Best PC Cleaner Tools for 2021

Even though the built-in tools that come with Windows 10 and other operating systems are steadily advancing and becoming more useful, there is occasionally a requirement for high-caliber PC cleaning software. Perhaps a person is attempting to breathe new life into an older computer, or perhaps they just can’t seem to get a more recent model to function properly.

There are many high-quality PC cleaner tools available today that can be used in place of going to a store, where the cost could potentially be in the hundreds of dollars, in order to get immediate assistance. Because the vast majority of them are offered in some form of a free version initially, it is reasonably simple to comprehend from the very beginning.

Which businesses provide the very best of everything? These five choices are the most effective out of all the best options available right now in the year 2021. They have been around for the most part for quite some time, but their emphasis on continuously making improvements over the course of time in order to address any issues that may arise makes them worthwhile. The countdown to the start of the new year has now officially begun.

#1 Iolo System Mechanic

It doesn’t matter whether you’re using System Mechanic or one of the many other products that iolo offers to improve computer performance; the company has become one of the most trusted names in the industry as a whole. System Mechanic, which is available in a variety of iterations for users to test out, is the company’s most well-known and widely used utility.

People can get a pretty good idea of what to anticipate by using the free version, and the paid versions range in price from about $40 to $60, with very good discounts being offered regularly to both first-time customers and existing customers. One purchase grants unlimited access to the product for all members of the same household. That means that the utility can be downloaded onto any computer that requires assistance, and it can be used for the cost of a single licence.

Because of its superior performance in all aspects, iolo System Mechanic has earned the position of leader on this tally. When only a basic scan is being performed at first, a large number of corrections will already be in progress. People have the option to do a quick scan or a deep scan, which provides them with a reasonably accurate idea of what they can anticipate in the future. The scans are lightning fast and extremely effective, resolving even the most stubborn of issues in a matter of minutes in many cases.

There is a substantial amount of additional content that is included with the utility in general when one invests in one of the paid versions. A person will immediately notice an increase in the speed of their CPU as well as the speed of their downloads. Even the time it takes for the computer to start up will be cut down significantly, which is great news considering the number of people whose computers waste time trying to load far too many programmes at the beginning.

The premium versions include built-in features that are, from a confidentiality point of view, superior to those offered by competitors. iolo System Mechanic takes things to a higher level by optimising the changes made by Windows 10’s built-in tools to the greatest extent possible, despite the fact that Windows 10 has made quite a few advancements with those tools. Users who use iolo System Mechanic report feeling more secure as a result of the software’s ability to take over and handle any situation that may arise.

Iolo System Mechanic Ultimate Defense will provide the greatest number of utilities that can assist in accelerating a computer, making it the best option from a purely financial point of view. Many people are likely to discover that their computers will behave very differently compared to how they did previously. A person is provided with a handy walk-through explanation to fix anything that might be getting in the way, whether it be focusing on privacy issues, managing programmes that load for no reason, or anything else in between. It is very simple to use, even for people who have very little experience with computers. As a result, even though it contains a lot of information, it does not give the impression that the user is responsible for figuring out how everything operates.

Understanding what free means

Some people are confused when they begin the shopping process because they see the word “free” next to so many different versions of the product. There is a plethora of free software to clean up your computer, but most of it comes with certain restrictions. There are very few genuine exceptions to the rule that businesses will demand financial compensation from customers in order to access more premium features.

The consumer will be relieved to hear the good news that they will have the opportunity to test out the free version first, which will make everything a little bit more convenient. If it seems like a tool that is simple to use and effective to some degree when it is free, spending a little bit of money on it will bring so much more to the table than it would otherwise bring.

It’s possible that licencing is the most significant of all the hidden costs. There will be some tools that can only be obtained by purchasing a licence for them. This means that a person who owns both a laptop and a desktop computer will not be able to install the software on either device without paying an additional fee for doing so. This is something that a lot of people find to be rather annoying, and it has the potential to turn people away from certain businesses. That is one of the reasons why iolo System Mechanic has been consistently rated as being among the best in the industry. They have always provided unlimited licences for use within the same household, which has allowed customers to save a significant amount of money when managing the computers of a family.

