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

Basic VersionPlease Note: WiseCare 365 Pro (above) contains the most PC optimization benefits and automatically delivers speed - shown to the right..

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.

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.

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 optimization 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 shown 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.

Easy and Automatic Optimization for Windows

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, 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.

📈 Best Windows Optimizer Software for 2020-2021

Microsoft Windows® 10. 8, 7, Vista, and XP

2. System Mechanic Pro

PC Tuneup and Windows Repair Utilities

95% System Mechanic Pro Contains some 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.

Although the top pick in our list (WC 365 Pro above) also has excellent repair, but with much more comprehensive optimization for your PC and Internet.

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 Windows optimizer (but not the best) for new computer users that want lightweight optimization from an extremely simple PC optimizer. The top 2 are also easy to use but much more effective with their advanced automatic optimization.

4. Glary Utilities Pro

Registry Cleaner and Tools

Glary Utilities Box and Screenshot 90% A good Windows system utility that provides a modest PC tune up. Glary Utilities does lack numerous advanced optimization features of the leading optimizer above.

It does an adequate job to keep your PC stable with just a slight performance boost.

A Few 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.

5. Advanced System Optimizer

PC Optimization Software

Advanced System Optimizer A simple program to use, Advanced System Optimizer's computer optimization routines will speed up your PC. It has a very impressive automatic function and we really like the pleasant, yet colorful interface.

However, there's no dedicated Internet optimizer module, so if that's important, you may want to choose another option. For us, since everything is connected to the Internet today, that was a deal-breaker. But if you're looking for just strictly PC optimization, it certainly deserves consideration.

6. AVG Tuneup Utilities

Windows Cleaner and Maintenance App

AVG Tuneup Screenshot Is AVG's PC Tuneup Safe? We had no problems using AVG PC Tuneup. However, you'll need to be careful and read what each of the 35 included tools are doing before proceeding. It was a little too easy to make mistakes.

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. Symantec Norton Utilities

PC Tools and Utility Program

Norton Utilities In the late 1990's, I used Norton Utilities and loved it. There were not many competing programs at that time and it was easily the best utility software available.

Today, it's still a good option to clean your hard drive of junk files, but it lacks the advanced system optimization tools of the better solutions to improve slow PC speed.

8. Piriform CCleaner Pro

PC Cleaner Software

CCleaner Pro Had trouble recently with malicious code being injected into their program, but it seems to have been cleared up.

It's more of a cleaner than an optimizer. If you're looking for an advanced Windows speed optimizer, that's not really CCleaner's strength. You can also set a schedule to clean your system, but it had a very weak optimization score.

9. Advanced SystemCare

Computer Optimizer and System Applications

Advanced SystemCare Ultimate Box and ScreenshotBoth versions of Advanced SystemCare (Pro and Ultimate) give you average system tune-up utilities with good Windows problem solving capabilities.

The Ultimate version also includes a good but not leading-edge anti-virus and anti-spyware. This is a heavily marketed and hyped program, but it falls well short of the leaders.

10. Slimware SlimCleaner Pro

Clean Up Windows Software

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.
