2021 Best PC Optimizer | Fastest Speed Up Results 2021

Jan 14 2021

A PC optimizer is speed up software created to improve slow computer performance by optimizing a Windows laptop or desktop PC system.

The best PC optimizer in our test, generated the fastest speed results on all our Windows 10 (and older) computers. If you want to speed up your PC, this is how...

Best PC Optimizer for Windows

"After over 100 hours of testing 32 of the most popular PC optimizer software, only one proved far superior for speed, stability and repair."

What is the Best PC Speed Up Software?

To be considered the best PC optimizer, it must speed up your computer and Internet speed to the fastest levels possible without any errors or system instability.

Our January 2021 tests showed the top PC optimizer was far superior to all others. It was able to significantly improve overall performance. Both PC and Internet speed.

Plus it maintained, actually improved stability - unlike many of the other Windows tune-up utilities that slowed performance and crashed our PCs.

The Best PC Optimizer of 2021

Wise Care 365 Professional

"Includes excellent optimization with an added benefit of real-time code protection. Prevents any slowdown and provides continual PC and Internet optimization. Just updated, this is the new highly advanced version for 2021."

Editor's Choice:

"Best PC Optimizer for less than many other bloated optimizers that are far less effective... accelerates your PC to extreme speeds with improved stability."

Basic Version.WiseCare 365 Pro contains the most PC optimizer software benefits and automatically delivers speed.

PLUS WC 365 Pro has even more advanced features to continually keep your PC and Internet at maximum speed. While also providing rock-solid Windows' stability with advanced slowdown protection.

Wise Care 365 Pro delivers on its' promise of optimizing your PC and Internet. Compared to all others, it provided a lot more optimization and increased stability.

( EDIT: The last few weeks, the PRO version was on sale, but it's ending soon. )

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 the Pro version, it will reward you with faster performance and a much more stable Windows environment to avoid any problems for the lifetime of your PC.

Optimizes PC and Internet Speed

Optimizing a Laptop PC.Continually 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.

How much does a PC optimizer normally cost?

Quality PC optimizers are usually priced in the $50-$80 range. However, Wise Care 365 is frequently on sale, bringing it down to a much lower cost. Quite frankly, we believe it's priced too low - even at retail - for all of the advanced PC optimization features included. Hopefully, the developers will continue to offer it at this low price, but we can't help but think they may eventually raise the price. Especially since the quality of the product has improved dramatically over the year's while the price has remained stationary.

Wise Care 365 showing all of the tuneup utilities included.Even though WiseCare's interface is not as graphically pretty as a few others, we 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.

PC optimization performance after 2 months

In our comparison of PC optimization software, we were able to determine WC 365 Pro was the best PC speed booster available. While we initially planned to test for just a few hours, it turned into a 2 month journey with over 100 hours of testing. Simply because we wanted to see the long term affects on PC performance. Here's what we found.

  • The system speed (PC and Internet) on every computer tested has not returned to former slow speeds. In fact, they improved even more over 2 months.
  • Perfect stability has maintained. Not a single error or problem on all systems. Even our old Windows 7 notebook is still running perfect at the much faster optimized speed.
  • Wise Care 365 Pro works seamless with every program. Had perfect compatibility with all, including a multitude of security and anti-virus app's.
  • All Windows versions are much faster and in perfect running order 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. You have complete control to clean away unwanted software bloat, and other never-used junk file data. The descriptive help features makes it easy to understand what the program is doing every step of the way - so mistakes are near impossible. But there's a great rewind feature if you find yourself straying off course.

Does Wise Care 365 Pro Have the Best PC Optimizer Features?

PC Optimizer Features

We tried to highlight the best features of Wise Care 365 Pro, but there are so many, we ran out of room. This is an extensive program with the best PC optimizer features a mere click away. Also has an option for continuous automatic optimization.

Of course, we love its' comprehensive PC optimization and slowdown protection. But it also worked alongside all our current stability test programs without problems. While many others, that cost more, failed in a miserable and disappointing way.

