Let’s begin our System Mechanic review with a short introduction to the product.

System Mechanic is a product by Iolo that works like a PC optimizer. This PC tune-up is a powerhouse that features a slick suite of tools that dramatically improves your PC's performance. It deletes junk files, cleans the hard drive, and tweaks RAM usage in real-time. It is a quick and simple way to clear all unwanted files from your computer. It’s a utility like CleanMyMac and MacKeeper, but exclusively for Windows PCs. 

Apart from being a great computer tune-up system, it also provides excellent security and privacy. With System Mechanic, you can enjoy safe browsing while ensuring optimal PC performance.

System Mechanic Product Features and Tools

In this part of our Iolo System Mechanic Pro review, we will talk about its features and tools. The System Mechanic family has three products:

  1. System Mechanic
  2. System Mechanic Professional
  3. System Mechanic Ultimate Defense

In general, System Mechanic has a series of next-generation automated maintenance tools that help keep computers clean, and stable. They dig deeper into the system to smoothly and swiftly adjust the processor, hard drive, and memory settings for optimum performance and speed.

System Mechanic comes into action whenever your computer is idle and consistently removes junk files, registry fragments, and other clutter that may affect Windows's speed and performance.

In our review of System Mechanic, we’ll explore the features in detail.


PC Cleanup 

This feature helps clean out Windows files and junk from the internet. It uninstalls programs that are not needed and repairs registry errors for privacy protection. It basically helps speed up PC and frees up disk space.

Advanced Uninstaller 

With this, you can completely uninstall application files to avoid slow PC performance and improve drive capacity.

Keep Hard Drive Clean and Error Free 

It automatically deletes junk files that are left behind by system freezes, sudden restarts, and untidy programs. It can help you promptly fix hundreds of errors that involve system components, installed hardware, software, and hard drive.

Speeding Up

Net Booster

Iolo reviews highlight the Net Booster as one of the greatest features for boosting PCs. It allows you to custom-tune over a dozen hidden DNS and TCP/IP settings for a speedy broadband experience.

Disk Defragmenter

It defragments data files, which helps improve disk read and write speed, thereby offering you better and faster file access.

Program Accelerator 

Most Iolo System Mechanic reviews praise the Program Accelerator. This is the feature that realigns programs on the hard drive. By realigning the files, you can speed up the system and its programs.

Maximize Free Memory

This feature helps free RAM by idle apps that improve system stability and enhance speed. Moreover, the deep cleaning mode flushes the memory capacity and only reloads the applications that are needed.

Now let’s focus on privacy and data protection because the last thing you want is to become a victim of cybercrime or identity theft.

Privacy Shield 

The Privacy Shield is best when it comes to recovering privacy in Windows 10. The features work by turning off Microsoft’s aggressive new personal data collection services that are difficult to disable fully otherwise. This will ensure that the information about your web browsing habits, sites, and program usage is not being collected. Put simply, the Privacy Shield allows you to opt-out of sharing personal data.

If you are concerned about your privacy we suggest using a VPN service

You can also disable location services. These days, laptops, and tablets are built-in with location devices like proximity sensors, WIFI technologies, and GPS modules. They help vendors provide highly precise information about the users' past and current locations, which can be sold to third parties for targeted advertising and profiling. However, those who don't want to share this information can genuinely benefit from the Privacy Shield feature of System Mechanic.

Another significant aspect of the Privacy Shield is that it also disables the smart screen service. This is a service that collects data from users’ web browsing history and then sends it to Microsoft. Simply stated, the privacy shield is indeed the best way for Iolo developers to keep users of System Mechanic protected from compromised computing experience.

Security Optimizer 

Hackers, malware, and other internet dangers pose a high risk and wreak havoc by destroying data, causing computer damage, and enabling identity theft. Apart from the usual options, the Security optimizer feature is a great way to bolster system protection and take it to the next level. It finds and repairs security flaws and errors in your Windows system before they become a risk.

If you are worried about your system’s security, make sure you have an antivirus solution installed. 

Registry Backup

Since we are doing a System Mechanic Iolo review, how can we miss the registry backup tool? As the name suggests, the Registry Backup allows users to protect their registry by carrying out regular backups. It is essential to do so because the system registry is critical to your PC's ability to run correctly. 

System Guard 

The System Guard helps stop malicious programs from loading on your system and blocking changes to internet pages. With this feature, you can configure automatic system defense. Hidden files can change your browser's search page or homepage pointing towards their website. But the System Guard protects you from it by blocking unauthorized changes to your PC without your permission. 

Apart from System Guard, another tool we want to shed light on in our System Mechanic review is the Incinerator. Here’s why:

The Incinerator

This works like a recycle bin with a military-grade file shredding technique. It combines the separate desktop strength into the standard Recycle bin of Windows.  Therefore, it gives you the ability to delete files using Iolo's incinerator technology. It securely and permanently deletes files and folders in Windows.

System Restore

This feature gives you the power and flexibility to undo recent changes. So, if you want some files back, the restore feature can help you retrieve them quickly without any hassle.


