Top PC Optimizers of 2020 (Tested in May)

Our monthly results are usually posted within the first week of each month. However, we expect the rankings to remain steady for the next while. Regardless, if there's any changes coming, we'll give you early warning. Thanks to the entire team for their help - and to the generous community for your reports and suggestions.

This is the best PC optimization software (after our May 2020 tests) for superior computer and Internet speed. Plus, it maintained actually improved stability - unlike many of the other tune-up utilities that slowed performance and crashed our PCs.

2020 Best PC Optimizer Software for Windows 10, 8, and 7

We tested and compared all of the best computer optimization software available to speed up and repair your Windows system. After over 100 hours of testing 32 of the most popular optimizers, here are the best PC optimizer results.

1. Wise Care 365 Pro:

99% Wise Care 365 Our recommended choice if you're looking for the most advanced system optimizer available for your Windows computer and Internet. WiseCare 365 Pro boosted our speed the most, while maintaining actually improving stability.

Also absolves your system of all problems and even prevents any future ones from developing.

The best speed results, best tuneup utilities for repair, and improved stability. It's easy to see why this is the leader in our recent test. It will automatically optimize your system in mere minutes. It's perfectly safe and even improved stability in our major error test. Since it was the only one that did that, was an amazing feat in itself.

After our latest tests, our entire team concluded there's simply none better than Wise care 365 Pro right now or in the foreseeable future - and here's why ...

Reasons why this is the best of 2020;
  • Best Speed Results of all tested. Computer responsiveness improved with lightning quick program and game loads.
  • The advanced RAM optimizer put a stop to the slowdowns we had during intense usage of resources. Whether from demanding games or resource-intensive programs.
  • Boosts the Internet response rate up to 300%. Will also optimize the most popular web browsers for extreme surfing speed. Solves disconnect issues.
  • Repaired all Windows errors and system problems on our error-plagued test rig. Improved our Windows install like it was back to new.
  • Passed over 50 malware scan checks. Our anti-virus was set to the most sensitive heuristic setting. It has never alerted us about Wise Care 365 Pro.
  • Effective on all Windows 10, 8, 7, Vista, and even old XP. Works with all old or new desktops and laptops running any of those operating systems.

Unlike all others tested, Wise Care 365's continual and constant slowdown prevention, lets you keep your speed gains. Your PC and Internet will always be at the highest speed possible, each and every day, from now on. Wise Care 365 Pro gets our strongest recommendation.

WC 365 Pro proved itself in every PC / Internet speed, system repair, and stability test we threw at it. The end result - super speed levels without errors or problems.

2. Iolo System Mechanic Pro:

95% System Mechanic Pro. One of the best system utilities to easily fix PC problems, System Mechanic Pro provided a thorough cleaning and fixed the majority of errors on our troubled Windows' test computers.

A thorough and complete repair utility that is a pleasure to use. Although the top pick in our PC optimizer list also has excellent repair, but with much more comprehensive optimization.

3. Iobit Advanced SystemCare:

91% Advanced SystemCare Ultimate Box and Screenshot.Both versions of Advanced SystemCare (Pro and Ultimate) give you excellent system tune up utilities for Windows computers. When your PC is struggling, ASC has good problem solving capabilities to fix it up.

Years ago, this was my go-to computer optimizer. As time went by, I found others that were much more effective, but I still have a soft spot for this one.

4. aShampoo WinOptimizer Pro:

91% WinOptimizer Box and Screenshot.With the WinOptimizer program, you will get faster speed for your Windows PC through one of the easiest to use interfaces.

A good option for new computer users that want lightweight optimization from an extremely simple PC optimizer.

However, the top 2 are also easy to use but much more effective with their advanced automatic optimization.

5. Glary Utilities Pro:

90% Glary Utilities Box and Screenshot. A great set of Windows tuneup tools that provides a quick PC tune up. Unfortunately, Glary Utilities lacks more than a few of the advanced optimization features of the leading optimizers.

However, it still does an excellent job to keep your PC stable with a mild performance boost. The multitude of manual settings were fun to explore, but very time consuming, and there's a fairly high learning curve.

6. Advanced System Optimizer:

88% Advanced System Optimizer.A simple program to use, Advanced System Optimizer has decent computer optimization routines that will clean up Windows for a slight PC speed improvement, but not to the level of the top performance software.

However, there's no dedicated network module, so if that's important, you may want to see which optimization software has the best Internet optimizer for Windows.

7. AVG PC Tuneup:

88% AVG Tuneup Screenshot. AVG's Windows tuning utility, claims to make old PCs live longer and new PCs run faster. Did a fine job for what it offered, a mild tuning combined with a thorough Windows maintenance cleaning.

If you need a quick PC tune-up, it performed reasonably well, but there are other optimization programs above that will certainly serve you better.

8. Symantec Norton Utilities:

88% Norton Utilities. In the late 1990's, I used Norton Utilities and loved it. There were very few competing programs at that time. And it was the best utility software available, but that was over 20 years ago.

