine.
When a Fast Laptop Matters Most
A responsive computer makes a real difference for video calls, online classes, and remote work. Smooth video is especially important for telehealth appointments, where a frozen screen can interrupt a conversation that matters. If you work from home, our remote team productivity tips show how to get more from a well-tuned setup.

Frequently Asked Questions
Why is my laptop so slow all of a sudden?
A sudden slowdown usually points to a recent change: a large update installing in the background, a new app added to startup, a nearly full drive, or malware. Restart first, then check Task Manager or Activity Monitor to see which process is using the most CPU, memory, or disk activity at that moment.
Does adding more RAM make a laptop faster?
Extra RAM helps when you regularly run out of memory, such as when using many browser tabs or large apps at once. It will not fix a slow hard drive or overheating. Check memory usage in Task Manager or Activity Monitor first, and confirm your laptop’s memory is upgradable before buying.
Is it safe to reset my laptop to factory settings?
A factory reset is safe and often effective, but it removes your apps and settings, and some options erase personal files too. Back up everything important to an external drive or cloud storage first, note any software licenses you need, and treat a reset as a last resort after other fixes.
How often should I restart my laptop?
Restarting at least once a week is a good habit for most people, and more often if you notice slowdowns. A full restart clears memory, ends stuck processes, and lets updates finish installing. Simply closing the lid or using sleep mode does not provide the same refresh for the system.
