10 Best PC Cleaners & Optimizers For Windows PC in 2023

People often complain about slow PCs and how poor performance impacts their productivity and overall user experience. Over time, computers get slow down due to a variety of reasons, such as insufficient system resources, bloatware, outdated software/hardware, virus attack, and more.

Since everyone expects their devices to work efficiently and smoothly, a lot of users turn to forums like Quora and Reddit to seek solutions and advice on how to improve their computer’s performance. We’ve found a few threads filled with queries like

  • What causes computers to slow down?
  • Why does a computer break down or not work properly when it ages?
  • If my computer is running super slow, should I consider buying a new one?
  • I have brought a new PC. How can I maintain its stability?
  • My laptop has become really slow just after 2.5 years. How do I improve its performance to how it was when I purchased it?

If you can relate to any of the questions above, don’t worry! We’ll be helping you with a series of effective solutions to speed up your PC and restore its original performance.

Talking about the manual methods first, Windows 11/10 comes with a couple of inbuilt tools like Disk Cleanup, Disk Defragmenter, Device Manager, Task Manager, SFC tool & more. These pre-installed utilities help users to free up unnecessary disk space & manage resource usage. But, it’s important to note that, these tools provide a “very basic level” of cleaning and optimization. Hence, you may not be able to yield the maximum performance out of your desktop/laptop. An alternate solution that a lot of users prefer over these pre-installed tools is Third-Party Programs To Optimize PC.

These programs can perform a more comprehensive cleaning, as they typically have access to more system areas and can detect more junk files, temp files, duplicates & other redundant data, as compared to the built-in tools.

What Is A PC Cleaner?

A PC Cleanup tool is a dedicated software that helps users declutter and optimize their computers. It is designed with powerful capabilities to detect and delete unnecessary files, perform regular maintenance and improve the overall performance of your PC.

A computer cleaning utility generally includes features like a one-click cleaner, junk file remover, driver updater, startup manager, app uninstaller, registry cleaner, RAM optimizer & privacy protection. These tools can help in recovering valuable disk space, resolve common performance issues and enhance overall speed.
