There are a lot of free and best PC cleaners and optimizersout there that claim to make your computer run quicker, but not all of them live up to the hype. That's why we've put all of the most popular alternatives to the test and compiled a list of the ones we think would give your PC a considerable speed boost while avoiding any frills or obtrusive adverts.
With the release of Windows 11 on October 5, it's a good idea to check sure your PC is up to date and fulfills the minimal requirements.
It's worth noting that you can do a lot of what these free PC optimizers do yourself with Windows' built-in system maintenance tools, but doing so takes time; what's really being sold here is convenience.
Many of these free PC optimizers also have premium counterparts that can handle more complicated tasks and give additional options like secure file deletion and scheduled scans if you want more capabilities.
Iolo System Mechanic
Iolo System Mechanic is the greatest free PC optimizer available today. It's a feature-rich toolbox with everything you need to delete superfluous files, fine-tune your PC's settings, and secure your privacy all at once. If your requirements are easier, we've compiled a list of four other fantastic applications that will thoroughly clean your PC without overwhelming you with options.
Update: Due to a recent change in Iolo's checkout procedure, when you purchase a product, you will be automatically subscribed to a $19.99 (about £15 / AU$25) per month support package. This is a significant additional fee, so double-check before inputting your payment information.
Iolo System Mechanic cleans out junk files and unnecessary apps, prevents bloatware and undesirable auto-run settings, frees up RAM, and deletes logs, browser histories, and caches.
This not only frees up important system resources, but it 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 good, but the two premium editions – System Mechanic and System Mechanic Pro – are well worth considering if you use it frequently – and Iolo is currently providing a 70% discount with the code TECHRADAR.
We chose System Mechanic as our preferred PC optimizer because of the genuine performance gain we experienced after running it. Continue reading to learn about four more of the greatest programs for speeding up your Windows PC.
Restoro doesn't have the most extensive feature set we've seen, but it does an excellent job of giving the necessities and managing them effectively without adding too many frills.
With the powerful system repair tool, a variety of problems are looked for, identified if discovered and rectified. Malware detection is included in all Restoro scans. Any suspect files will be discovered instantly, and you will be able to determine whether or not they should be removed.
You will benefit from the power of Restoro's exceptional real-time monitoring features if you have one of the two unlimited use options. These are intended to assist you in keeping an eye on your computer, detecting potentially dangerous apps or security breaches before any harm is done.
Restoro's full money-back guarantee should be self-explanatory, but it basically implies that if you're unhappy with the program's performance, you may seek a full refund.
The only drawback is that the free version just allows you to use the software, not the repair tools.
IObit Advanced SystemCare Free
The free edition of IObit Advanced SystemCare covers basic housekeeping, while the Pro version adds internet speed-boosting, real-time optimization, privacy protection, deep registry cleaning, and 24/7 technical assistance. For a year, the license costs US$20 (about £15, AU$25), and it 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 deduct points for an installer that wants to install other programs - it's not in keeping with the principle of keeping unwanted software off your computer - but they're easy to prevent if you use a custom
It cleans up files and folders 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 below.
Piriform CCleaner has been around for a while, and one of the reasons for its continued popularity is that it cleans portions of your computer that many other free system optimization applications don't.
The optimization program has a commercial version that adds real-time protection and cleanup scheduling, but the free edition of CCleaner covers the essentials like removing temporary files, clearing browser caches, 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. It doesn't have all of the technical functions of applications like System Mechanic, but what it does clean is notorious for slowing down computers.
The most appealing feature of the Ashampoo WinOptimizer is its versatility: you can check for garbage files, broken registry entries, and browser cookies with a single click, then delete them all with another.
You can also go deeper by selecting 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 as defragging hard drives and optimizing startup times. All of these things can be completed within Windows, but having them all in one place is far more convenient than navigating through menus.
If your system is having trouble getting your game on, the Razer Cortex could be the answer. This free PC optimizer disables inactive system programs, frees up memory, and defrags your system to provide the greatest potential game performance.
While the differences 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 time to play.
If you use one ofthe best PC Cleanersand Registry Cleaners we've suggested above, you can't go wrong.
