15 Best Free CCleaner Alternatives in 2021

When you first purchased your laptop or desktop, it would boot up in seconds and open programs in the blink of an eye. But as time went on, it started to slow down to the point that you could walk away to make a sandwich and return just in time for your application to be ready to use.

In the past, CCleaner was the best registry cleaner that could free up disk space and get rid of junk files that served no purpose. It was easy to use and capable of returning your laptop or desktop to its peak condition. Sadly, CCleaner’s reputation has taken a hit as of late due to malware and viruses infecting the software and users of the program.

These incidents have forced many to search for the best CCleaner alternatives. Thankfully, there are plenty of options on offer that can get rid of junk files, clear disk space, and help your hard disk load up programs in a reasonable time.

But which CCleaner alternative should you install on your machine? Don’t just download any registry cleaner to your laptop or desktop. Choose one of the best CCleaner alternatives listed below.

What Does a CCleaner Alternative Do?

When you’re looking for an alternative to CCleaner, you’re wanting an application that is a registry cleaner, removes junk files, and eliminates any other corrupted items on your hard disk. It helps identify unwanted files that are no longer valid, were supposed to be temporary, or serve no purpose at all.

Instead of downloading multiple applications to solve individual problems on your device, a CCleaner alternative provides an all-in-one solution that can fix any issues with a couple of clicks of your mouse. It will identify the junk files and look for ways to free up disk space. You’ll then get presented with the results and can choose to proceed with removing the unwanted files or investigate further to ensure you don’t delete anything important.

You could choose to purchase a CCleaner alternative. However, there are plenty of free options available. Here are some of the best CCleaner alternatives that you can download right now, and that won’t cost you a cent.

3.    Glary Utilities

You can choose to use Glary Utilities to solve a lot of problems on your Windows or Android devices. Just like CCleaner, it is a registry cleaner and removes your unwanted files.

How to Keep You and Your Devices Protected

CCleaner would help extend the life of a laptop or desktop by ensuring that the system wasn’t getting bogged down with unnecessary files and system registry issues. It made cleaning out hard disks and repairing problems easy as it would normally only take one click of the mouse to make all your problems disappear.

Sadly, CCleaner can no longer be trusted to protect your device, but many alternatives provide the same features. In some instances, they offer even more protection for your laptop or desktop.

In addition to a CCleaner alternative, you also need a VPN to protect you and your device while you’re online. A virtual private network can help hide your sensitive information and provide you with complete anonymity when you’re browsing websites. But not all VPNs are identical. Some can throttle your bandwidth, and others come with data caps.

Don’t risk picking the wrong virtual private network for your needs. Check-in with VPN Testing first and ensure that you, your device, and your files won’t need any extra cleaning while you’re online.
