Features and Highlights

A good PC cleanup makes all the difference
As you use your computer, it piles up all kinds of junk: cache, log files, and whatnot. This junk gobbles up your disk space and drags down your computer’s performance. It knows exactly where to find useless files, and which of them are safe to remove. A few clicks — and you’re back on a fast, clean PC.

Get Windows Registry clutter out of the way
Imagine having to find something in a closet packed full of trash. It could take you hours. That’s how it works with Windows Registry: when it’s cluttered with outdated entries, your software and OS have trouble finding the right data in there. CleanMyPC keeps the Registry on your PC clean to make sure your computer is up to speed.

Uninstall the right way to keep your PC clean
Most Windows apps come with their own uninstallers — except they don’t always remove the entire program and leave behind useless cache files or toolbars. It wipes every trace of a program, even the leftovers that are typically overlooked. Because when you want something gone from your computer, you want it really gone.

Windows startup won’t slow you down again
Waiting forever for your PC to boot? That’s because of autorun programs that load along with Windows. Lighten the load on your system without rummaging through the settings: the tool shows you autorun items in a single list, so all it takes to disable them is a click. There’s no easier way to speed up a PC startup.

Cut down on extensions
Why put an additional load on your PC with toolbars and extensions you don’t even use? The program keeps add-ons within easy reach, so you can quickly spot the ones you don’t need and turn them off.

Erase your files securely
Did you know other people can recover the files you delete? Unless you delete them securely, of course. The software shreds your files and makes them impossible to recover, so you can be sure sensitive data is gone.

Protect your online privacy
It scans all your browsers to gather traces of your online activity in one spot. No need to dig through browser settings to clean up cookies or login data: just hit a button to wipe your entire online history clean.

Get rid of the hibernation file
Even if you never use Hibernation, there’s a file that stores a snapshot of your session in case you do — and it hogs gigabytes on your disk. Disabling it manually can be a hassle, but It makes that super simple.

Uninstall multiple apps
Want to remove several programs at once? Do it easily with the tool Multi Uninstaller. Unlike manual program removal, it doesn't require much time and effort.  Just pick whatever you want to remove, launch uninstallation and let Multi Uninstaller work its magic.

Clean leftovers
Programs leave junk even if uninstalled properly? Not on watch! The program automatically starts to scan for leftovers after the program is removed and cleans whatever remains.  As a result, no empty folders and unnecessary files after program removal. That means more space for fresh, new apps!

Uninstall any program
What if for some reason you can’t uninstall a program? The app will do the job, no matter if it is a third party program you installed on your own or a pre-installed Windows store app. You can uninstall any app you want. Well, almost any. Multi Uninstaller doesn’t remove system apps that are essential for your Windows performance.

Sleep well, uninstall safely
With Clean My PC you can be sure that your computer is in good hands. It includes the safety database to make sure you uninstall exactly what you want - no more, no less. Multi Uninstaller's interface is designed to minimize the risk of errors. So, keep calm and uninstall more with Clean My PC.

Note: Will only clean MB of junk from the system in the demo version. Requires .NET Framework.

Download CleanMyPC Latest Version

There are many companies and programs promising to clean and speed up your PC, for a modest price of course. Many of these applications will run your computer through an initial “diagnostic” which generally shows thousands of errors. These are usually not errors at all, but every individual instance of things like temporary files and cookies (which hardly have an effect on your computer’s speed anyways). This is a scare tactic to make you believe there are things severely wrong with your computer that you must pay them money to fix.

While these programs may do everything they claim, the functions that they use to clean and speed up your computer are already built into your operating system. Why throw your money away for products you already own?

Now that we know what to avoid, these steps will take you through the same process the paid PC cleanup/speed-up applications will do, for free! And a bonus is every utility on here can be set to run on a schedule, so you’ll be saving both money and time.

1. DISK CLEANUP

Run the Disk Cleanup tool included with Windows. This can most easily be found on Windows Vista and up by typing “Disk Cleanup” into your Start menu search bar. For older versions of Windows, from the Start menu point to All Programs->Accessories->System Tools and select Disk Cleanup.

Alternatively, simply find and right-click on the drive you want to clean up in My Computer, and select the option in the drop-down menu for Disk Cleanup. It’s focused on freeing up space on your hard drive, but it will also delete old temporary files and other useless things. You can even schedule a Disk Cleanup to clean your computer automatically.

