To help you out for the new year ahead, we have compiled a list of some of the top free PC optimizers that will get your computer ready for 2021! No security risks, only legit software meant to help you out in optimizing your computer’s performance.


1. Razer Cortex




  • Free to use
  • Great customization
  • Optimization per software
  • Focus on gaming rigs
  • Doesn’t fix errors


Razer Cortex is a fantastic optimization program for gamers, and may even help you in other situations. It includes features such as Game Booster, which stops unnecessary background processes to speed up your computer.


The System Booster tool is a perfect way to optimize your computer and make sure it's running at maximum efficiency. It cleans out old files, speeds up the process by changing network settings or disabling unused Windows services (which can affect performance), as well as defragments disk caches used for gaming purposes.


You can get all this in one, easy-to-use free application!


2. CCleaner




  • Lightweight
  • Free to use
  • Many optimization features
  • Offers error-solving solutions
  • Some features are paid only
  • Bundled software during installation
  • Constant reminders to switch to the paid version


CCleaner is one of the best known optimization apps for Windows, and for a reason. The software has been around for many years, and has only improved as time goes on. It’s on the top of our list with features like Registry cleanup, browser-focused cleanup, and much more.


The interface of CCleaner is clean and simple to use. Every module has its own functions located in a logical order, so you'll never get lost or confused looking at them! This makes things easy for the user, even beginners. This makes CCleaner intuitive; your computer will start outperforming your expectations within seconds.


One more point regarding functionality — there are some features locked behind a paywall. If you’re not planning on paying for full functionality, you won’t have access to select features that could improve your PC’s performance.


3. Iolo System Mechanic




  • Great performance-enhancing tools
  • Addresses common PC problems
  • Provides additional tools
  • Some features are outdated
  • The internet booster doesn’t live up to expectations
  • Free trial is time-limited


An all-in-one suite, Iolo provides its users with top of the line features that can get your system in shape with a single click. If you’re sick of sluggish performance, trying Iolo — and maybe even purchasing the full version, — will improve your experience in all fields.


What we love about Iolo is the extra tools included, such as the internet booster. The software really targets every important part of your system to ensure it’s fully upgraded to get the most out of your resources. It even introduces solutions and explanations to common computer issues to teach you what to look out for and how to avoid them in the future.


For many, Iolo System Mechanic is the only PC tune-up utility they'll ever need. Unlike other programs on the market that require you to purchase multiple licenses, Iolo can be installed onto an unlimited number of machines with a single license!


4. AVG TuneUp for PC




  • Vast optimization features
  • Comes with additional tools for driver updates
  • Adds a secure file-shredder
  • Some features are locked behind the premium version
  • Doesn’t come with unlimited licenses


AVG TuneUp for PC is one of the most versatile optimization tools on this list. It’s specifically designed to work on PC’s running Windows, and it features a one-click solution for all your PC maintenance. TuneUp scans your PC in seconds, identifying performance issues that you can fix with just one click.


With this free PC optimizer, you can remove junk files, optimize startup programs to boost faster, and even update outdated drivers! There's no reason not to give it a try when looking to improve PC performance.


5. Avira System Speedup




  • Unique variety of performance boost features
  • Adds an information widget
  • Some tools aren’t as detailed as other PC tuneup apps
  • No unlimited licenses


Your computer is like a muscle in some ways. If you don't use it, applications and drivers will begin to go out of date, and become less efficient than when they were newly installed! This may cause huge performance drops, and may even lead to some errors.


Yes, Windows needs regular upkeep, too. Thankfully, there are ways around this problem other than just buying another machine: using Avira System Speedup is one of them. The app includes useful features like defragmenting hard drives to help with low speed issues.


You can also remove unneeded files that take up valuable storage space you could otherwise use for programs or data.


6. Glary Utilities




  • Provides considerable system performance boost
  • User-friendly interface
  • Protects your privacy
  • Built-in tools for driver updates, secure file deletion, etc.
  • Some feature descriptions need to be updated
  • Restrictions for licensing


You might feel like your computer is slowly being eaten away by obsolete registry entries, temporary files, misconfigured services and other computing junk. As a result, the once quick machine may take longer to boot or crash more frequently as it becomes slower over time.


Glary Utilities is a tune-up utility that employs about 20 different tools to eliminate these issues. The app is quite simple and easy to use, but it's limited by licenses as well as the lack of information on what each feature does for your system in general terms.


7. Avast Cleanup




  • Proven to speed up and clean computers with ease
  • Saves power on laptops
  • Automatically updates your applications
  • Easy to use
  • Too many notifications by default
  • Isn’t backwards-compatible with older versions of Windows
  • Some features are only available in the full version


If you're looking to go all out, then Avast Cleanup is where it's at. This program has an easy interface that makes certain tasks easier than in any other app, let alone doing it on your own!


Whether for optimizing your particular operating system, or removing no longer necessary apps and files from your computer — these features will benefit any user looking to reclaim their time on tedious maintenance work. Deleting files and tuning your settings manually is a thing of the past. Avast Cleanup will keep your PC running smoother forever more.
