The number of free PC cleaners and optimizers available claim to fix several performance issues, but not all of them are up to the job. Our team of experts tested all the most popular options and selected the ones without hidden extras or excessive advertising.

Iolo System Mechanic is a powerful free PC optimizer that will help you remove unnecessary files, fine-tune various settings on your PC, and even protect your privacy. For those of you looking for an easier solution, we've rounded up four other awesome tools that will thoroughly clean your PC without overwhelming you with options.

You can accomplish much of what these free PC optimizers do with Windows' built-in system maintenance tools; however, Windows built-in tools are more convenient.

Many of these free PC optimization programs are also available in more advanced versions with additional features such as scheduled scan and safe file deletion.

Below are the best free PC optimization programs currently available.

Advanced IObit system without care

IObit Advanced SystemCare is available in two versions:a free edition that offers basic housekeeping and a Pro edition that offers faster internet connection, real-time optimization, privacy protection, deep registry cleaning and online technical support. The license covers three PCs for $20 (about £15, AU$25) per year.

The user interface of IObit Advanced SystemCare is intuitive and designed to make it easy to use, even for the most novice. Adding unnecessary programs to your computer is not consistent with the philosophy of installing only what you need, but you can avoid that with a custom install.

Using its sleek dashboard, CleanMyPC cleans up unnecessary files and folders, fixes errors on your hard drive, and cleans up your Windows registry.

Piriform CCleaner

This free program has been around for a long time, and it's remained popular because it keeps your PC clean in a way that other freeware utilities don't.

While there is a paid version of the optimization toolkit that provides real-time protection and scheduled cleanups to get rid of temporary files, browser caches, and unwanted cookies, the free edition of CCleaner prevents these things from happening.

Here is the free PC optimizer you should try first if your computer is slow. Compared to apps like System Mechanic, it lacks all the advanced features, but what it does clear is known to slow down computers.

Cyberlab Technologies

Using Cyberlab (formerly known for Zookaware ) for PC maintenance, you can clean, optimize, speed up and fix errors on your computer by removing spyware, unwanted programs, junk files, registry errors, tracking cookies, etc.

There is no antivirus software on Cyberlab. The Cyberlab program gives you access to all the junk files, hidden programs, and tracking cookies that can slow your PC down like a Galapagos turtle. Antiviruses usually don't cover what they do.

In short, Cyberlab is a perfect tool for anyone who wants to keep their PC fast and safe. Try it and you will definitely like it.

They have very good reviews on Trustpilot which shows their legitimacy.

Mechanic of the Iolo system

In addition to removing junk files and clutter, Joe Iolo System Mechanic blocks bloatware, uninstalls autorun settings, cleans RAM, and deletes browser cookies, history and caches, and various logs.

This not only frees up valuable system resources, but also protects your privacy by erasing traces of your browsing activity.

System Mechanic's optimization toolkit really makes a difference; each time we tested it, we saw significant speed improvements, especially when starting up. If you use System Mechanic frequently, then System Mechanic or System Mechanic Pro is worth considering.


One of AshampooWinOptimizer's biggest selling points is its flexibility – with just one click, you can scan for junk files, broken registry entries, and browser cookies, then erase them all.

Additionally, you can select the "Details" button to browse the results of each scan one by one. AshampooWinOptimizer identifies all the problems your computer is having and explains exactly what they are and why they matter. Other PC optimization programs do not do this. Afterwards, you can determine whether or not you want to keep it.

In addition to optimizing boot processes and defragmenting hard disks, WinOptimizer provides maintenance modules. While each of these tasks can be done within Windows itself, having them all in one place is much more convenient than navigating menus.

Last words

Cyberlab, Iolo, Advanced SystemCare are our top recommended PC cleaning solutions. They are all free, but they also have the PRO versions which are worth using.