Today, it's still a fair option to clean your hard drive of junk files. It does lack the advanced system optimization tools of the better solutions.

9. Piriform CCleaner Pro:

85% CCleaner Pro. Had trouble recently with malicious code injected into their program. At last check, it appears they have the all clear now

It's more of a cleaner than an optimizer. An advanced Windows speed optimizer is not CCleaner's strength. Like most, you can set a schedule to clean your system, but it had a very weak optimization score.

10. Slimware SlimCleaner Pro:

84% SlimCleaner Pro. An array of system maintenance utilities to keep your computer clean. Also helps to remove unwanted programs.

A pretty and colorful program that can struggle at times to optimize. In the end, performance was disappointing. Yet the interface was one of the simplest and easiest to use.

The Runner-Ups:

After testing, comparing, and reviewing to find this year's best PC optimizer, there were a few contenders that never quite made it to the top, but they were still good programs in their own right. Some of the bottom dwellers are certainly not worth listing here or anywhere - mostly for your protection, as a few of them were very harmful.

Comodo PC Tuneup - Was a little shallow in features. While a decent PC cleaner, it fell back with the lack of advanced optimization we have come to expect from today's more popular optimizer programs.

Anvisoft Cloud System Booster - As always, these cloud solutions sound good on paper, but the reality is the results were worse than standard pre-programmed solutions.

Jv16 PowerTools Pro - Includes a very detailed registry cleaner that performs really well, but it lacks the app's and tools needed to push your system to much faster speeds.

Defencebyte Computer Optimizer - We almost missed this one. It performed well enough, but it will need to provide a little more advanced optimization to satisfy speed hungry Windows' users.

Asmwsoft PC Optimizer - Optimizes PC's from within a very simple interface, but it needs more features.

Pointstone System Cleaner - A junk file cleaner for Windows, it does a fine job of removing useless files and data from your computer. Needs more advanced features to become a leading solution.

1-Click PC Care - The single click sounded good up front, but the overall performance was only fair.

Amigabit PowerBooster - With just OK results, it seems that PowerBooster is becoming one of those programs that is not being improved upon over the last few years.

WinUtilities Pro - WinUtilities Pro cleans your computer and can fix problems with a single click. More of a PC cleaner than a pure speed focused optimization program.

BoostSpeed - So many hoops to jump through to get the program, but not worth it in the end.

Other software considered for our tests, but in the end did not meet our optimizing criteria included; Bleachbit, itl Windows Optimizer, Malwarebytes, Revo Uninstaller, and IObit Uninstaller.

Full Review of the Best PC Optimizer

Our 2020 Editor's Choice Award for best PC optimizer went to Wise Care 365. We put it through the paces during our long term tests, and we're still using it months later.

Wise Care 365 Pro Review

In-Depth Analysis (after 2 months)

A serious speed-eccentric optimizer that surpasses other higher priced but less effective optimizers. Sure, the interface may need a little work, as it's a little bland, but the speed results and value easily make up for an interface that you will rarely see. With the mostly set it and forget it advanced optimization routines, you will simply be enjoying the added zippiness to your PC and Internet - instead of poking and prodding through the program like many of the other overly complicated, and less effective optimizers available online. If you invest in WC 365 Pro, it will reward you with faster performance and a much more stable Windows environment to avoid any problems for the lifetime of your PC.

Why did it win BEST PC Speed Optimizer?

Computer optimizer working on a laptopContinually and effectively optimizes your PC and Internet. The automatic option will keep your system in a perfectly optimized state.The full system optimizer improves startups, shutdowns, and more responsive performance for your PC and every program installed. You can easily set the real-time optimization to work on the fly to safely adjust system services and RAM.

Why did it also win the Best Value PC Optimization Software?

Quite frankly, I believe it's priced too low for all of the advanced PC optimization features included. Hopefully, the developers will continue to offer it at this low price, but I can't help but think they may eventually raise the price to the same level as the less effective optimizers in the $40-$90 range.

Wise Care 365 showing all of the tuneup utilities includedEven though WiseCare's interface is not as graphically pretty as a few others, I believe it's intentional to make it easier to quickly learn the program.

As you can see in the image, it still looks cool and better than most. Plus they keep improving the interface and fine tune the program with each update - the latest being just a few weeks ago.

An easy and automatic Windows optimizer

You can quickly set-up the auto-optimization to have the program fully optimize your system continually. This is what I did to safely squeeze even more speed out of my PC and Internet every time I used it.

After a week, the improvements were even more pronounced - and after months of use, this full scale system optimizer has made all our test computers the fastest they've ever been. Including perfect stability - no crashes, freezes, or even minor slowdowns for months. Let's take a closer look at how it performed.

Long term performance results after 2 months

We thought it would be important to continue testing through 60 days - which is how long the satisfaction guarantee is valid.

  • The system speed (PC and Internet) on every computer tested has not returned to former slow speeds - they improved even more over 2 months.

