Here’s how to speed up a slow laptop:

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.
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 percent capacity. So if you check how much space is used up and you’re over 90 percent, 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 percent 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. It should show you the Processes tab by default.
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.

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.