2. CLEAR YOUR BROWSER HISTORY

While you shouldn’t expect a huge performance jump, clearing your browser history regularly or setting your browser to automatically clear its history when you close it can help speeds.

3. RUN DISK DEFRAGMENTER (BUT NOT ON SOLID STATE DRIVES)

As stated on Microsoft’s website, “Fragmentation makes your hard disk do extra work that can slow down your computer. Removable storage devices such as USB flash drives can also become fragmented. Disk Defragmenter rearranges fragmented data so your disks and drives can work more efficiently.” It speeds up access and write time by consolidating data that has become scattered naturally throughout the hard disk over time, and reducing the distance the head has to travel over the disk platter.

Solid state drives (SSD) do not require defragmentation because they read and write data differently than hard disk drives. There are no moving parts in a solid state drive and data is written in a scattered fashion across its storage cells. There is no head to reduce travel time for, and additionally, SSD cells have a limited amount of writes before they become error-prone or unusable, so fragmenting would actually do more harm than good.

Newer versions of Windows will let you analyze a disk first to see its level of fragmentation. Users all have their own preferences, but many say they will run Disk Defragmenter if the level of fragmentation is above 10%. Run it too often, and you won’t notice much of a difference.

4. RUN CCLEANER (OR A SIMILAR PROGRAM)

CCleaner is a great, trusted utility that cleans areas of your computer Disk Cleanup may not hit. Using this program you can also save some time clearing your browser history manually, CCleaner will do it for you in all browsers that you use. Its most used utility is its registry cleaner, which will remove unused and old registry entries that could be hindering performance. It is lightweight and can be set to run on a schedule, making cleanup even easier for you.

CCleaner can be downloaded here.

Another great “toolbox” program is Iobit’s Advanced SystemCare. There is a free and a paid version if you really like what you see and want access to some additional features (but the free version will do just fine for most users).

Advanced SystemCare can be downloaded here.

WRAPPING UP

Life is too short to waste time due to a slow computer, especially if you work online. For example, if you are an essay writer, nothing must distract you, and you need the necessary tabs and applications opened instantly. The tips we shared will help you speed up your computer. They are simple enough, so you don&#;t need to be a programmer to cope with the task! We hope they&#;re helpful to you.

The best free PC cleaners make it simple and easy to keep your desktop computer or laptop optimized and running smoothly.

There are many free PC cleaners and optimizers that claim to deliver noticeably faster performance, but not all live up to the hype. That's why we've tested all the most popular options and rounded up the ones that we believe will give your PC a noticeable speed boost, with no hidden extras or intrusive ads.

With Windows 11 rolling out to more users since its release in October, it's best to make sure that your PC is ready for the upgrade, as long as it meets the minimum requirements.

The best free PC optimizer available today is Iolo System Mechanic – a feature-packed toolkit containing everything you need to purge unnecessary files, fine-tune your PC's settings and protect your privacy at the same time. However, if your needs are more straightforward, we've also rounded up four other excellent tools that will give your PC a thorough spring clean without offering an intimidating number of options.

It's worth noting that you can do much of what these free PC optimizers do yourself using Windows' built-in system maintenance tools, but that's time consuming; what's really being sold here is convenience.

If you want more features, many of these free PC optimizers also have premium counterparts that can perform more advanced tasks, and offer additional tools like secure file deletion and scheduled scans.

Best free PC cleaner of in full:

Update: A recent change to Iolo's checkout process means you will be automatically subscribed to a $ (about £15 / AU$25) per month support package when you purchase a product. This is a very large extra charge, so make sure to double-check before entering your payment details.

Iolo System Mechanic removes junk files and unwanted apps, blocks bloatware and unwanted auto-run settings, clears out RAM and wipes various logs, browser histories and caches.

Not only does this free up key system resources, it also eliminates traces of your browsing activity to protect your privacy.

Its PC optimization toolkit really does make a difference; whenever we've tested System Mechanic we've found a significant speed improvement, especially at startup. The free edition is excellent, but the two premium versions – System Mechanic and System Mechanic Pro – are well worth considering if you find yourself using it regularly – and Iolo is offering a 70% discount (opens in new tab) with the voucher code TECHRADAR.