    Many of the other optimizers did not keep their speed gains and slowed down more over time.
  • Perfect stability has been maintained. Not a single error or problem on all systems. Even our old Windows 7 notebook is still working perfectly.
  • Wise Care 365 Pro worked seamlessly with every program. Had perfect compatibility with all, including a multitude of security and anti-virus apps.
  • All Windows versions are perfectly stable two months later. Even after a few major Windows updates, there were no changes to the performance.

Also has a very detailed, and more importantly, safe registry cleaner with a built-in undo function. Since so many other weaker programs are fairly close in price, it's easy to recommend getting WC 365 Pro for it's comprehensive PC optimization and slowdown protection. It also worked alongside all of our current background stability test programs without any problems - while many others, that cost more, failed miserably.

All games installed had their frame rates and loading times improved significantly - sometimes as high as an additional 20 FPS, and routinely knocked off 5-20 seconds to load times for games, including League of Legends, Fortnite, PUBG, Overwatch, Siege, CoD, and even Star Citizen - an unfinished early access title. I also felt much less frustration while playing with smoother frame rates - as there were no longer any of those annoying occasional freezes and slowdowns I had previously from my un-optimized system.

When you consider this program is saving you time with every task you perform on your computer, that can add up to hours every day - especially if you're like me and work on your PC for long sessions or play games late into the night.

After our latest tests, our entire team concluded there's simply none better than WiseCare 365 Pro right now or in the foreseeable future - and here's why ...

Features and Benefits

  • Best Speed Results of all 32 tested - Overall computer responsiveness improved dramatically with lightning quick program and game loads.
  • The extremely advanced RAM optimizer put a stop to the slowdowns we had during intense usage of resources from demanding games and programs.
  • Boosts the Internet response rate up to 300%, and will fully optimize the most popular web browsers for extreme surfing speed.
  • Dramatically reduced the video buffering problems I was having while watching Netflix and YouTube.
  • SSD optimization for full speed on digital drives. On hard disk drives, it will intelligently place important data to the high speed sweet spot of your drive.
  • Instant success with the automatic settings - so easy to initiate. After a few seconds of setting it up, the program does all of the work to optimize.
  • Prevents slowdown from creeping back. This is important because many PC optimizers rely far too much on user interaction to solve future problems.
  • You can create a portable version - or you can fully install for a more thorough integration - I recommend a full install for the automatic settings.
  • Gamers will have a field day with the additional performance for better frame rates and reduced lag during online gaming.
  • Repaired all Windows errors and system problems on our intentionally plagued test rig. Reset our Windows install like it was back to new.

PC optimization software is a collection of tuneup utilities programmed to improve slow computer performance by optimizing settings within the Windows operating system. This removes the speed-reducing default bottlenecks that are put in place for easier hardware compatibility for the PC manufacturers. Once optimized, all of the computer's hardware components - including the CPU, GPU, and RAM - will be able to utilize their full capacity, leading to improved performance.

All of the optimizers on this page were the best in our tests. If I was to recommend one optimizer for everyone, from experts to new users - My best PC optimizer choice is absolutely Wise Care 365 Pro.

The reasons why are outlined in detail on this page. Simply put, it's the best because there's just no other program that can compete with its' advanced PC optimization features for the fastest speed gains, perfect repairs, and rock-solid stability.

Why do some other tech sites have a different opinion?

For over 20 years, I've been testing and personally using tuneup utilities while also writing my opinions of them on this site and a few others. One thing that has been constant is the multitude of emails I get from many of the software companies offering kickbacks and extraordinarily high commission rates to feature their software.

Since I've had a rewarding career as a programmer, I have been fortunate enough (through hard work) to be financially secure - now I'm happily semi-retired. So these offers don't have an affect on me, like they would on a tech site with a business bottom-line. Most importantly, I have never received one of these emails from WiseCare - and they've been around for over 10 years - that may explain the lack of enthusiasm on other tech sites. I commend the Wise Care team for focusing on the quality of their program and not becoming obsessed with marketing hype like most others. It's an intelligent strategy that I feel will help them win their due accolades in the end.

Of course, many other tech site may not have tested the new 2020 advancements to Wise Care 365, or they haven't updated their lists in a long time. By the way, many tech sites just change a few words or the actual published date to look like they ran new tests and updated for the year - don't be fooled, some of those lists are ancient.


Every computer user needs their system to be the best it can be - and an optimizer will produce a super fast and perfectly performing computer for as long as you own your PC. And it works with any desktop, notebook, or tablet running Windows.

You'll get faster boot-ups, program launches, better web page delivery, improved download speeds, and an overall improved responsiveness to everything you do on your computer. This also includes anything you do online, since your Internet settings and web browser will be optimized as well.

All of the optimizers on this page were the best in our tests. If I was to recommend one optimizer for everyone, from experts to new users, my top choice is absolutely Wise Care 365 Pro. There's just no other program that can compete with its' advanced optimization features.

If you decide to get an optimizer elsewhere, please be careful. There are more than a few optimizers with hidden malware and malicious code. All listed here on our web site have been fully scanned and proven to be safe and effective. Thanks for reading.
