How to speed up a slow laptop or PC (Windows 10, 8 or 7) for free

Published by on febbraio 20, 2018 in Utilities

Whether it happens gradually over time or all of a sudden, trying to work with a slow computer can be seriously frustrating. Even if you’re fairly diligent with the maintenance of your laptop or PC, it’s surprising how quickly things slow down. If you’re experiencing such issues and running Windows 10, 8, or 7, this post is for you!

Thankfully, you don’t have to trade in your computer just yet. In fact, you can take several steps to give it a bit of a boost in the performance department. From simple decluttering to a few more technical operations, even the slowest computer can return to its old self.

In this post, we reveal 13 things you can do to speed up a slow laptop or PC using Windows 10, 8, or 7. For this article in particular, we’ll be focusing on system performance issues rather than those related to the network you’re using. We’re running Windows 10, so we’ll be using this version for the directions and screenshots. However, any adjustments for Windows 8 and 7 will be noted directly below, if applicable.

1. Close system tray programs

If your computer is off to a slow start, then it’s possible you have too many programs starting up at the same time as Windows itself. Items in the system tray often launch at startup and then stay running while you use your computer.

To access these items, click the upwards arrow toward the right side of your taskbar.

If there are any programs you don’t need to have running, right-click them and close.

2. Stop programs running on startup

Similar to programs running in the tray, other programs that automatically run on startup can slow down your computer. Some you may actually want to run, such as antivirus software, but others may be unnecessary.

Right-click the taskbar and select Task Manager or hit Ctrl-Shift-Escape to launch. Head to the Startup tab and you’ll be able to view each item that runs on startup, along with its impact.

Go through these and decide which ones don’t need to start automatically. This process is especially beneficial to performance if you can disable some of the high impact ones. But note that some of these programs are vital for Windows to operate. For example, the ones with Microsoft listed as the publisher are probably best left alone. If you aren’t sure, either leave it, or try a Google search to find out more.

To disable, simply right-click and hit Disable. Remember, you’re not disabling the program, just the fact that it runs on startup.

3. Update your OS, drivers, and apps

You’ve probably heard that keeping your software up-to-date is a good idea for security. This is true and it can help performance too. Windows will automatically send you a notification when an update is available. You just need to make sure you don’t keep putting it off.

If you think you might have missed an update, you can always check. Go to Start and click Settings or the settings icon. Then go to Updates & Security>Windows Updates.

Aside from your OS, drivers and apps should be kept up-to-date too. Again, this is good for both security and performance. If you think you might have missed an update, a quick online search should tell you which version you should be using.

4. Delete unnecessary files

Just like our closets and drawers, our computers get cluttered. While you can’t really see it, you know it’s there, and it could be having a negative impact on your computer’s performance. This is especially true if you deal with a lot of large files, such as high-resolution images, audio files, and videos, on a day-to-day basis.

Free up space by making a habit of deleting files and folders each week and emptying the recycle bin afterwards. Doing this regularly means it’s more likely you’ll remember exactly what’s in the files and folders and won’t be so concerned about mistakenly deleting something important.

Handy tip: HDDs usually run at peak speed until they reach roughly 90% capacity. So if you check how much space is used up and you’re over 90%, that’s probably what’s slowing things down. SSDs slow down more gradually as they fill up, so it’s good to stay on top of things. It’s recommended not to fill an SSD to more than 75% of its capacity.

5. Find programs that eat up resources

If you find that your computer is suddenly running significantly slower, chances are there is a particular program to blame. One way to identify the culprit is to go into your task manager and find out what’s eating up your resources.

Right-click the taskbar and select Task Manager. Click More details to find out information about the programs that are currently running on your computer.

The Processes tab within the Task Manager screen.

You can click each header to sort the list according to which applications are using the most of that particular resource. If you need to close something, try closing the actual application first. If it won’t close, come back to the Task Manager screen, right-click the application, and hit End task.

Windows 7: Instead of accessing Task Manager, you’ll need to search for System Configuration.

6. Adjust your power options

Windows comes with several preset ‘power plans’ to suit your needs. The default is set to Balanced, which takes into account performance and energy consumption. But the latter is only really a concern if you’re running off battery of trying to keep the electricity bills down. As such, you may want to change these settings.

Go to Control Panel>Hardware and Sound>Power Options>Create a power plan.

Power plan options.

You can start with an existing plan and adjust accordingly. Basic options include how long the display stays on for when you’re inactive, how long before the computer goes into sleep mode, and screen brightness. These won’t really affect your computer’s speed, but if you go into Change advanced power settings, you can make more adjustments that will have an impact.

7. Uninstall programs you don’t use

We often install huge programs without realizing how much space they’re taking up. If you think that might be the case, then you can easily uninstall any programs you don’t use. Even if it’s a program you do use now and again, if it’s particularly big, it might be worth simply reinstalling each time you need to use it.

To uninstall a program, head over to Control Panel>Programs>Programs and Features.

The Programs and Features screen.

Go though the programs and decide which ones, if any, you don’t need. If you’re unsure about a particular program, you could simply use a search engine to find out more. Alternatively, you can also use a tool like the aptly named PC Decrapifier to help you distinguish the good from the bad.

8. Turn Windows features on or off

While you’re in the Programs and Features screen, you might want to check to see if there are any Windows components you don’t need. Click Turn Windows features on or off and you’ll see a list of these components.

You’ll want to be careful you don’t turn off anything you actually need. So again, a search for anything you’re unsure about is a good idea.

