If your computer feels like it’s taking ages just to open a file or load a webpage, it’s time for a cleanup. Slowdowns are a common occurrence, but that doesn’t mean you have to accept them. Today, I’m diving deep into how to clean up a slow computer so you can get back to a fast, efficient experience.
Just like our homes need regular cleaning, so do our computers. Over time, unnecessary files, bloated programs, and even malware can slow down your once-speedy system. The good news? You don’t need to be a tech genius to tidy up your PC. Follow these detailed steps, and you’ll have your computer running faster in no time.

Find Resource-Hungry Programs
A common culprit for a slow computer is resource-hungry applications. Your computer’s resources are like its energy; if an application is taking too much, there’s less left for everything else. A runaway process or an application with a memory leak can hog the system’s resources, causing your entire system to slow down.
To see what’s draining your computer’s energy, open the Task Manager by pressing Ctrl + Shift + Escape or right-clicking the taskbar and selecting Task Manager. In Windows 8, 10, and 11, the Task Manager provides a detailed overview of which applications use the most CPU, memory, and disk resources. Sort by these headers and look for anything using an unusually large amount. If something looks off, select it and click End Task to force it to close.
Close System Tray Programs
Have you ever noticed that tiny arrow on the bottom right of your screen? It’s home to your system tray, where programs run silently in the background. Many of these start automatically when you boot up your computer, consuming resources even if you aren’t actively using them.
Click the up arrow icon to reveal hidden system tray icons, then right-click any applications you don’t need running and close them. A leaner system tray means your computer has more resources to spare, which directly translates to improved performance.

Disable Startup Programs
While closing system tray applications helps, it’s even better to stop unneeded programs from launching in the first place. Many apps assume you want them to start every time you turn on your computer, but all they really do is slow down your startup.
To manage startup programs, open Task Manager again, and click the Startup tab. Here, you can disable the programs you don’t want launching on startup. Windows will even tell you the impact of each program on startup time, helping you make smart choices about what to disable.
Lighten Your Web Browser
For many of us, the web browser is our most-used application—and, unsurprisingly, it can also be one of the biggest contributors to a slow computer. Over time, we tend to install all kinds of add-ons and extensions that make our browser slow and memory-hungry.
Go to your browser’s settings and remove extensions you no longer use. Less clutter means better performance. Additionally, enabling click-to-play plugins will prevent unnecessary content, like auto-playing videos, from eating up your system’s resources.

Scan for Malware and Adware
No discussion of cleaning up a slow computer would be complete without addressing malware and adware. Even if you haven’t noticed anything suspicious, your system could be infected with software designed to run in the background—using your resources and slowing you down.
Run a full system scan using your antivirus program, and consider using Malwarebytes to look for potentially unwanted programs (PUPs) that antivirus software often misses. These could be tracking your web usage or showing extra ads, all while eating away at your computer’s speed.
Free Up Disk Space
If your hard drive is nearly full, your computer will struggle to find enough space to store temporary files, which can make it feel painfully slow. Thankfully, freeing up space is easy—and you don’t need any third-party software to do it.
Use the Disk Cleanup tool in Windows to delete temporary files, system cache, and other unneeded items. Just search for “Disk Cleanup” in your Start menu, and follow the prompts. You’d be surprised how much of a difference having extra storage can make.
Uninstall Unnecessary Programs
Most of us have old programs installed that we never use. They clutter our systems, take up valuable disk space, and may even have background processes running without us knowing.
Open the Control Panel, go to Programs and Features, and uninstall anything you don’t use. Be careful, though—if you’re unsure about a program, it might be best to leave it alone or research it first.
Reduce Visual Effects
Windows comes with several visual effects that, while pretty, can slow things down—especially on older systems. If you’re not too concerned with looks and just want your computer to perform as fast as possible, turning off these effects can help.
Press Windows Key + X, select System, and then Advanced System Settings on the left. Under the Performance section, click Settings and choose Adjust for best performance. This will turn off all animations. Alternatively, select Custom and pick and choose which visual effects you’d like to keep.

Defragment Your Hard Drive (Only for HDDs)
If you’re still using a mechanical hard drive, you should occasionally defragment it. Modern Windows versions do this automatically, but if you’ve recently moved around a lot of files, running the Disk Defragmenter tool manually might be helpful.
However, if you have an SSD (Solid State Drive), defragmentation isn’t necessary. SSDs access data differently and benefit from a process called optimization instead, which Windows also does automatically.
Reset Your PC for a Fresh Start
If all else fails, resetting your PC can often breathe new life into it. Modern versions of Windows have a Reset this PC feature that reinstalls Windows while keeping your personal files. It’s an effective way to get rid of junk without manually uninstalling everything.
Go to Settings > Update & Security > Recovery and select Reset this PC. Follow the prompts to get a clean slate—without having to track down your original Windows installation media.

Upgrade to an SSD
Finally, if you’re still struggling with a slow PC, it might not be a software issue—your hardware might need an upgrade. If you’re using a mechanical hard drive, upgrading to an SSD can make a massive difference. SSDs are significantly faster than traditional drives, and the upgrade can make your computer feel brand new.
Conclusion
Cleaning up a slow computer may seem daunting, but it’s really just about breaking it down step-by-step. From shutting down unnecessary startup programs to ensuring your browser is running smoothly, every little tweak adds up. Regular maintenance goes a long way toward keeping your PC running like the day you bought it.
So, if your PC is running at a snail’s pace, start with these tips today. Your computer—and your patience—will thank you.
