System Mechanic Professional is an advanced version of System Mechanic, a PC maintenance and tune-up program for the Windows operating system.

It adds additional tools such as antivirus and antispyware to System Mechanic which makes it an interesting option for customers who require these tools as well.

Many computer users have the impression that their systems become just a little bit slower with every day of use. Software installations, updates and even user actions on the PC can turn a powerful PC into a painfully slow system that is no pleasure to work with.

System tools like System Mechanic Professional have been designed to find issues that may affect the performance of the computer and fix them.

System Mechanic Professional Review

The installation of the program is uneventful for the most part. You can customize some features, like whether you want the antivirus component to be installed with System Mechanic Professional, or if you want a desktop icon to be placed on the desktop of the system for fast access.

Please note that you may need to restart the computer after installation before you can run the software program.

First Start and use

When you first start System Mechanic Pro you are asked to run an analysis of the system. The program checks common problems and issues and displays its finding on the screen. The scan itself takes less than 30 seconds to complete and rates the PC's health, security and overall status.

While you could hit "repair all" on the screen to have the program fix all the issues that it found automatically for you, it is recommended not to do that as it may make changes to the system that you don't want to be made.

The program lists the issues that it found as well as how many recommendations it has for you. You find the different sections that the program analyzed, for instance system clutter or Registry cleaner, and the status of these sections.

Problems can be both security or health related, for instance that Windows Firewall is not running, that the computer has known security vulnerabilities or that the Internet connection is not optimized for maximum speed. Chance is, all are highlighted on first scan of the PC.

You can address each issue individually using the action buttons next to each issue found. You find several options there usually, one to let System Mechanic Professional deal with the issue automatically, and another to start a tool instead that displays the issues found to you so that you can select what you want removed and keep.

clean pc clutter

If you select to review the system clutter findings for instance, you are taken to a new page in the software that displays recommended and optional actions to you.

For this particular tool, it would be to remove the cache of popular browsers as well as Windows and unused downloaded Internet program files.

A click on the plus icon next to an entry displays how much space the temporary files occupy on the system, and how much files there are in total.

Unfortunately, it is not possible to go any deeper than that by having the program list all the files it discovered.

Once you start fixing issues your overall system status may improve from its previous rating. System Mechanic Professional suggests to run a deep scan once the initial issues have been resolved or ignored by the user. A deep scan analysis takes longer to complete but finds additional problems that the quick scan may not have found.

Deep Scan among other things checks if the Registry is fragmented or if Solid State Drives have been optimized.

System Mechanic Professional Toolbox

system mechanic professional toolbox

The toolbox lists all-in-one tools and individual tools. All-in-one tools are system tools that can accelerate, repair, cleanup or secure the PC with one click.

The following all-in-one-tools are available:

  • PC TotalCare - Runs all the tools listed below.
  • PC Accelerator - Checks for performance enhancing actions. This may include defragmenting the Registry, optimizing the operating system drive or recovering and defragmenting system memory.
  • PC Repair - Repairs crashes, system failures and other PC related errors.
  • PC Cleanup - Can be used to delete temporary files on the system to free up disk space.
  • PC Security - Repair and resolve security issues, and perform actions that improve system security.
  • Total Registry Revitalizer - This program backs up the Windows Registry, runs repair operations on it that remove invalid and obsolete data from it, and defragments and compacts the Registry in the end.

Individual Tools

system mechanic professional tools

The individual tools group lists specialized tools, from optimizing the Windows startup to repairing shortcuts, recovering deleted files or monitoring the hard drive status.

Some of the tools are used by System Mechanic's scans, while others are specialized tools that can only be started directly from the toolbox.


  • PC Cleanup - Scan for and remove temporary files on the system to free up disk space.
  • Junk File Finder - Find and delete obsolete and unneeded files.
  • Privacy Cleaner - Erases private data like cookies, chat transcripts or the search history.
  • Registry Tuner - Repair Registry problems like obsolete data references
  • CRUDD Remover - Detects and offers to remove redundant applications (e.g. CCleaner when System Mechanic is installed).
  • Shortcut Repair - Repair broken shortcuts.
  • Advanced Uninstaller - Remove installed programs..