The genuine performance boost we saw after running System Mechanic made it our favorite PC optimizer. Read on for four more of the best apps around for speeding up your Windows PC.

Restoro doesn’t boast the biggest feature list we’ve seen, but it does a great job of providing the essentials and managing those well without adding too many unnecessary extras. 

Numerous problems are scanned for, listed if found, and repaired with the powerful system repair tool. All Restoro scans include built-in malware (opens in new tab) detection. Any suspicious files will be immediately identified, and you can decide whether or not they need to be removed.

If you have one of the two unlimited use plans, you will benefit from the power of Restoro’s excellent real-time monitoring tools. These are designed to help you keep tabs on your computer, identifying potentially dangerous apps or security breaches before any damage is caused. 

This should be quite self-explanatory, but Restoro’s full money-back guarantee basically means that you can request a full refund if you’re not happy with the program’s performance. 

The only negative is that the free version allows you to run the software, but not any of the repair tools.

IObit Advanced SystemCare comes in two forms: a free edition version that covers basic house cleaning, and a Pro version that adds internet speed-boosting, real-time optimization, privacy protection, deep registry cleaning and 24/7 technical support, and the license covers three PCs.

Whichever edition you choose, IObit Advanced SystemCare's interface is well designed, easy to use and unlikely to frighten even the newest PC user. We'd deduct points for an installer that wants to add additional programs - that's hardly in keeping with the philosophy of keeping unwanted stuff off your computer - but they're easy to avoid if you choose a custom installation.

Like most of the PC optimizers here, it cleans up files and folders you don't need, neatens up the Windows registry and corrects errors on your hard drive – all via a simple, slick dashboard.

Over the course of this review, you’ll see that I found the software both easy to use and effective. It cleaned up more than 5GB of unwanted files from my PC and fixed more than registry issues in a matter of minutes. Aimed at users who want an all-in-one solution to keeping their PC fresh, CleanMyPC incorporates many existing Windows tools and builds on them to offer a simple and non-technical option for computer maintenance.

We’ve also tested CleanMyMac, another maintenance tool made for Mac users, also from MacPaw. I called it “perhaps the best Mac cleaning app” out there. Today, I’ll be taking a look at CleanMyPC, the Windows-based alternative, to see whether MacPaw can replicate that success for PC users.

No, it isn’t. While there is a free trial, and it’s free to download, you will be limited to a one-time MB cleanup and up to 50 items fixed in your registry. The free trial should be viewed as more of a demo than a free version, as most users will hit those limits almost immediately.

Important Update: CleanMyPC is going to partially sunset. Starting from December , it won’t receive regular updates, only critical ones. Also, there will be no subscription option to purchase, only a one-time license for $ And Windows 11 is the last OS version to be supported by CleanMyPC.

Why Trust Me for This CleanMyPC Review

My name is Alex Sayers. I&#;ve been using many different PC maintenance tools for at least 12 years now, always looking for ways to improve and streamline my PC use. For several years, I&#;ve tested and written about software too, trying to give readers an unbiased look at the tools on offer from an amateur&#;s point of view.

After downloading CleanMyPC from the MacPaw website, I&#;ve been testing every feature of the software for a few days, comparing it to similar tools that I&#;ve used in the past across two Windows PCs with different hardware and software onboard.

In writing this review, I&#;ve tested every feature of CleanMyPC, from the baseline cleanup options to the &#;shredder&#; facility, taking the time to get to know the software in detail. Over the course of this article, you should get a good idea of whether this tool is right for you, and get a look at the features and pros and cons of using it.

Detailed Review of CleanMyPC

So we&#;ve taken a look at what the software offers and how you can get your hands on it, and now I&#;ll run through each of the eight tools that it provides to see what benefits it can bring to your PC.

PC Cleanup

We&#;ll start with the main selling point of this cleaning program, its file cleanup tool.

I was pleasantly surprised to find that, having not done a scan for a few weeks, CleanMyPC found just over 1GB more unneeded files to delete than CCleaner did &#; around GB of cache, temp, and memory dump files in total.

CCleaner does give you the option of seeing exactly which files have been found and flagged for deletion, something which the MacPaw program lacks, but there&#;s no denying that CleanMyPC does a thorough search of your hard drive.

As a nice added touch, you can also set a size limit on your recycle bin through CleanMyPC, flagging it to automatically empty if it gets too full. Also in the options menu is the choice to allow the cleaning of attached USB devices, saving you space on your USB drives and external HDDs.

