System Mechanic 16 Frequently Asked Questions

The answers provided in this FAQ pertain to System Mechanic 16 for Windows 7 through 10. A specialized version of System Mechanic for Windows XP is detailed here.

1. WHAT’S NEW about System Mechanic 16?
     System Mechanic has been completely redesigned to take full advantage of both modern machines and the major advances to the Windows OS starting with Windows 7.

Among the highlights:

  • System Mechanic 16 leverages today’s powerful multi-core processors to scan for slowdown in several areas of your PC at once, and then repairs those issues simultaneously as well. For example, it searches for trapped memory while also locating junk internet files. This means the scan and repair functions are now many times faster than any release to date.
  • iolo engineers have also redesigned, consolidated and simplified the major flagship tools to get the best performance out of your specific operating system. The result is the most powerful and stable PC accelerator available today, faster and easier to use than ever before.
  • The new iolo Smart Updater delivers nearly instantaneous updates to ensure you receive the most recent version automatically and seamlessly. Individual components and features can now be updated without a re-release of the entire System Mechanic product. This allows for more frequent product enhancements based upon your feedback.
  • System restart is now rarely needed during the system update process.
  • The next generation of Tune-up Definitions is now capable of continuous, real-time updates that find many effective new optimizations for today’s modern apps. The result is the elimination of many more types of slowdown, especially in Windows 10.
  • Startup Optimizer features these next-gen Tune-up Definitions that can help to significantly speed up boot time by discovering whole new categories of unneeded startup items while providing more user control over Dangerous and Unnecessary ones.
  • System Mechanic 16 features the smallest footprint of any version yet, using on average less than 0.5% of processor resources when open and idling.*

2. What are the main changes to the USER INTERFACE in Version 16?

  • The streamlined Dashboard no longer features separate Overview and Issues tabs. Simply scan for issues with one click, and then Repair All with another click.
  • Many individual tools and wizards have been consolidated to eliminate and simplify tools, tabs and dialog boxes with overlapping functionality, so repairing and optimizing is fun and efficient.
  • Sleek, easy-to-read vector graphics are optimized to scale in response to today’s larger 4k displays.

3. Where are the ALL-IN-ONE TOOLS?

The All-in-one Tool functions have been fully incorporated into ActiveCare and the Clean, Speed Up, Protect and Recover tabs for ease of use.

4. What happened to PC TOTALCARE?

PC TotalCare now launches when you click on Repair All after scanning for issues.  


Microsoft defragments and compacts the system registry in Windows 7 and above, necessitating only that System Mechanic clean the registry. Therefore, Registry Tuner is the only registry repair tool needed—to periodically clean out the system registry.


Junk File Finder is now listed as "Windows Cleanup," and also functions within the All-in-One PC Cleanup tool.

Privacy Cleaner is now listed as "Internet Cleanup," and also functions within the All-in-One PC Cleanup tool.

   Registry Tuner is now listed as "Registry Cleanup," and also functions within the All-in-One PC Cleanup tool.

9. What happened to SHORTCUT REPAIR?
Shortcut Repair's functionality has been folded into the PC Cleanup tool, with no separate tool interface required.
10. What happened to STARTUP MANAGER?

Startup Manager’s functions have been absorbed into Startup Optimizer.

11. How do I launch the file INCINERATOR?

After the initial install of System Mechanic 16, go to Toolbox >> Protect and click on Incinerator. This will automatically create a convenient desktop icon. Simply drag files into this bin to incinerate them. Clicking on Incinerator from theToolbox >> Protect menu once again will uninstall the desktop icon. 

12. Which tools have been PHASED OUT?

Some tools with either overlapping functionality or that were determined to be obsolete in the more modern versions of Windows have been eliminated from the new streamlined System Mechanic 16:

  • SSD Accelerator
  • Registry Compactor
  • Process Manager
  • Drive Medic
  • System Change Tracker
  • Most of the tools in the Manage category, specifically:
    • Advanced System Information
    • DriveSense
    • NetSpeed Analyzer
    • The PC Health Status Gadget (Windows 7 only)

13. Which features are planned for further refinement and reintroduction?

  • CRUDD Remover
  • Duplicate File Inspector
  • Registry Backup
  • Designated Drivers

14. Are there changes to LIVEBOOST?
      LiveBoost’s four signature tools—OptiCore, PowerSense, AcceleWrite and RAMJet—have been further fine-tuned to maximize processor, hard disk and memory performance in later versions of Windows.

15. Are there changes to ACTIVECARE?

ActiveCare’s automatic repair and maintenance functions operate more efficiently within the new architecture. If all of the functions within ActiveCare are Disabled, a Recommendation to Enable ActiveCare will appear after System Mechanic performs a system analysis. Note that if you have any settings at all within ActiveCare Enabled, you will not receive a Recommendation.

16. Does System Mechanic 16 SUPPORT WINDOWS XP AND VISTA?

While System Mechanic 16 focuses on fully leveraging Windows 7 through 10, a special version of System Mechanic for Windows XP and Vista, System Mechanic Classic, retains all the classic tools and menus that benefit those older operating systems. If you are running Windows XP or Vista and you attempt to install System Mechanic 16 on your machine, you will receive an install error message.