Speed Up

  • NetBooster - Optimize Internet settings to improve the Internet connections stability and performance
  • Program Accelerator - Speed up programs by re-aligning the data on the hard drive
  • Memory Mechanic - Defragments the system memory.
  • Startup Optimizer - Suggests start up items that may slow down system start.
  • Startup Manager - Manage and configure Windows startup items.
  • Registry Compactor - Defragment and compact the Registry to speed up the start of the PC
  • Process Manager - A Task Manager that you can use to manage running programs.


  • System Shield - Scan for malware, manage the quarantine, settings and history.
  • Security Optimizer - Scan for and fix Windows security vulnerabilities.
  • Privacy Shield - Disable privacy-invasive features of the Windows operating system such as Wi-Fi Sharing.
  • System Change Tracker - Tracks changes that have been made to the system.
  • DriveScrubber - Wipe data securely stored on hard drives or removable drives connected to the PC.
  • Incinerator - Like DriveScrubber, but for individual files.
  • Registry Backup - Create a backup of the Windows Registry
  • System Guard - A program that blocks malicious programs and processes from loading and interacting with the system


  • Search and Recover - Recover individual files, pictures, movies, songs, emails, or entire drives or disks.
  • System Troubleshooter - Disaster recovery when a drive becomes unstable
  • Drive Medic - Find and fix hard drive problems. Option to create a Drive Medic Emergency CD to boot from it when the operating system cannot be started


  • Designated Drivers - Scan for outdated drivers and suggest updates
  • Advanced System Information - Display system information like the installed hardware or software
  • Super Control Panel - Customize advanced Windows settings.
  • DriveSense - Monitor the hard drive status
  • NetSpeed Analyzer - Benchmark the Internet connection

Several tasks can be automated to run regularly. This includes repairing Registry and hard drive errors, removing temporary files or backing up the Registry regularly.


active care

ActiveCare is System Mechanic Professional's automatic mode. It is disabled by default but can be enabled to let the program optimize the following things:

  1. Optimize the PC's startup configuration.
  2. Optimize the PC's Internet configuration.
  3. Defragment and compact the windows Registry.
  4. Repair WMI conflicts.
  5. Repair Registry problems.
  6. Repair broken shortcuts.
  7. Repair broken Internet connections.
  8. Repair security vulnerabilities.
  9. Back up the Windows Registry bi-weekly.
  10. Scan for viruses and spyware on a regular schedule.
  11. Clean up system clutter.
  12. Download and install updated tune-up definitions.

Bascially, it allows you to automate most of the program's features that you can run manually as well at any time.



LiveBoost has been designed to optimize the performance of the PC by handing over control of some features to System Mechanic Professional.

You can enable that for the cpu cores, computer memory, hard drives, and power management.

You find configuration options on an extra page that highlight what each of the tools does when enabled.

OptiCore for instance tries to balance cpu demand for maximum resources, while RamJet to maximize the available RAM. A click on details reveals additional information on how that is done.

Internet Security

system shield

If you have installed the anti-malware component during installation, you get the option to configure and use the program's system shield functionality.

Use it to run manual scans for malware, update the virus definition database, or enable or disable real-time or email protection. There you also find options to manage Windows Firewall.

System Mechanic Professional Reports

system mechanic reports

Reports is an interesting page as it lists a summary of System Mechanic Professional's findings on a single page plus extra information that you may find useful.

It lists the free space of individual disks connected to the PC as well as the total free space available, and the same for system memory.

Then it lists startup programs and running programs, and categorizes them into system, necessary, optional, unknown and dangerous.

Last but not least, it highlights the Internet speed and enables you to measure it right from within the interface.

Difference between System Mechanic Editions

System Mechanic Professional includes all features of System Mechanic. The software furthermore includes three iolo products that can be purchased separately. The products are System Shield Antivirus & AntiSpyware, DriveScrubber, and Search and Recover.

If you don't require those, you may purchase System Mechanic instead which offers all other tools described in the review.

System Mechanic Alternatives

You may want to try the following programs as alternatives:


System Mechanic Professional ships with a lot of tools, of which most can be quite useful. Some tools could be improved though. The software uninstaller for instance is not checking the system for leftovers after the installation. It also feels strange that a Good system status after resolving all quick scan issues is often changed to a lower level after running a deep scan.

Especially the one-click repair options are handy for users who experience issues on their PC that they want to resolve without diving deeper into the issue.