The cleanup process is as simple as can be, with just a &#;scan&#; and a &#;clean&#; button being all that stands between users and plenty of reclaimed disk space. The scan and clean were quick too, both on SSDs and older HDDs, and the checkbox list of discovered items gives you some control over what files you delete.

Registry Cleaner

Just as with the cleaning application, CleanMyPC appeared to be much more thorough in its search for registry &#;issues&#; to fix than CCleaner was, finding in total while Piriform&#;s software identified just seven.

Again, the scan was simple to run and quick to complete. The vast majority of issues identified by these two programs&#;and any others I&#;ve ever tried, for that matter&#;are issues which users would never have noticed, however, so it&#;s difficult to assess the effect that a quick registry cleanup like this might have on your PC. Still, it&#;s reassuring that MacPaw has made their tool so thorough in performing its duties.

As I mentioned earlier, I do wish that CleanMyPC had a built-in option for backing up your registry before you start &#;fixing&#; items in it, if just for a little peace of mind, but it is something that you can do manually outside of the program if you choose.

Uninstaller

CleanMyPC&#;s Uninstaller function comes in two parts. First, it runs the selected program&#;s own uninstaller, the one that the developer built, and then it runs CleanMyPC&#;s own service to tidy up the files and extensions typically left behind by the uninstallation process.

It&#;s unlikely that you&#;ll regain much disk space from a function like this. In my experience, it&#;s usually just empty folders left behind or registry associations. It could, though, help to keep everything organized and structured on your disk and avoid any registry issues in the future.

This process was quick and simple, so I see no reason not to use it if you don&#;t trust a program&#;s built-in uninstaller to remove every last hint of itself.

Hibernation

Hibernation files are used by Windows as part of an ultra-low power state called, you guessed it, hibernation. Used mostly on laptops, hibernation is a way for your computer to consume practically no power at all while still remembering your files and the PC&#;s state before you switch it off. It&#;s similar to sleep mode, but instead of open files being stored in RAM until the computer is woken up again, information is saved to your hard drive to consume less power.

Desktop users will usually never make use of this function, but Windows creates and stores hibernation files all the same, potentially taking up a large chunk of disk space. In my case, Windows was apparently using a little more than 3GB for hibernation, and CleanMyPC offers a quick way to both delete the files and switch off the hibernation function entirely.

Extensions

The program&#;s built-in extension manager is a simple tool for removing unwanted browser extensions and Windows gadgets, displaying a list of each extension enabled in all of the browsers installed on your PC.

With the click of a button, any extension can be uninstalled in seconds. Perhaps it&#;s not useful for most users, but it might be a lifesaver for those whose browsers are cluttered with multiple add-ons or those who want to clean multiple browsers at once.

It could also be handy if your browser or an extension is either corrupted or infected with malware. Often malicious or corrupted extensions and add-ons will prevent the browser from being opened or remove your ability to uninstall the offending item, and CleanMyPC might be a good way to work around that.

Autorun

Staying on top of run-at-startup programs is a simple way of keeping your PC running quickly, and slow boot-up times are one of the biggest complaints that people often have with older PCs that haven&#;t been looked after. Quite often multiple programs can be added to the startup list without users realizing it, which adds seconds of boot-up time with no real benefit to the user.

Managing which programs run when you start Windows is a fairly simple process without making use of any additional software. However, MacPaw&#;s tools do a good job of presenting a simple list to users, complete with an ‘on-off&#; switch for each item.

The one thing I would like to see included in future versions is a way to add to your list of startup programs. Again, it is something which can be done manually outside of CleanMyPC, but it would be a nice touch to be able to both add and remove programs in one place.

Privacy

The privacy tab allows you to manage what information is stored in each of your installed browsers, with the option to individually clear caches, saved history, sessions, and cookie information from each one.

It&#;s something that could be managed manually with the options built into each browser, but CleanMyPC&#;s interface offers a quick and simple way to manage them all at once. It&#;s a worthwhile thing to have if you&#;re giving your entire PC a refresh.

Shredder

The final tool in MacPaw&#;s suite is the &#;shredder&#;, a method of securely erasing files and folders from your computer that you want to be unrecoverable. Designed with sensitive information in mind, like financial records or password files, Shredder deletes the files you select and then overwrites them up to three times to ensure that they can&#;t be brought back.

