How to Speed Up a Slow Laptop: 12 Practical Fixes
Discover 12 practical ways to speed up a slow laptop, improve performance, and make everyday tasks run more smoothly.
A slow laptop can make a five-minute task feel like a 30-minute job.
You click an app and wait. You open a browser tab and the laptop freezes. You try to switch between programs and suddenly the fan sounds like it's preparing for takeoff.
Before you assume the laptop is finished, though, find out what is actually slowing it down.
A laptop can become sluggish because too many programs are running, the storage drive is nearly full, background processes are consuming resources, the system is overheating, or the hardware simply isn't keeping up with what you're asking it to do. Microsoft identifies limited storage, too many startup apps, outdated software, and aging hardware among common contributors to slow Windows performance.
The good news is that several of these problems can be fixed without buying a new computer.
Here are 12 practical fixes, starting with the easiest.
1. Restart the Laptop Properly
This sounds almost too simple, but don't skip it.
If you've been putting your laptop to sleep for days or weeks instead of restarting it, background processes and temporary system conditions can accumulate.
A restart gives the operating system a clean start and can close programs or processes that have become stuck.
On Windows
Select:
Start → Power → Restart
On Mac
Choose:
Apple menu → Restart
If the laptop is simply sluggish because of a temporary software problem, you may notice an improvement immediately.
However, if the laptop is still slow after restarting, don't keep restarting it repeatedly. Move on to finding the actual bottleneck.
2. Find Out What Is Using Your CPU, RAM or Disk
This is probably the most useful step in the entire guide.
Instead of guessing why your laptop is slow, look at what the computer is struggling with.
On Windows
Press:
Ctrl + Shift + Esc
to open Task Manager.
Look at:
- CPU
- Memory
- Disk
- Network
Microsoft describes Task Manager as a system monitor that can show resource consumption and help manage startup applications.
If one application is constantly consuming an unusually large amount of CPU or memory, you've found a potential suspect.
On Mac
Open:
Applications → Utilities → Activity Monitor
Activity Monitor lets you examine CPU, memory, energy and other resource usage. Apple specifically recommends it for identifying troublesome apps and processes when a Mac becomes sluggish.
Don't kill random processes
This is important.
Seeing a process using CPU doesn't automatically mean you should terminate it.
Some processes belong to the operating system or essential software.
Start with applications you recognize. If an unfamiliar process is consistently consuming significant resources, investigate what it belongs to before ending it.
3. Stop Unnecessary Apps From Starting Automatically
One reason a laptop can feel painfully slow is that you've installed dozens of programs that quietly launch whenever the computer starts.
You may not even realize they're running.
Common examples include:
- Messaging applications
- Game launchers
- Cloud-storage utilities
- Meeting software
- Update managers
- Printer utilities
- Music applications
Windows
Open:
Task Manager → Startup apps
Review the programs listed there and disable applications you don't need launching automatically.
Microsoft identifies excessive startup applications as one contributor to poor Windows performance.
Mac
Go to:
Apple menu → System Settings → General → Login Items & Extensions
Review applications that are allowed to open when you log in.
What should you leave enabled?
Don't disable everything just because it appears on the list.
Your antivirus, hardware utilities, synchronization tools you actually depend on, and other essential software may need to start automatically.
The goal is not zero startup apps.
The goal is fewer unnecessary ones.
4. Free Up Storage Space
A nearly full drive can make a laptop feel much worse than expected.
On Windows, Microsoft notes that running low on storage can contribute to slower performance and can also interfere with Windows updates.
Windows
Go to:
Settings → System → Storage
Windows breaks storage down into categories such as installed apps, temporary files, and system/reserved storage.
Look for large:
- Downloads
- Videos
- Old installers
- Temporary files
- Unused applications
- Duplicate files
Windows also provides Storage Sense, which can automatically remove certain temporary files and help maintain free space.
Mac
Check your storage through:
Apple menu → System Settings → General → Storage
Start by removing things you genuinely don't need.
Don't obsess over making the drive nearly empty. You simply want enough working room that the system isn't constantly fighting for space.
5. Uninstall Programs You Don't Use
Look through your installed applications.
You will probably find programs you haven't opened in months.
Some may have been installed for a single project. Others may be games you stopped playing. Some may have come bundled with another program.
Uninstalling unused software can:
- Recover storage
- Reduce background processes
- Remove unnecessary startup items
- Reduce update activity
Windows
Go to:
Settings → Apps → Installed apps
Mac
Review your applications and remove software you no longer need.