Other buying factors worth considering

Still can’t decide? There are a few other aspects of the purchase that might not be all that important to some people, but for others, the decision will ultimately be based on what they find out. It is always beneficial to take a closer look at a few of the remaining options in order to determine which one is the most logical choice.

Technical support

However, despite the fact that each of these PC cleaning tools is intended to be very user-friendly even in the absence of any kind of technical assistance, this is not always the case. It’s possible that an extremely basic problem arises, and the individual in question is clueless about how to address it.

There are two primary varieties of technical support that the majority of these businesses provide for their customers. The first is an online resource that addresses a selection of those frequently asked questions. It makes a lot of sense to get some kind of assistance in this area because a lot of people have the same few problems, and it’s not always easy to solve them on your own.

One more choice is to contact customer service via email, live chat, or the telephone in order to receive technical assistance. It is always nice to have a quick response whenever there is any kind of technical issue, even though there are many problems that are not particularly urgent.

iolo System Mechanic is the company that does the best job with this particular aspect. They never stop working to ensure that clients who put money into their business have access to the best tools possible to make the most of what they buy. Some people, at first, do not recognise the myriad of ways in which the utility can be of assistance. When all of the features are explained, people ultimately realise that they have more available to them than they initially thought they did.


Windows 10 is the most popular operating system at the moment, but it frequently receives updated versions from Microsoft. The only way for a PC cleaning tool to be useful is if there are constant updates as well. Taking this into consideration, it is in your best interest to work with a well-established and reputable company rather than a fledgling one. In this industry, there have been some startups that have been successful, but overall, it’s a gamble to invest in one. Because nobody knows for sure whether or not they will bring everything to the table, it is safer to rely on a solution that has a proven track record.

Most of the time, updates will be performed automatically, and they shouldn’t take very long at all. Strong utilities will sooner rather than later provide a solution to any new problems that could be causing a slowdown in the system’s performance. Customers always appreciate it when free updates are made available that improve the functionality of their purchase, but major surprises rarely occur out of the blue.

#2 Restoro

#2 Over the course of its existence, Restoro has proven itself to be an excellent choice for people who use Windows. They offer a free trial version that has some limitations, but the paid versions are what propel them to the number two spot in the rankings. One licence can be purchased for $30, while three licences can be purchased for $40. This brings their prices pretty much in line with those of the majority of the other choices on this list, and the fact that it is more effective overall gives it an advantage.

In general, Restoro is a fairly comprehensive solution that is able to fix computers in a short amount of time. It does a very good job of identifying websites that could be harmful to the computer and removing any threats that may still be present. Even though certain computer dangers appear to be dormant at times, they always retain the potential to become active and cause a significant amount of damage at a later time.

If you want to fix problems with the Windows registry, you won’t have much luck finding a solution that’s better overall than Restoro. Restoro, much like System Mechanic further down, does an excellent job of ensuring that everything on the computer continues to function normally for the longest amount of time possible. It is just as important to make corrections in the here and now as it is to organise things for the future.

Restoro is a wonderful choice for people who have some experience working with computers and enjoy doing things in a slightly more hands-on manner. There is the option to perform repairs manually, but it is strongly advised that this be done only by those who are experienced and knowledgeable in the field. If a person is trying to fix something without having a particularly strong understanding of the bigger picture, they are setting themselves up for all kinds of problems.

Restoro is extremely close to taking the top spot on this list, but it falls a notch or two short in terms of its overall ability. The ability to treat very specific issues puts System Mechanic over the top, in addition to the fact that their suite contains a few more helpful tools than their competitors’ does.

#3 Norton Utilities Premium

Even the most inexperienced computer users will be familiar with Norton because of the wide variety of products that the company offers. When it comes to utilities for cleaning up a computer system, Norton Utilities Premium is among the best choices available today. People will trust the brand, and the price is among the most competitively priced premium options. People will also appreciate the premium features.

A person can significantly boost their computer’s speed for a fee of about twenty dollars per year. It is very good at fixing some of the most common problems that occur with computers, and a single purchase grants support for Windows 10 all the way back to Windows 7.

The fact that it does not have the same complex features that the top two choices do makes it less desirable than the other options, despite the fact that it is very good at handling the more straightforward problems. It is very effective at performing the tasks that are required of it, but it would be nice to see a little bit more effectiveness overall. Having an optimization tool that is very user-friendly and comes from a company that is highly regarded brings with it undeniably some advantages. Nevertheless, it is possible that it will not offer all of the answers that a person is looking for in the end.

