Best PC Optimizer 2021 (Tested in July)

To be the best PC optimizer, the program must tune up your Windows PC and Internet speed to the highest levels possible without any errors or system instability.

This is the best PC optimization software (after our July 2021 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.

A serious speed-eccentric optimizer that surpasses other higher priced but less effective optimizers.

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.

Why did it win BEST PC Speed Optimizer?

Optimizing a Laptop PCContinually 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 other quality optimizers in the $50-$80 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 to the right, 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

The automatic optimization of your PC is easily accomplished in the program. Even though the interface is not as graphically pretty as many others, I believe it's intentional to make it easier to quickly learn the program.

You can quickly set-up the auto-schedule to have the program fully optimize your system continually. This is what I did and it safely squeezed 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 my PC the fastest its' ever been. Including perfect stability - no crashes, freezes, or even minor slowdowns for months.

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.
  • 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, CyberPunk, New World (Beta), 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 ...

The top reasons why this is the best PC optimizer software...

  • Best Speed Results of all tested - Overall computer responsiveness improved dramatically with lightning quick program and game loads.
  • The 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.
  • 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.
  • 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. 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.
  • 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.

System Optimizer for Quick Repair:

System Mechanic Pro

"Fixes and perfectly stabilizes your PC with a quick fix and repair module, but be aware that WC 365 Pro (above) does a better job at repair, plus it improves speed."

System Mechanic Pro. Looking for a premium PC optimizer that delivers state of the art repair and speed improvements in minutes? Not only is this one of the most comprehensive system cleaners we have used, it also has one of the fastest scan speeds. It will fix a problematic computer that has slowed down significantly or is showing signs of trouble.

Computer Optimizer with Security:

Advanced SystemCare Ultimate

"An inexpensive software suite that includes security protection and system utilities. Although the top optimizer (WC 365 Pro above) will also secure your computer and Internet while giving you much better PC and Internet speed increases"

Advanced SystemCare Ultimate. If you're in need of anti-virus protection, Advanced SystemCare Ultimate can scan your system for malware and tune it up at the same time. While the security protection is not really any better than the free protection provided within Windows (Defender), it provides a clearer interface. The optimization features lack results compared to others we tested. If you're on a budget, but still need a good system utilities suite, ASC Ultimate should be considered.

Windows Optimizer for Beginners:

WinOptimizer Pro

"A simple and easy to use computer optimizer. Great for novice users. However, most of these programs are easy to use, so I would not feel intimidated into getting the easiest one. The thrilling speed increases of WC 365 above, are easy to achieve."

WinOptimizer. Give me easy PC optimization. WinOptimizer was awarded the Easiest-to-use Windows Optimizer. If you're a beginner computer user and don't want to learn a more sophisticated program, you may want to consider this optimizer. However, If you're only going to be satisfied with the best for speed, then you will want to consider the top-rated optimizer, Wise Care 365 Pro over WinOptimizer.

"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. System Mechanic Pro

PC Tuneup and Windows Repair Utilities

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. WinOptimizer Pro

Easy PC Booster for Beginners

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.

4. Advanced SystemCare Ultimate

Computer Optimizer and System Applications

91% Advanced SystemCare Ultimate Box and ScreenshotBoth 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.

5. Glary Utilities Pro

Registry Cleaner and Tools

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. AVG Tuneup Utilities

Windows Cleaner and Maintenance App

89% 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.

7. Advanced System Optimizer

Performance Software and PC Cleaner

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 Internet optimizer, so if that's important, you may want to choose another option. For us, since everything is connected to the Internet today, so that was a deal-breaker.

8. Slimware SlimCleaner Pro

Clean Up Windows Software

87% 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 properly. In the end, performance was disappointing, but the interface was one of the simplest and easiest to use.


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.

Norton Utilities - A good option to clean your hard drive of junk files, but it lacks the advanced system optimization tools of the better solutions.

CCleaner Pro - A basic PC cleaning utility. Unfortunately, it lacks the more advanced optimization of the better downloads on our list.

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, Revo Uninstaller, and IObit Uninstaller.

What exactly is PC optimization software?

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.

The results of the optimization lead to fine-tuning your PC and corresponding programs to provide blazing fast speed gains - while improving system stability. Perfect PC optimization is only possible with the more advanced PC optimizer software - such as listed on this page.

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 fully optimized as well.

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. Good for them - to focus on the quality of their program and not become 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 2021 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.

Final Word

Optimizing your PC can be complicated if you're into manually adjusting hundreds of settings and registry entries. Even a tech expert would never be able to manually adjust all of the hidden and locked settings within your computer.

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

If you decide to download a PC optimizer elsewhere, please be careful. There are more than a few 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.