We couldn't help but want to test out these system improvements on our gaming focused computer. It was no surprise that it is the best game optimizer for PC. All games installed had their frame rates and loading times improved. Sometimes as high as an extra 20 FPS. Plus it was routine to knock 5-20 seconds off our load times for games.

This included Cyberpunk 2077, Assassin's Creed Valhalla - Odyssey - Origins, Microsoft Flight Simulator, League of Legends, Fortnite, PUBG, Overwatch, Siege, CoD, and Star Citizen. A blessing for early access games that lack the performance optimizations of finished games.

We also felt much less frustration while playing with smoother frame rates. There were no longer any of those annoying occasional freezes and slowdowns.

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.

PRO's

  • Real results; the best system speed (PC + Internet), comprehensive repair, with rock-solid stability.
  • Improved PC performance on every program and game installed on our systems.
  • Boosted the Internet much more than all others. This helped improve movie streaming with much less buffering for perfect playback. File download speeds also improved.
  • Setting up the automatic function was easy and very effective. It made fumbling around the program unnecessary.
  • The accumulative and continual optimization improves performance even further as time goes by. We got outstanding results immediately.
  • After 2 months, it's still optimizing and making performance better.
  • There's an optional portable version included for free with the Pro version. Although the full install includes a few more advanced features.
  • Future-proof because it works with any Windows laptop or desktop, new or old. You'll be able to use it on all your computers in the future.
  • Passed all online malware scans. 100% clean.
  • Passionate developers who care about their work with frequent updates and friendly support.
  • No-risk and no-hassle 60-day money-back guarantee.

CON's

  • The portable version (included for free in the Pro version) does not contain a few features. For complete optimization and security, we recommend a full install (default).
  • Interface is a little bland and not as modern as others. Rarely seen since we used automatic functions and the convenient right-click context menu's.

Our Recommendation

The answer is clear. Wise Care 365 Pro gets our full recommendation as the best PC optimizer of 2021. You'll get innovative technology that is easy to use. It will unlock the major optimizing opportunities that lay dormant on every computer. If you're tired of the default settings that are in place to keep the PC manufacturers' job easier. It's time to access the true power of your computer system.

It's the surefire way to boost your computer speed while improving stability. WC 365 Pro propels itself into the top PC optimizer slot for 2021.

Recommended for: Users looking for extreme PC and Internet speed. We highly recommend the Pro version of WC 365 for anyone who's serious about getting the most out of their PC and Internet, each and every day. Versus all of the others we tested, and we ran all of them for over 100 hours, you'll get a lot more with WC 365 Pro than any other.

It's certainly affordable compared to many other popular choices that are less effective. We believe it's actually under priced - especially if you're lucky enough to catch WC 365 Pro on sale. We routinely check for the lowest sale price and always post it in our latest sale update here. Enjoy.

Works with: All old or new PC Desktops, Notebooks, Laptops & Tablets running...
Microsoft® Windows 10. 8, 7.

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.

Runner-up PC Optimizers

The leader above was well ahead of the pack as the best PC and Internet optimizer. Here's the rest of the pack, that never quite made it to the top, but they're still great programs in their own right.

2. 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. 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 optimizers available.

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 Pro

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 our go-to computer optimizer. As time went by, we found others that were much more effective, but we still have a soft spot for this one.

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.

Our PC Optimizer Testing Procedure

We recently ran through the entire gamut of the best PC optimizer downloads online. We compared and tested all of them with our focus primarily on the following:

  • Measured overall speed improvements including; operating system, drives, CPU, GPU, RAM, and Internet
  • Effectiveness of PC repair. It must fix Windows problems safely.
  • Windows registry cleaning. Reduced registry size without corruption.
  • Slowdown protection. Including the ability to prevent future problems.

  • Remove needless programs and services (bloat) to improve startup.
  • Improved gaming performance. Comparing fps at default vs optimized.
  • Easy and automatic. No complications to lead users into trouble.

That's the primary focus, but we did evaluate over 20 more variables that were less important. These smaller factors were grouped together so as to not dilute or enhance the scores with less significant considerations.

