The 10 best tuning software 2023: test and comparison

You have just arrived at the office and the next session is about to begin. But first you want to start up your PC quickly and send an urgent e-mail. But starting the computer takes, and takes, and takes. You look at the clock and nothing works; the computer "hangs" again. The doorbell rings and the customer is there - the e-mail has to wait. A scenario that many have already experienced. It doesn't have to be, because with one Optimization and tuning software you can fix the problem of a slow PC.

But what are the reasons for a lame computer, what exactly is tuning software, what advantages does such a program offer and what are the ten best optimization software 2020? We give answers to these questions in the following paragraphs, because we have in one PC optimizer test found out which tuning programs can be counted as the best tuning software.


    What is PC tuning software?

    Over time, if you have several programs open at the same time, the system does not start as quickly and the processes become slower. This is where PC tuning comes into play; it helps to increase the speed of your computer.

    • PC optimization programs can improve system settings and make numerous errors as well Eliminate temporary or other superfluous files. A PC tuning program scours through all the storage locations and checks if there is anything to clean up. So you quickly have more storage space.
    • Also broken links Tuning software can repair or completely delete it so that files can be better allocated and the registry can be optimized.
    • Not all services that the computer accesses when it starts are by far necessary. A PC tuning program can disable such services.
    • Ideally, a PC tuning software finds vulnerability on your computer and fix it immediately. Your PC will then run as fast as it did when you bought it.
    • You can also do that with one of the tuning programs or their built-in functions Periodically maintain the operating system and in this way avoid making your computer slow.

    Why was my computer getting so slow? you may be wondering. This can have several causes.

    Tuning software possibilities

    What are the reasons for a slow PC?

    Utilization of the central processing unit (CPU), full memory (RAM) or hardly any free space on the hard disk can cause the PC to become slow. How much memory You can look it up in Windows Explorer, and you can use the Task Manager to find out how busy the CPU and RAM are.

    The reasons for a slow computer are many:

    • Startup Programs
    • Services running in the background
    • Overloaded programs
    • Garbage data on the hard drive
    • Unnecessary registry entries
    • Outdated drivers
    • Overloaded context menus,
    • Malware
    • Disk fragmentation
    One click optimizations can help get your PC back on its feet. But they also harbor the risk of intervening in the system so thoroughly that errors occur and ultimately make the “tuning” counterproductive.

    You should therefore contact a optimization software familiarize yourself and know which function does what.

    Other reasons for a slow PC could be:

    Accumulation of useless dataNot essential servicesfragmentation

    Accumulation of useless data

    In cache cached or installed programs slow down the computer performance and thus especially delay graphics programs because these are computationally intensive applications.

    Many programs save temporary data on your PC during use and then do not delete them when they are no longer necessary. So accidentally collect amounts of data on your hard drive and make it difficult for applications to find the right files. This also applies to antivirus Software or PC tuning software; these programs also have more trouble analyzing the stored data. If you uninstall applications, certain files are still incompletely removed.

    The result: Garbage remains and needs storage space that could be used for other purposes. A PC tuning software can remedy this and remove unnecessary data.

    If programs are executed in the background, this not only means a limitation of the computer performance, but also leads to one in the case of laptops or other mobile devices shorter battery life.

    Not essential services

    Autostart function With a tuning software, you can determine which programs the computer should start automatically when it starts. Antivirus or other are of course Internet securityPrograms, such as VPN services, essential.

    For services that are not absolutely necessary, you can decide for yourself what the computer should start. Although clicking on the program icon may result in slower opening, you can shorten the overall system start-up. Many PC optimization software therefore offer the option in the menu to select or deselect certain services.


    With fragmentation, the computer no longer stores files as huge chunks that belong together, but as split files. Regular writing and deleting means that you will expose more and more small file sectors.

    This happens because, when saving a file, the write head first uses a «gap» and can store the rest in the next available section. In doing so, he saves the files unsorted and fragmented. If you now want to open a file, the read and write head must first "jump around" between the areas so that it can display everything. After a period of time this leads to everywhere slower reading and writing processes.

    PC tuning programs therefore offer a Defragmentation functionthat creates order on the hard drive and sorts scattered files, moves them to new storage areas and saves files as whole, contiguous blocks. It goes without saying that the operating system will be faster this way.

    Unfortunately, it must be noted here that this only applies to conventional magnetic disk hard drives. Defragmentation is harmful to sophisticated SSD hard drives (Solid State Drives), because such flash memories do not have a read or write head, but are generally able to access all memory areas at the same speed.

    Whenever a cell is written to, the “contingent” of write operations shrinks because the memory areas only offer a limited number of possible write cycles.

    What are the other advantages of PC tuning software?

    It is perfectly normal for that to get through intensive use of your computer over time large amounts of data and unnecessary information accumulate. For example, backups are sometimes no longer appropriate. Incorrect registry entries accumulate due to errors in structural components, especially with Windows. They can also result from improper removal of software.

    • This makes the operating system slower and the PC performance leaves much to be desired. With a PC tuning software - as the name suggests - you can counteract.
    • One of the other advantages of PC optimization software is the Update of drivers and software are counted. A more stable system results in fewer crashes and faster computer startup.
    • Thanks to the elimination of unnecessary garbage, a faster computing power, which is especially noticeable when you use several applications at the same time.
    • A PC tuning program deactivates programs that were previously running in the background and increases battery life.
    • The Repair function Tuning software rounds off damaged systems.

    Tuning software optimization of the PC

    What should be considered when buying a PC tuning software?

    While servicing your system can do wonders in terms of performance, some servicing functions can be detrimental if used improperly. You should therefore always be aware of which function does what on your computer.

    • You should only run an optimization step if you really know whether it is will be useful to the operating system. If you are not sure and do not want to take any risks, you do not have to leave everything activated; you can also switch off individual settings. Especially if you are a layperson, we recommend that you narrow down the problem area and not make extensive changes.
    • The cleaning up is more for professionals Windows registry - the brain of the Windows computer, which for example stores the maximum screen resolution available for the graphics card.
    • Inappropriate settings can cause programs to work incorrectly, and that is exactly what tuning software is for. A PC optimization program is not omniscient and can mistakenly see potential savings where there is none.
    • Many internal program settings are stored in the Windows registry. A database too big leads to a slowdown of the PC, but as I said, it is better to be careful than to be safe, because in the worst-case scenario there is a risk of a system crash.
    • When buying a PC tuning software, you should also check whether the program even workst compatible with the upgradeable operating system at a hunt.
    • There are also Licenses Differences. Not every solution offers more than one license. For you, this means that you cannot always optimize all the computers in your possession with tuning software.
    • In addition, some programs can also a smartphone or tablet optimize, others do not.
    • Then there is next to paid software also includes free tuning solutions.
    • And what about that Refund warranty out? A trial period is not always possible. Some tuning software providers have developed a compromise solution - a demo version that discovers and also shows potential for optimization, but only allows the problem to be resolved after purchasing the PC Optimizer software.
