Best 22 PC optimization software - November 2019

Computers, especially those running on Windows, can easily become corrupt and slow over time. Resulting in unpredictable behavior, sluggishness, incorrect files and software, etc., it gets simply annoying at some point. PC optimization software is there to help carry out usual tasks again and to clean up.

PC optimization utilities perform deep scans, find and fix problematic areas. Repair functions may include hard drive defragmentation, registry repairs, RAM and disk space freeing, junk file removal, etc. Some are basic, others are more advanced, while all of them have ‘repair all/fix all’ option. We tested every utility in the same repetitive manner on a 8GB RAM PC on Windows 7 Professional.

9 out of 10 PC optimization apps have a free version or a trial period along with paid annual license to use, while one app is totally free. Whichever way, they’ll help you optimize your slow PCs for faster response, quick task handling and better overall performance.

More about PC optimization software

What is PC optimization software?

PC optimizers are a special category of software that help improve the speed of user’s device. Using built-in tools, users can conduct regular maintenance of operating system to prevent slowdowns. In addition, these programs help to remove temporary and unnecessary files to increase free disk space. Also, most of optimization software can aid in system settings or elimination of common errors.

Why use PC optimization software?

Any long-term and intense use of OS accumulates large amounts of unnecessary information, like outdated backups for instance. Windows OS is especially characterized by the accumulation of failed registry entries caused by unfit removal of software, errors in structural components. These factors reduce the speed of the system, which leads to a drop in PC performance. So optimizer tools are one kind of remedy against that.

Is registry optimization relevant?

Windows operating system uses registry as the key logbook of global and small system settings. To understand how the registry works, imagine that you need to pay one paper bill every day, but before paying, you must check all previous bills and always carry them with you. Over time, this procedure will require more and more time - so will accessing a registry entry, with many unnecessary keys.

How do PC optimizers work? Do they clean or repair?

Many programs keep logs of different detail degree for monitoring and critical errors detection. In process, they produce temporary files that are not always deleted, and further accumulate in the system, occupying space. OS also remembers previously used programs and files to provide quick access just in case. All of it leads to accumulation of vast number of files that are not necessary, but stored on disk. PC optimizers search unnecessary files in known locations, then delete them.

Active monitoring vs Scheduling

Active monitoring tools, built in optimizers, perform real-time monitoring of the system state. Users can set up conditions and requirements for monitoring and consecutive cleanup. Scheduling option allows to run a checkup and optimization upon specified time periods.

What is defragmentation?

This is an operation of structuring data on a disk. HDD store information in special cells - clusters of small size. Files are recorded in these cells, sometimes resulting in a situation where one file can be dispersed in cells. And if those cells are located at a great distance one from another, it could cause system crash when accessing a file. Defragmentation organizes data in clusters, so that files will no longer be scattered afar.

File optimization

This is a set of tools for one of aspects of PC optimization:

  • File explorer - utilities with it provide reports about file sizes and disk space.
  • Duplicate finder - detects duplicate files located in different directories. But use with caution, as to not delete critical ones.
  • File undelete/restore - to recover accidentally deleted files.
  • File shredder - to delete files permanently, without the possibility of restoration.

User tips

To perform PC optimization properly there are few suggestions. Use autorun optimizer - as often slowdowns are caused by big number of processes that automatically launch at system startup, disabling unnecessary applications will definitely free up resources. Be careful with registry cleaner - always back up registry entries before cleaning it, because optimizers cannot always distinguish the correct entry from the outdated one.

Do not clean everything automatically, at least when you run this feature for the first time. Always check carefully, which files you allow to remove, or choose to clean by script. There is always a risk of deleting temp files that are needed by OS. Backup changes - most PC optimizers have built-in tools for archiving changes caused by optimization. Before the first cleaning, we recommend setting up backups (or system restore points) to prevent system crashes.

Top examples of PC optimizer tools

iolo System Mechanic is a time-tested utility, offering a set of utilities for automation, along with new technologies for PC monitoring. IObit Advanced SystemCare - a convenient program for average users, where tools are divided into categories and contain descriptions. Razer Cortex: Game Booster is a program that stands out from competition due to focus on gaming experience and and respective optimization.

According to Google Trends (despite statistics that vary from period to period), users still prefer integrated solutions for system optimization. The second place goes to cleaning of temporary files, an option which, along with defragmentation, are the basic functions of any integrated solution for PC optimization.

Testing the best tune-up tools

We ran each utility on the same PC, in the same environment, repetitively. We didn’t count performance boost in percentage, because it would be inaccurate due to testing 10 apps in a row. In terms of performance, 2 utilities – Advanced SystemCare and Wise Care 365 – found the biggest number of issues, though its relative in a way too. Razer Cortex gave the most considerable RAM boost. But judge for yourself.

How to optimize PC for gaming [short manual]

Step 0: Safety. Always create a backup, before making any critical changes to the system. In Windows, you can do it by using the recovery point creation tool.

Step 1: Drivers. First, install the latest hardware drivers, as game developers typically use the most advanced technologies in graphics. So with outdated drivers you will not be able to enjoy all the visual effects and will have losses in FPS. You can check your drivers relevance via one of driver updater category.

Step 2: Autorun. The autorun list is one of the most misunderstood reasons for slowing down your PC. Each application launched from this list at system startup consumes PC resources, and is not always necessary at the moment. Turning off unnecessary applications will allow you to free up resources for gaming.

Step 3: Cleaning. Clean up the system drive from unnecessary files with help of one of optimizer app to free up space. We also recommend optimizing the registry to speed up the access to it.

Step 4: Run applications. Terminate all applications, except antivirus solutions. We do not recommend disabling antivirus software during the game, especially if it is an online game. Instead, use the Game / No notifications modes.

Step 5: Paging (only for experts). Increasing the paging file will allow to create the necessary memory reserve in case the basic amount of RAM is not enough. This could help to avoid slowdowns during resource-intensive moments in a game.

Step 6: Reboot. After having completed previous steps, restart the system and make sure it works stably. If any errors occur, restore the system to the previous state, using recovery tools. Have a nice game!

FAQ

What is the best PC optimization software?

It depends on user skills and how intensely the OS is used. You can start with free or basic solutions and see where it gets you. 

How to optimize Windows 10?

All modern PC optimization programs, listed in directory and topic above, support Windows 10 (System Mechanic, Advanced Care, Wise Care 365, and others).

What are free PC optimizers?

Freemium - iolo System Mechanic, ioBit Advanced Care, Ashampoo WinOptimizer. Totally free are Razer Cortex, Advanced System Optimizer, WinUtilities.

How to optimize PC fan speed?

We do not recommend changing hardware settings, because this may be grounds for warranty cancellation. The high speed of cooling fans indicates high temperature of heating components, the processor in particular. To cool it, try optimizing PC and reducing overloads. If the issue persists, contact service center and request system unit dust cleaning.

PC optimizer suggests deleting files from system folder/disk. Is it safe?

It is safe, but always use tools for archiving beforehand. We also recommend to make a full backup of the system using Backup Software or Disk Imaging software, at least once a month.

I deleted junk files, but PC optimizer found them again

This means that files are still in use by OS and therefore not available for deletion. Try to remove them after restarting the PC.

What is disk checking?

Hard drives are usually divided into clusters, and sometimes when writing/reading these clusters, failures happen that could lead to a system crash. Disk checkers fix clusters, and if they cannot be fixed, remove them from the list of available clusters. We recommend to perform this operation regularly (once a week), before defragmentation, to prevent data loss.
