  1. Cyberlab

The CyberLab (formerly Zookaware) PC maintenance tool will stop spyware, unwanted software, junk files, registry errors, and tracker cookies.

Cyberlab Scan feature treats Registry keys in the same way as locked files, and they can sometimes not be deleted. The problem does not lie with Cyberlab. It is simply a feature of the Windows operating system.

This registry cleaner adopts a similar approach to removing registry keys as it does to removing junk files. They show all registry keys that can be removed, and do not hide any in a follow-up scan in case they weren’t removed during the first scan.

  1. Storage Sense – the built-in free computer cleaner

The PC cleanup tool available on Windows 10 doesn’t need to be downloaded from the Internet. With Storage Sense, you can remove unwanted files from your system with a tool called Free Up Space.

The Windows cleaner features of Free Up Space are similar to those you would find in a standard Windows cleaner. Only one third-party app needs to be installed, and it is malware-free.

How to use Free Up Space on Windows 10?

  1. Go to Settings > System > Storage.
  2. Click on the “Configure Storage Sense or run it now” option.
  3. Scroll down and click on Clean Now.

Furthermore, you can also specify if you want to delete your Downloads folder after a particular number of days, or you can configure how temporary files related to apps are deleted.

Additionally, if you want Windows 10 to clean your hard drive periodically manually, you can enable the Storage Sense tool.

What are the Pros and Cons of Storage Sense?

  • Installing this software is not necessary.
  • It works without any problems. Automatically updates with Windows 10 updates.

  • It will automatically optimize your storage, clean your recycling bin, and organize your download folders.

  1. Disk Cleanup – free PC cleaner for older Windows versions

If you don’t want to do anything and want to have one of the best free computer cleaners for Windows 7 or Windows 8.1, then Disk Cleanup might be your best choice.

Alternatively, you can use the Disk Cleanup tool if you do not want to use Storage Sense. When you upgrade Windows, you can use this built-in utility to delete old installation files.

Disk Cleanup can be found by searching for its name in the Start Menu. Using this tool is somewhat slower than using Free Up Space on Windows 10, but you can still remove a lot of junk from your PC.

What are the pros and cons of Disk Cleanup?

  • Its UI has now become outdated due to Storage Sense’s replacement.
  • This application is responsible for the removal of junk files, temporary internet files, thumbnails, etc.
  • Large amounts of space can be freed up by removing older Windows installation data.
  • The Downloads folder and the Recycle Bin can be cleaned.
  1. CCleaner

Windows cleaner tools like CCleaner are probably the best known. The utility software is accessible on macOS as well as Windows 10 (and older versions). Ccleaner Professional Plus costs $29.95. The numerous features it offers in addition to the data removal functionality make it one of the best free PC cleaner apps. You can use it, for example, to delete data from your hard drive.

However, there has been growing skepticism about the effectiveness of this PC optimizer tool due to its features such as Active Monitoring which may put users’ privacy in doubt. Piriform has, however, taken steps to solve those problems. Nevertheless, when you use it, please be aware of which options have been enabled.

What are the pros and cons of CCleaner Free Version?

  1. Avast Cleanup

The tool from Avast does however come with a price tag. However, you can try it out to see if it meets your needs.

How does a computer cleaner work?

In the process of deleting your data, you might be interested in knowing exactly what data is being destroyed. There are several free Windows 10 clean-up utilities that promise to assist you in eliminating unwanted things like junk files, browser history, browser cookies, leftovers from uninstalled apps, etc.

You can also purchase a paid version of some of these tools. In this case, you get access to additional features such as one-click maintenance and so on.

How useful are these PC clean-up tools?

Although computer cleaning software can keep your machine clean and optimized, I won’t say that you should totally rely on it because there are some good practices every PC user should follow. In some cases, they may be helpful if you select the right instrument.

There are many evil fish in the sea, which is why various Windows cleaner tools are often questioned. Cleaning tools can slow down your computer more than before. In some cases, they try to trick you into installing unwanted software, and some kill essential system processes. All to speed up your PC.

It is even possible for some PC optimization tools to create issues that are nonexistent. Their goal is to make the user, who isn’t much tech-savvy, panic and pay for the software.

However, I’ve had a decent experience with a few free computer clean-up programs. I remember seeing significant improvements in the boot time of my old PC after CCleaner had removed the junk data.

Still, I won’t recommend using a random cleaning tool to fix your PC. As the saying goes, if it ain’t broke, don’t fix it.