There are other tools out there that do the same job. Both they and the Shredder facility do a good job of granting you some peace of mind when handling sensitive information or disposing of an old HDD.

Reasons Behind My Ratings

Effectiveness: 4/5

CleanMyPC works well. It quickly identified a lot of files taking up space on both of the PCs I tested it on. It found more than registry issues to fix and made quick work of uninstalling programs and managing the extensions and autorun settings that I asked it to.

There are some minor missing features that I&#;d like to see added — registry backups, the option to add autorun programs, and a more detailed display of the files it intends to delete — but those are small tweaks that possibly wouldn&#;t be missed by most users.

Price: 4/5

Even though the program comes with a limited trial, it is clearly intended more as a brief demo than a free stripped-back version of the full program. You&#;ll hit its limits very soon after installation.

While it&#;s true that all of the features could be replicated with a suite of free alternatives, CleanMyPC packages them well in an easy-to-use form and takes some of the technical know-how out of your hands. And for some people, $ is a small price to pay for a hassle-free approach to PC maintenance.

Ease of Use: 5/5

I can&#;t fault how easy it is to use CleanMyPC. Within the few short minutes I had downloaded and installed the program, my PC had been scanned and I was already reclaiming space from unwanted files.

Not only is it quick and easy to use, but the layout and look of the UI is great, too. It&#;s clean and simple, presenting all of the information that you need without having to click through complex menus or understand technical jargon.

Support: 3/5

Support from MacPaw is good. There&#;s an extensive online knowledge base for CleanMyPC, they have an email form through which you can contact their team, and you can download a page manual from their website for the program.

I do think it would be great, however, if they offered phone support or an online chat on their website. Even help via social media would be a welcome addition, especially for families paying almost $90 for a set of licenses.

Alternatives to CleanMyPC

CleanMyPC is good, but it might not be for everyone. While it is easy to use and offers an all-in-one approach to PC maintenance, many people won&#;t need or use all of the features available, and some might instead look for more in-depth versions of a particular function.

If CleanMyPC doesn&#;t take your fancy, here are three alternatives that provide similar functionality (you can also see our PC cleaner review for more options):

• CCleaner &#; Developed by Piriform, CCleaner offers a very similar cleanup and registry fixing service. The premium version adds scheduling, support, and real-time monitoring.
• System Mechanic &#; Claiming to provide a point diagnostic check of your PC, this software offers several tools for cleaning your disk, speeding up your computer, and boosting performance.
• Glary Utilities Pro &#; A suite of tools from Glarysoft, Glary Utilities offers many of the same features while also adding disk defragmentation, driver backups, and malware protection.

CleanMyPC vs CCleaner

For several years now, I&#;ve been a big fan of CCleaner, a disk cleanup tool from Piriform (later acquired by Avast), that I use personally on my PCs and recommend to friends and family.

A little later on in this review I&#;ll show you a comparison of the disk cleaning tools within CleanMyPC and CCleaner, but those aren&#;t the only similarities that the tools share. Both programs also include a registry cleaner (again, compared further down the page), a browser plugin manager, autorun program organizer, and an uninstaller tool.

For the most part, the tools on offer from each are very similar &#; they function in a very similar way and produce comparable results. CCleaner does have some nice added extras that I feel could improve CleanMyPC, such as scheduled cleanups, disk monitoring, and a disk analyzer, but I&#;d be lying if I told you that I&#;d used any of those additional tools with any regularity.

Take a look through my results in the rest of the review and decide for yourself which of these tools is right for you. CCleaner does, for me, have the edge in terms of the number of options and customizability available, but it&#;s undeniable that CleanMyPC is more user-friendly and probably a better option for less advanced users.

Conclusion

If you&#;re looking for an all-in-one solution for your PC maintenance, you can&#;t go far wrong with CleanMyPC.

From clearing up space and shortening boot times to secure file disposal and registry fixes, this program does offer something for everyone. While advanced PC users might not make use of all of the tools, or might work around them using built-in Windows alternatives, it is a handy program to fall back on if you&#;re looking to quickly give your computer a refresh.

If only for its ease of use, intuitive design, and efficiency when searching out unwanted files to delete, CleanMyPC is a worthwhile addition to any PC user&#;s maintenance toolbox.