Be careful with programs whose purpose you don't recognize.
Before removing something, search for its name or check whether it belongs to a driver, security tool, or hardware component.
6. Close Browser Tabs You Aren't Using
Your browser can become one of the biggest resource consumers on the laptop.
If you routinely have 30, 50 or 100 tabs open, don't be surprised when the computer starts struggling.
This becomes particularly noticeable when you're running:
- Multiple video tabs
- Web-based editors
- Online meetings
- Large spreadsheets
- AI tools
- Web applications
- Multiple browser windows
You don't necessarily need to close everything.
Start by closing tabs you haven't used recently.
You can also use your browser's tab-management features to save important pages for later instead of keeping them running indefinitely.
A useful test
If your laptop becomes noticeably faster after closing a large number of browser tabs, the browser workload was probably contributing to the problem.
If nothing changes, look elsewhere.
7. Reduce the Number of Programs Running in the Background
Closing a window doesn't always mean the program has completely stopped running.
Some applications continue operating in the background for:
- Notifications
- Synchronization
- Updates
- Cloud backups
- Messaging
- Hardware monitoring
This can consume CPU, memory and network resources.
Open Task Manager on Windows or Activity Monitor on Mac and look at what's actually running.
Ask yourself:
“Do I need this program running right now?”
If the answer is no, close it normally.
Again, avoid randomly terminating system processes just to make the resource list look cleaner.
8. Update Windows, macOS and Your Important Apps
Sometimes a slow laptop is running outdated software.
Updates can include bug fixes, compatibility improvements, security fixes and performance changes.
Windows
Go to:
Settings → Windows Update
Then check for available updates.
Microsoft recommends installing available Windows updates when troubleshooting system problems.
Mac
Go to:
Apple menu → System Settings → General → Software Update
Also keep important applications updated.
However, don't expect every update to magically transform an old laptop into a fast one.
Updates can fix software problems, but they can't turn weak hardware into powerful hardware.
9. Check Whether the Laptop Is Overheating
If your laptop is fast when you first turn it on but becomes extremely slow after 20 or 30 minutes of demanding work, heat deserves attention.
You might notice:
- Loud fans
- A very hot underside
- Sudden performance drops
- Stuttering during demanding tasks
- The laptop becoming slow during gaming or video editing
Heat can cause a laptop to reduce performance to control temperatures.
Start with simple fixes
Make sure:
- Air vents aren't blocked.
- The laptop isn't sitting on a bed or thick blanket.
- Dust isn't covering ventilation openings.
- The cooling system has room to breathe.
A hard, flat surface is generally better than a soft surface that can block airflow.
If the laptop is several years old and overheating regularly, professional cleaning or thermal-system maintenance may be appropriate.
Don't open the laptop if you're not comfortable doing so.
10. Scan for Malware
A laptop that suddenly becomes slow can sometimes have unwanted software running in the background.
This is especially worth investigating if you also notice:
- Unexpected pop-ups
- Unknown programs
- Browser redirects
- Unusual CPU usage
- Strange extensions
- Unexpected network activity
On Windows, use Windows Security to run a malware scan.
Microsoft's device-health guidance also recommends using security tools when malware may be contributing to system problems.
Don't install five different “PC cleaner” or antivirus programs because one website told you they will make the computer faster.
More security software isn't automatically better.
Use a reputable security solution and investigate suspicious behavior.
11. Check Whether You Have Enough RAM
RAM matters when you're trying to run several demanding programs simultaneously.
For example, you might have:
- A browser with many tabs
- Photoshop
- Microsoft Word
- Spotify
- A video call
- Several background applications
If the laptop doesn't have enough memory for the workload, the operating system may rely more heavily on storage, which can make multitasking feel sluggish.
Windows
Open Task Manager → Performance → Memory.
Look at memory usage while the laptop is slow.
Mac
Open Activity Monitor → Memory.
Apple's Activity Monitor shows Memory Pressure, which indicates how efficiently the Mac is handling memory. Apple notes that yellow or red memory pressure can indicate that the system may need more memory resources.
Don't judge RAM by percentage alone
Seeing high memory usage isn't automatically a problem.
Modern operating systems intentionally use available memory for caching and other purposes.
What matters is whether you're experiencing slowdowns and whether the memory indicators show genuine pressure.
12. Consider an SSD or Hardware Upgrade
Sometimes you've done everything you reasonably can—and the laptop is still slow.
That's when you need to consider whether the hardware itself is the limiting factor.
