Overview of key features Back to the top

Boosts Speed

Automatically increases the speed and availability of CPU, RAM and hard drive resources when you launch high-demand apps for the smoothest gaming, editing and streaming.


Finds and fixes over 30,000 different issues using intelligent live updates from iolo Labs™ to keep your PC stable and issue-free.

Removes Bloatware

Identifies unwanted startup programs that slow you down by launching and running without your knowledge.

Protects Privacy and Security

Safely wipes sensitive browsing history and patches Windows security vulnerabilities that can harm your computer.

Unleashes Internet Speed

Automatically optimizes hidden Windows Internet settings for faster downloads, snappier page loads, less buffering, improved video quality and smoother gaming.

Cleans Out Clutter

Removes over 50 types of hidden junk files to free up valuable disk space and make more room for your documents, movies, music and photos.

Disable Cortana virtual assistant

This commonly used feature sends to Microsoft enormous amounts of data related to precisely how you use your computer.

Disable camera and microphone access

When access to these tools is enabled by default, you are allowing all of the apps on your computer access to them. Many types of malicious attacks access camera and microphone through vulnerable apps, to spy on you or steal your personal information.

Disable activity history collection

This feature, particularly when the Send my activity history to Microsoft box is also checked, risks exposing unknown quantities of information on how you use the apps and services on your computer.

Phishing Detector

This new technology within Privacy Guardian looks to see whether incoming email is from a proxy DNS server, a common indicator of potential phishing attacks as the sender attempts to mask their identifying information, such as true IP address.

What’s new in System Mechanic 21? Back to the top

System Mechanic has a new look:

  • New! Streamlined installation flow

A modern redesign streamlines and simplifies the user experience. Enhancements include:

  •  New! Streamlined installation flow

We significantly reduced the steps to install System Mechanic, given you quicker access to the powerful suite of System Mechanic products.

  •  New! Clean and simplified dashboard 

We gave System Mechanic a fresh new look to showcase the best System Mechanic has to offer, while also making it easier for you to navigate through the product. 

  •  New! In-product tutorials

Helpful dialog bubbles point you toward and guide the best use of the powerful features within System Mechanic.

New! Network Scanner

This new feature scans for devices on your network using bandwidth that could be causing congestion.

  • If you are experiencing significant slowdown, it may indicate that router ports are open and vulnerable to inviting spoofed DNS and other malicious queries.
  • Hackers use automated scanners to check for open router ports and label them susceptible to attack.
  •  Open ports will eventually attract attacks that try and guess your router login credentials, but threats go far beyond this.
  • Security cameras, thermostats, gaming consoles, smart TVs, phones, speakers and many other connected devices can be exposed to hacks.
  •  You could even be recruited as part of a Distributed Denial-of-Service (DDoS) attack, which saps bandwidth you've paid for.
  •  Network Scanner finds and lists active and potentially vulnerable devices, helping you avoid unnecessary slowdown and protect your home from malicious threats. 


New! Process Scanner

Now you can also scan your computer for processes that are currently draining the most system resources, likely leading to preventable slowdown.

  •  The perfect complement to the bloatware-finding feature Startup Optimizer
  •  Lists unnecessary processes currently running in real time
  •  The most system-taxing items are listed first
  •   Recommends terminating or uninstalling apps you may no longer need
