System Mechanic 17.5

Among thebiggest causes of PC performance degradation after the latest Windows updates are unnecessary bloatware that runs without the user's knowledge and applications that sneak into the startup process (and are automatically loaded with Windows).

What's new in version 17.5?

The new system Mechanic 17.5 now contains Super Definitions™, a significantly more precise and enormously extended version of the innovative program classification system of iolo. This decisive further development of proprietary technology - formerly known as tune-up Definitions™ - is used to detect and eliminate unwanted startup programs and bloatware running in the background, which are the biggest causes of performance problems on the PC in times of modern Windows®. 

Extended The Super Definitions™-database with more than 40,000 programs and processes is now in its second generation.

  • The enhanced database now recognizes and classifies all scheduled tasks, not just those that are executed at startup.
  • The classification system benefits from an expanded research area at iolo Labs, allowing even more program types to be found, analyzed, and classified.

  • Thanks to these enhancements, System Mechanic is even better able to detect the latest applications, tasks, and services that burden the system by running in the background without your knowledge.


Improvements in Version 17.5

Expanded  Startup Optimizer™ uses the improved super definitions and finds even more types of unwanted startup programs and continuously running tasks and services. allows you to choose whether to enable or disable unwanted programs.

Most important improvements to Startup Optimizer™:

  • More community recommendations have been added so that you can find out which programs most users enable or disable.

  • As computers become more powerful, more of these unwanted applications and processes are smuggled into the startup process.

  • Up-to-date, comprehensive, and accurate identification and classification of these items is important so that you can safely disable the ones you want to, thereby improving computer performance.

  • By restricting the programs that are loaded at startup, you can reduce the load on memory, CPU, video card, and hard disk and make your computer run faster.

Enhanced Product Recommendations are now displayed in exam results and provide easy access to the free version of two new iolo products:
  • Privacy Guardian Free for online tracking and digital fingerprint recognition

  • ByePass Free for secure password management

Other improvements
  • Improved Quicksilver High-Performance Platform™ - Now completely new categories of problems are found in Windows, which can be solved by optimization.
  • Improved ActiveCare® - Offers complete control over how junk files are removed from Windows and the Internet. Now you can individually choose to delete expired browser cookies, cache files, clipboard data, temporary files (five different types), and other data.
  • Enhanced Privacy Shield™ - It disables the broadband consuming Windows Update transmission optimization, preventing it from interfering with your Internet connection.
  • Improved NetBooster™ - You can configure specific broadband settings for streaming, gaming, etc.

System Mechanic 17.5 finds and eliminates both known and potentially unnecessary newly discovered objects and programs that unnecessarily burden the system - from junk data and file fragments to unwanted applications running in the background that use up unnecessary memory. This ensures maximum Windows performance.

Other functions


A defragmentation of the hard disk ensures that parts of a file previously "wildly" stored on the disk are stored next to each other where possible. This reduces the mechanical movements required to read from the hard disk - Windows can access and open files faster. This measure increases disk performance, reduces the risk of data destruction and extends the life of drives.


When installing Windows, the basic configuration is rarely optimized for your personal Internet connection. This often results in the maximum possible values for uploading and downloading on the Internet not being reached. System Mechanic's NetBooster® technology provides the maximum data transfer rate for your Internet connection, resulting in a faster and more reliable connection.


Installing and uninstalling new programs will fragment the registry and inflate it unnecessarily. A regular defragmentation restructures the registry and helps Windows to load the necessary data faster; the compression of the registry leads to the removal of unused free spaces that unnecessarily enlarge the registry. Both processes work together, speeding up access to programs, improving system performance, and freeing up system memory.


Defragments system memory, which can result in a noticeable increase in performance. Defragmenting the system memory can also lead to greater stability of the entire system, as too little memory is often the cause of computer freezes and system crashes.

    Ultra Performance focuses on all cores of the processor during a performance-intensive session, disabling all programs that run in the background and are redundant: So the PC tunes up its capacities when necessary.
  • Endurance Mode - Reduces battery power consumption during long periods of notebook use, especially for activities that do not require special performance, such as word processing programs or surfing the Internet.  
    In Endurance mode, the processor of the PC with the lowest performance works to reduce energy consumption
