Speed up your Windows with the best PC Cleaner software!


When you first bought your computer or laptop, it most likely ran smoothly and had few problems. However, it is easy for it to become clogged with multiple apps, files, and leftovers of installations over time. All of this can drastically degrade performance. That’s where PC Cleaner software comes to the rescue.

If you’re getting low storage warnings, it’s evident that you must do something about it. Although if you have more than enough spare capacity, it can have a major impact.

Windows includes several built-in tools to assist you to delete unnecessary files and applications. However, you’ll get the greatest results by using professional PC cleanup software. There are a lot of PC cleaner applications out there. While the ones below are all reasonable and provide a full service.

Most of these free PC optimizers even have premium counterparts that can handle more complicated tasks. Also, give additional capabilities like scheduled scans and secure file deletion if you want more functions.


Restoro PC Cleaner

Restoro doesn’t have the most extensive feature set we’ve seen. However, it does an excellent job of giving the necessities and managing them effectively without adding too many frills.

Through the powerful system repair tool, a variety of problems are looked for, listed if discovered and rectified. Built-in malware detection is included in all Restoro scans. Any suspect files will be discovered immediately. After that, you will be able to determine whether or not they should be removed.

You will gain from the power of Restoro’s exceptional real-time monitoring features if you have one unlimited use option. These are intended to assist you in keeping an eye on your computer. Moreover, detects potentially dangerous apps and security breaches before any harm is done.

Restoro’s full money-back guarantee should be self-explanatory. However, it basically implies that if you’re unhappy with the program’s performance, you may seek a full refund.

The only drawback of this PC Cleaner is that the free edition just allows you to use the software, not the repair tools.



CCleaner has been there for a long time, and a reason for its admiration is that it cleans parts of your computer that other free system optimization programs don’t.

The optimization program has a commercial version that adds real-time protection as well as cleanup scheduling, however, the free edition of CCleaner covers the essentials like removing temporary files, clearing browser caches, and deleting unneeded cookies while retaining the ones that are useful, and so on.

This is the free PC optimizer to attempt first if your PC is simply sluggish. This PC Cleaner doesn’t have all of the technical functions of applications like System Mechanic, but what it does clean is notorious for slowing down computers.

Razer Cortex

If your system is having trouble getting your game on, the Razer Cortex could be the solution. This free PC optimizer turns down inactive system programs, frees up RAM, and defrags your system to give you the best game performance possible.

While the improvements won’t make you leap up and down in delight – for most people, the benefits will imply marginally smoother images rather than dramatic speed increases. Razer Cortex does automate the laborious process of turning off superfluous applications and services when it’s set to play.

Iolo System Mechanic


Iolo System Mechanic removes junk files and superfluous software, guards against bloatware and unwanted auto-run settings, frees up RAM, and deletes logs, browser histories, and caches.

This not only frees up important system resources but also removes traces of your surfing activities, protecting your privacy.

Its PC optimization toolbox truly makes a difference; every time we’ve tested System Mechanic, we’ve noticed a big speed boost, particularly at startup. The free version is fantastic, but if you use it frequently, the two paid editions are well worth considering.

IObit Advanced SystemCare Free

IObit PC Cleaner

The free edition of IObit Advanced SystemCare covers basic housekeeping, while the Pro version includes internet speed-boosting, real-time optimization, deep registry cleaning, privacy protection, and 24/7 technical support, and the license covers three PCs.

IObit Advanced SystemCare’s UI is nicely designed, straightforward to use, and unlikely to intimidate even the most inexperienced PC user, regardless of the edition you choose. We’d subtract points for an installer that wants to install other apps – that’s not in line with the principle of keeping unwanted software off your computer – but they’re easy to prevent if you opt for a bespoke installation.

It cleans up folders and files you don’t need, cleans up the Windows registry, and fixes issues on your hard drive, all from a simple, elegant dashboard, just like the rest of the PC optimizers.

Ashampoo WinOptimizer

Ashampoo PC Cleaner

The most appealing feature of Ashampoo WinOptimizer is its versatility: you can check for trash files, broken registry entries, as well as browser cookies with a single tap, then delete them all with another.

You can also go further by clicking the ‘Details’ button and going over each scan result one by one. Unlike some other PC optimizers, Ashampoo WinOptimizer provides a detailed analysis of each problem it finds, describing what it is and why you should consider deleting it. You can then decide whether to delete it or keep it based on your research.

WinOptimizer also comes with a set of modules for doing normal maintenance activities like defragging hard drives and optimizing startup times. All of these things can be completed within Windows, but getting them all in one place is far handier than navigating through menus.


There are a lot of free PC cleaner software and optimizers out there that claim to make your computer run quicker, but not all of them live up to the hype. Since the release of Windows 11 in October, it’s more important than ever to ensure that your PC is set for the upgrade, as long as it satisfies the basic requirements.