One particularly meaningful upgrade for older laptops is replacing a traditional hard disk drive (HDD) with a solid-state drive (SSD), if the laptop supports it.
An SSD can make everyday tasks such as:
- Starting the operating system
- Opening applications
- Loading files
- Searching through folders
feel dramatically more responsive compared with an aging mechanical drive.
RAM can also make a difference if the laptop has insufficient memory and supports an upgrade.
But check compatibility first
Not every laptop allows RAM or storage upgrades.
Some newer laptops have components that are soldered to the motherboard.
Before buying anything, check the exact model and determine:
- Whether the storage can be replaced
- Whether additional RAM can be installed
- What type of SSD it supports
- The maximum supported RAM
- Whether opening the laptop affects warranty or service options
How to Know What Is Actually Causing the Slowness
Instead of trying all 12 fixes randomly, use the symptoms as clues.
| What you notice | Possible cause to investigate |
|---|---|
| Slow immediately after startup | Too many startup apps |
| Slow with many browser tabs | RAM or browser workload |
| Slow when storage is nearly full | Insufficient free storage |
| Fan constantly running | Heavy CPU usage or heat |
| Slow only during gaming | CPU/GPU limits or overheating |
| Programs take a long time to open | Slow storage drive or heavy system load |
| Suddenly slow with strange pop-ups | Malware or unwanted software |
| Slow when multitasking | Insufficient RAM |
| Old laptop slow at everything | Hardware limitations |
These aren't diagnoses. They're starting points.
The important thing is to measure before making major changes.
What You Should NOT Do to “Speed Up” Your Laptop
There's a lot of questionable advice online about making computers faster.
Be careful with claims that tell you to:
Delete random system files
You could create a much bigger problem than the original slowdown.
Disable every Windows service
Some services are essential for Windows and your hardware.
Install several “RAM booster” programs
Your operating system already manages memory. A random optimizer isn't automatically going to give you more physical RAM.
Use registry cleaners without understanding what they change
A registry-cleaning program isn't a magic performance button.
Disable security software
A tiny performance improvement isn't worth exposing your computer to unnecessary security risks.
Keep deleting caches every day
Caches exist for a reason. Removing them isn't a substitute for fixing an actual performance problem.
If Your Laptop Is Still Slow After All 12 Fixes
At this point, stop looking for another magical setting.
The hardware may simply be reaching its limits.
Microsoft notes that older PCs with outdated hardware may not see significant improvement from software-based performance fixes. Microsoft also lists consistently high CPU, memory or disk usage, low storage, slow startup and increasingly slow everyday tasks among signs that a PC may be reaching the point where replacement should be considered.
That doesn't automatically mean you need a new laptop.
First ask:
What do I use this laptop for?
If you mainly browse the web, write documents and watch videos, a hardware upgrade may be enough.
If you're trying to edit 4K video, run modern games or use demanding professional software, the laptop's CPU, GPU or other hardware may simply be inadequate for the workload.
A Simple 15-Minute Slow-Laptop Check
If you don't want to spend your entire afternoon troubleshooting, do this:
First 3 minutes
Restart the laptop.
Next 3 minutes
Open Task Manager or Activity Monitor and check CPU, memory and disk activity.
Next 3 minutes
Check how much free storage remains.
Next 2 minutes
Disable unnecessary startup/login applications.
Next 2 minutes
Close programs and browser tabs you're not using.
Final 2 minutes
Check for system updates and run a security scan if something looks suspicious.
Then use the laptop normally.
If it's noticeably faster, you've probably addressed a software or resource problem.
If it isn't, investigate heat, storage hardware, RAM and the age/specifications of the laptop.
Final Thoughts
A slow laptop isn't always a sign that it's dying.
Sometimes the problem is surprisingly simple: too many startup programs, a nearly full drive, an overloaded browser, excessive background activity, or a program consuming far more resources than it should.
The most useful habit is to stop guessing and look at the evidence.
On Windows, Task Manager can show whether CPU, memory or disk activity is unusually high. On Mac, Activity Monitor provides similar visibility into CPU and memory usage.
If storage is nearly full, clean it up. If one application is consuming enormous resources, investigate it. If the laptop is overheating, address the cooling problem. If RAM is consistently under pressure, consider whether an upgrade is possible.
And if an older laptop remains slow after reasonable software maintenance, don't waste hours searching for a secret “turbo” setting.
Sometimes the most practical solution is a hardware upgrade or accepting that the machine has reached the limits of what its hardware can comfortably handle.