9. Run a disk cleanup

Windows comes with a built-in tool for cleaning up junk that accumulates over time. To access the Disk Cleanup tool, go to Control Panel>System and Security>Administrative Tools, and select Disk Cleanup from the list.

The Disk Cleanup options.

Here, you can select the types of files you want to get rid of and click OK. Then click Clean up system files and choose any system files you want to remove.

10. Defragment your hard drive

Over time, files on your hard drive become fragmented. As your computer now has to check in multiple places for the pieces, it can run more slowly. The term ‘defragment’ sounds a little dramatic, but it basically means putting those files back together so your system can run more efficiently.

In fact, it’s something that Windows 10, 8, and 7 do automatically on a set schedule. The default schedule is once a week, but you can go in and manually run it if you suspect there’s an issue.

First, it’s important to note that you only need to do this if your computer uses a traditional mechanical Hard Disk Drive (HDD). A Solid State Drive (SSD) works differently from an HDD, and there is no need for defragmentation. If you have both, only defragment the HDD.

Go to My Computer and right-click the hard drive (by default named WINDOWS (C:) though you may have renamed it). Then go to Properties>Tools and under Optimize and defragment drive, click Optimize.

The Tools tab of the drive properties screen.

You’ll then get an Optimize Drives screen popup.

A list of the drives to be optimizied.

Note that in the above screenshot, all of the drives are SSD. These do not need to be defragmented. As in the image, Analyze will be grayed out for SSD drives, but will be available for hard drives.

Select an HDD drive and click Analyze to see how fragmented it is. A good rule of thumb would be to keep it below 5%. If it’s above, you can click Optimize to defragment the disk.

If you have an SSD, you’ll notice Optimize is actually an available option. Clicking it will run the TRIM command which will wipe data that is no longer considered in use.

Windows 7: Look for Disk Defragmenter using the search bar and select an HDD under Current status.

11. Adjust or disable graphics and animations

More recent versions of Windows come with lots of graphics, including animations such as fading effects and flyouts. These help make the application appear more sleek and refined and contribute to a better overall user experience. On the other hand, they can also slow down your computer.

Thankfully, it’s simple to adjust these settings and hopefully save a little processing power. Go to Control Panel>System and Security>System>Advanced system settings. Then, in the Performance section, hit Settings and you’ll have a full list of options.

The Visual Effects tab within Performance Options.

You can select Adjust for best performance (this will remove all visual effects) or opt to remove some individually. It’s a matter of preference, but fade and shadow features are some you could probably live without.

Windows 7: Search for Performance Information and Tools, select Adjust visual effects, and use the Visual Effects tab.

12. Check for malware

Malware (malicious software) is a broad term used to describe malicious programs that could cause harm to your computer. It can come from various sources, including email links, software downloads, and even ads. Aside from potentially causing permanent damage to your system, some forms of malware can cause your computer to run slow.

Having good antivirus software installed can help protect against malware, as well as other threats. Some solid free options are available, but if you’re willing to pay a fee, we recommend Bitdefender, VIPRE, or McAfee.

If you suspect malware is already affecting your computer, you can check it using a scanner such as Zemana AntiMalware. You can then remove it using a removal tool like Malwarebytes Anti-Rootkit. We’ve tested both of these products and were very satisfied with the results.

13. Disable Cortana

While the Windows 10 digital assistant, Cortana, is a handy feature, it uses up a lot of resources and also poses a privacy threat. Cortana used to be easily removed but in the up-to-date versions, it’s a little trickier. Nonetheless, if you’re willing to make an edit to your system’s registry, it can be done.

14. Upgrade your hardware

If you’ve tried all of the tricks above, it might be time to invest in some new hardware. Here are a couple of things you may want to consider putting some money into.

  • Add an SSD: While HDDs offer more space for a lower prices, adding an SSD can make your computer run much faster.
  • Add more RAM: If you have an older system, it may have too little memory to run modern applications efficiently. What’s more, if you use a lot of programs simultaneously, you may not have enough Random Access Memory (RAM) to carry you through. Installing a new RAM kit could give you the boost you need.

A few more tips

Of course, it’s not just your operating system slowing things down. Some computer habits and other apps and systems could be contributing to an overall sluggish experience. Here are a few more tips to get you up to speed.

  • Keep your computer clean: This may sound obvious, but accumulated dust and grime can actually slow down your computer. Physically cleaning your computer regularly could help speed it up and prevent overheating.
  • Remove unused browser extensions: These can slow down your browsing experience so it’s worth doing some regular housekeeping there.
  • Use a memory-saving extension: Speaking of extensions, if you’re a Chrome user, there is actually an extension available which reduces the memory footprint of open tabs.
  • Restart regularly: Sometimes all you need is a fresh boot. Restarting your computer can enable updates to take effect and shut down stuck programs. When you’re taking a break, it could be a good time to hit restart while you go and make yourself a cuppa.
  • Run fewer simultaneous programs: Just like multitasking can be detrimental to our productivity, running lots of programs simultaneously can be detrimental to your computer’s speed. Make a habit of closing programs instead of just minimizing them and you should see some improvement.
  • Reinstall the operating system: If you’ve tried everything and you’re still running into problems, a last resort might be to use a fresh install of Windows.

Keeping things running smoothly

Once you’ve cleaned up your computer by implementing some of the tips above, no doubt you’ll want to keep it running at top speed. To avoid getting frustrated with lackluster performance, it’s a good idea to schedule a monthly cleanup. Use the above list of tips as a handy checklist and you’re all set.