Please note: Our scoring system displays the final score out of 100 percentile (%). The individual category ratings are graded from A+ (Excellent) to F (Very Poor). We did this because there were some quite dramatic fluctuations on various test systems with some of the programs. By grading, it allowed us to add our experience and expertise to slightly adjust a few of the category grades based on instability and other factors. However, only a few were slightly adjusted and they were very low on our list of the 32 tested.

Common Questions

What is the best free optimizer for Windows 10?

If there really was a free PC optimizer, it would be here. But there are only free scans (more registry bloat) that do nothing. We believe it's not worth downloading free PC optimizers because some intentionally slow or lock your PC to force you to buy their junk ransomware - just to get back to normal speed.

Unfortunately, these nasty free programs make many people ask, are PC optimizers a scam? So many PC users lose out on optimizing their computers just because of the bad reputation of the free spyware peddlers.

What is the best speed up software to buy for Windows 10?

Choosing which PC optimizer to buy can be a little confusing since many programs do a poor job of explaining exactly what they're going to do. We ran extensive tests on our Windows 10 computers and if you want to buy the best software to speed up PC, get Wise Care 365 Pro. It's a safe and effective solution created by professional programmers that care about their product and you, their customer. Includes friendly support and a 60 day no-hassle full refund guarantee.

Conclusion

All of the optimizers on this page were the best in our tests. Of course, in the end, there can only be one that is above all others after testing. Our best PC optimizer choice for 2021 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.

All of the optimizers on this page were the best in our tests. They're easy to install and setup. Plus they have a very friendly software uninstall process that cleans up after themselves - unlike most of the rogue free optimizer downloads.

Research and Opinions

Best PC Optimizer for Windows

Using PC optimization software has made Windows 10 faster and perfectly stable.

For over 20 years, We've been testing, personally using, and setting up tuneup utilities for Windows while also writing our opinions of them on this site and a few others.

There have been ups and downs to these software downloads over time. For years, some registry cleaners were giving all PC optimization software a bad name from exaggerating how many errors they were finding in their dreadful free scans. Those days are not quite over yet, as there are still many junk optimizers with false claims and amateur coded programs that are more dangerous than helpful.

Another thing to look out for. Companies that sell software are beginning to write blogs that review products. Yeah, you heard that right. They make web pages with a list of products and rate them - of course placing their product at the top. Would you consider that a fair and unbiased opinion? It's a shame these practices continue to be rewarded. To find this, you can usually just remove the blog from the URL to see the actual site.

Software Review Practices

It's difficult for a consumer looking for the best software for their PC, to encounter these types of practices that throw all credibility out the window.

How Computers Slow Down and the Solution

Let's take a quick look at what causes a computer to slowdown in the first place. As shown in the image below, a PC optimizer can repair problems and improve speed back to normal - AND by utilizing the advanced optimizations, you can go beyond normal speed to the safest limit. For further speed increases, you would need to perform dangerous overclocking, but we don't recommend that, as it can lead to electro migration (interconnect failure) within your hardware components.

A Graphical Explanation of Computer Slowdown

This image gives you a keener understanding of why a computer slows down from everyday use. Even a brand new PC will need to be optimized eventually.

To safely increase computer speed without going into the overclocking danger zone, the best solution is high performance PC optimizer software. Of course, another option would be to upgrade expensive hardware components or an all-out new PC, but that's not why we're here. We're trying to get the most out of our current computer.

If we were to recommend one optimizer for everyone, from experts to new users, our top choice is absolutely WiseCare 365 - and we much prefer the Pro version. There's just no other program that can compete with its' advanced optimization features.

We 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 we feel will help them win their due accolades in the end.

Final Word

What will a PC optimizer do for your system? 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.

Safe and Effective

We only list safe PC optimizers that have been proven effective. However, while browsing online, you may encounter very tempting offers to download free optimizers. You should be cautious using this type of software, as there are malicious free optimizer downloads that contain unwanted malware that have the potential to seriously harm your computer. Many are labeled by anti-virus programs as PUP or Potentially Unwanted Programs.

In conclusion, the new 2021 advancements to Wise Care 365 are a major leap forward for PC optimization software. If you decide to get an optimizer elsewhere, please be careful.

Thanks for reading.