ActiveCare is a tool that ensures smooth and effective PC optimization. This involves a series of processes that run when you leave your system idle. It stabilizes and declutters the PC to ensure the best overall system health. It silently checks for and repairs a computer by diagnosing, tuning, and fixing as required. The ActiveCare activity stops the moment you're back to work. This ensures a healthier and faster system with minimal disturbance while no maintenance activity interferes with your use of the PC.


We’re pretty sure that one of the reasons why you turned to our System Mechanic Review was because you wanted to speed up your PC. Enter PowerSense. Speeding up your computer has never been this simple. With this feature, you can ensure a real-time performance boost. It helps optimize the speed and availability of your RAM, CPU, and other storage drives.

PowerSense allows you to automatically switch off your processor's settings to accommodate your computing's central functions. It quickly adjusts the resources of the PC when it sees the user working on high-demand applications or where good system stamina is needed. Also, it can scale back at less system taxing time, which helps save power.

PowerSense includes built-in modes. These are finely tuned improvements. Reviews of System Mechanic praise it and here’s why:


This helps speed up processor cores by turning non-essential processes. This action delivers you maximum system speed whenever Steam is launched.

Video and Music Production

When more than twelve video or music programs are launched like Premiere after effects, the tool shutters background processes for optimum performance.

Graphics and CAD Design

This power mode comes into action whenever you launch graphic design or animation programs such as Adobe Illustrator, Photoshop, Prelude, Paint Shop, Designer Pro, Maya 3D, EdgeCam, Cinema 4D, ZBrush, etc.


It engages when one of the following programming apps is launched: Microsoft Visual Studio, Delphi Desktop, Cross Compiler, Command Line Compiler, Netbeans Java, MadCap Flare, and Lazarus.

Maximum Battery

This mode helps scale back processor cores to 25% of maximum speed. Moreover, it reduces screen brightness to 60% and turns the hard drive off after five idle minutes.

Now, here’s what else we found pretty important to mention in our System Mechanic review:


Many System Mechanic reviews mention OptiCore but fail to explain it in detail. We’ve got you. 

This feature is known to end two decades of PC industry frustration related to the system speed compromise due to low priority programs. Opticore is a cutting-edge technology that prevents low-priority programs from system corruption, PC lags, and freezes. It increases PC responsiveness and is considered a significant milestone in the PC optimization domain. Opticore is an excellent feature for speeding up Windows 10


Another feature that puts System Mechanic among the best PC optimization software today. It takes back the trapped and disjoined memory that is used by idle programs. It then adds it to the overall cache of available fast memory.

This tool perceives the exact times when the system is taxed by heavy workloads and reallocated RAM. Furthermore, when the available RAM falls below 35% of the total memory, RAMJet goes through the system, searching for trapped memory to clean up space. You’ll notice an improved system performance almost immediately. 

With RAMjet, you also get back precious RAM in real-time, thereby sparing you from running separate tools or worse - reboot. 


This tool enables file writing to disk in contiguous batches, thereby improving the system's overall performance and reducing the need for secondary file defragmentation.

Interface and Ease of Use 

System Mechanic has a user-friendly interface. The program is super easy to browse through, as we discovered when testing it for this System Mechanic review. All the options are in detail so that you can have maximum control over them and use them to your full advantage.

All tools and features are listed with subcategories and can be initiated in just one click.

Customer Support

You can reach the customer support team online and by phone. You can call them at 8:00 AM to 5:00 PM (Pacific Standard Time), Monday through Friday, excluding holidays and scheduled maintenance periods. Also, phone support is only available in English.

Paying customers get 24/7 support.

Last night I purchased System Mechanic Basic for $14.99 in hope it would live up to its billing and improve my wifi reception. (I live in the Philippines) I have a new PC with good specs. and at times is slow and the router could take as long as 2 hours to boot up. The big problem for me was I kept losing my connecting when I was playing an online game (WGT) As soon as it was installed I no longer had that problem and the PC is running smooth. I'm still amazed.

I've been using Sys Mech Ulti Def for years and this is the worst version ever... I don't like it at all and want to revert to the previous version.

I’ve used this for at least 20 years - it’s a good product. Basic works for me. You can renew at $19.95 or so. I just renewed so have 335 days left on license. Not happy to see $19.95 on my credit card so i called them. This is the monthly charge for 24/7 live tech support which I did not sign up for, have not needed to use once since I’ve used the product & do not want. You DO NOT NEED this, it has no impact on the product & is NOT part of a monthly ‘service’ fee. Call them & cancel, make sure the entire amount gets cancelled because (in my case) I found the charge on my card today & was told that would have to be refunded. Put on hold twice for each one of these transactions. But since they had me on the line I was offered a bargain discount price good for today only of $179 a year vs $240. This deal is provided by USTech support. Maybe this is one of those tiny tiny type things buried somewhere. Read read read the small type if you can find this. It’s kind of a sleepy thing to do. You don’t need it & it’s not part of the product.