#4 Advanced SystemCare

There are a lot of different options available, but one of the best ones to test out is the free version of Advanced SystemCare. They provide a large number of tools that can be tried out for no cost in order to determine how they might be of assistance, and some of the most fundamental problems can even be resolved by using these tools. People who require a bit more can get their hands on a premium version at a price that is not prohibitively expensive, particularly if the company is holding one of the many sales it holds throughout the year. The fact that it is one of the least expensive choices available does not change the fact that it is ranked fourth on this list; this is due to the fact that it is lacking in several key areas.

To begin, Advanced SystemCare does not clean up as much junk data or eliminate as many potential virus problems as some of the other products that are currently available. Comparing the various available choices can be challenging at times, but this option does not provide the most thorough cleaning that one could find. Something a little bit deeper would be nice to have, but it might come at a higher price.

One more annoying aspect of Advanced SystemCare is that, in comparison to other companies, it does not appear to provide as many options for protecting users’ privacy. There are still some things that can be done to make sure that the computer is as secure as it possibly can be, but overall, there are not very many options. If a person has never dealt with any kind of security issue, it is possible that they will not be able to tell much of a difference between the two, but other people will feel the need to make an investment in the appropriate choice.

If it appears that Advanced SystemCare has a number of drawbacks, there is a rationale behind why it is ranked fourth on this list despite the fact that it is deserving of a spot on it. It comes with a good uninstaller that does more than just hide unnecessary software and plug-ins on your computer. If you have the ability to uninstall everything in its entirety, you will never have to worry about those issues again.

#5 CCleaner

In spite of the fact that it is ranked fifth on the list, CCleaner is not a terrible choice by any stretch of the imagination. There are a great number of people who find that the cleaner is the most effective way to clean, and there is a good reason why it is one of the most popular sellers. In contrast to the other options on this list, there is a version of the software that is compatible with both PCs and Macs. The demand for cleaning tools among Mac users is typically lower, but the availability of those tools is a benefit nonetheless.

The best of their utilities are helpful when it comes to managing cookies, history, and privacy in general. People have a sense of security when they have CCleaner running because it is relatively simple to delete anything that might result in complications in the future. It is possible to set up automatic cleanings on a predetermined schedule, which is helpful for people who have a lot on their plate and do not want to be bothered with running everything during peak times.

CCleaner provides real-time monitoring at all times, which is yet another important feature that it offers. CCleaner will have the ability to determine whether or not something that occurs in the middle of the day requires attention. It is convenient to have something that operates in real time, as this allows for timely updates to be provided while also enabling people to go about their day without the sensation that anything is holding them back.

When it comes to licencing, CCleaner has a few different issues, which, in the end, makes it a little more expensive for people who are dealing with a large number of different computers at the same time. While for some people this will not be much of an issue, for others it will be one of the most frustrating things that they have ever dealt with.

Do not be afraid to give CCleaner’s free trial a shot and see what it has to offer you and your computer. Although there are other options that are more comprehensive and beneficial in a variety of ways, CCleaner has consistently ranked near the top of these types of rankings for some time.

Final thoughts on PC Cleaner tools in 2021

In the year 2021, there are some people who believe they can get by without using cleaner tools; however, these tools are still very important. Although Windows 10 comes with a number of built-in utilities that are helpful to a certain extent, the five options that have been listed above are all excellent choices that will provide an even more thorough cleaning in general.

There have been many attempts made to compete with iolo System Mechanic, but it has managed to maintain its position as the industry leader despite these challenges. This company is the only one that provides all of these tools in one convenient package. There is a plethora of justification for making the investment, as well as trusting in what it offers.

The overall investment is a small price to pay for problems that could hurt productivity or even force a person to feel as though they need to buy a brand new computer. These problems are easily avoidable. Extending the amount of time a computer can be used for can save a person hundreds of dollars, which is ideal for the many people who use computers for their jobs, their education, or their personal enjoyment. Even though not all PC Cleaner Tools live up to their claims, it is possible to demonstrate that using only the very best of them is worthwhile.