Most functionality is however also available in form of free programs albeit not as a single tool but multiple tools.

Users who want to try the software find a trial version at the official download site.

    The full quote is:

    “The content is not stored or seen by any human unless donated as part of the feedback mechanism.”

    How much time before that data collection and processing become consentless, like Microsoft likes to do ?

    “Another way you can help refine this feature is to donate your actual emails so we can analyze their contents and improve the quality of suggestions in the future.”


  2. DaveyK said on February 22, 2021 at 9:32 pm

    Am I the only one that wishes that MS would instead focus on fixing some of the more glaring issues with their software before implementing silly new gimmicks like this?

    Outlook still loves to hang for several seconds at a time if there’s any issue accessing a mailbox (particularly a problem if you have several mailboxes open, or if your VPN connection temporarily drops). Quite why the server processing seems to share the same thread as the UI is beyond me.

    I’m also sick of the recent bug in Outlook that won’t let you attach a document to an e-mail if it is open in another window. Thus forcing me to close the spreadsheet, attach it, then re-open it again. Weirdly, if it is in the “recent” list, it will attach without complaint.

    Add onto this the horrible, cluttered interface in Outlook these days (so much white space and other huge elements) that make e-mail navigation a pain on a small screen and I can’t help think that fixing basic issues like these and improving the accessibility of the programs should be a far higher priority than a feature which 99% of people will probably just disable.

      I want them to fix Windows 95. Instead, they flounder along with “upgrades” until they realize … oh, look: that “evolved” into an unfixable mess … lets “move on” to make a new shiny OS, and leave another bit of debris and more abandoned users in our wake.

    Good for people who can’t spell This feature could be very annoying.

  4. Matthew Brockway said on February 22, 2021 at 11:02 pm

    I will be turning this feature off, when it comes out for Word. I have been typing for decades, and know what I want. Having predictions come up regularly is a real pain and distraction. So I turn them off in email and on my iPhone and iPad.

    1. Jo said on August 9, 2021 at 5:34 pm

      I agree with Matthew B – after the latest Windows update, Word started doing this and it’s incredibly annoying. I can touch-type so I don’t need the predictions – it creates errors and slows me down.

  5. Anonymous said on February 23, 2021 at 12:36 am

    Thanks Martin. The suggestions were annoying and sometimes inappropriate. I told Microsoft about it. I wanted to disable the suggestions and now I have. Good information.

  6. Charlie said on February 23, 2021 at 2:44 pm

    I see the option in Outlook web and it is turned on, but I see no evidence of it actually working as I type a new email.

  7. neil said on February 24, 2021 at 10:25 am

    and fix the issue of search. search has been about the worst thing MS ever did in Outlook & since moving to the title bar has not improved and the fact default searches now are FROM: is bonkers /rant

  8. anonymous said on March 23, 2021 at 12:40 am

    this new feature is sh*t; it’s like a rearview camera (actually, its way worse, but the analogy is coming): the machines are taking over our need for intelligent thought.

    But honestly, MSFT really ought to run focus groups that include people who have ADHD or photosensitive epilepsy. For us, this attempt to help productivity only significantly decreases it.

    (It feels like we are all being treated to a dose of that brainwashing technique you see on the SyFi channel that involves a lot of flashing lights and images)

    the worst part about any of this: that our comments, reactions, suggestions, thoughts… are never actually heard or acknowledged by any of these tech companies who just shove new crap onto our corporate PCs and don’t think twice about end user experience.

    sorry y’all, rant over. for now.

  9. Anonymous said on June 5, 2021 at 7:00 pm

    I absolutely hate this feature. Thank you so much for the how-to to turn it off. Now that you pointed it out, I will know to check the tiny bar in the left corner, but I spent time I shouldn’t have had to trying to turn this feature off before finding your post.

    I think “features” like this should be opt-in, not opt out, or should be much easier to find to turn off. And I agree with the suggestions above – there are plenty of other issues Microsoft needs to fix before adding “helpers” like this. One that wasn’t mentioned above – terrible grammar in the suggested grammar fixes. As often as they’re right, they’re wrong. And the database programmers need to learn the use of apostrophes…. Thanks for the rant space. :)

  10. anonymous said on June 26, 2021 at 3:36 am

    Thank you for posting this where I could find it and use it after an MS Office update today.

    Sadly, this nonsense is the same thing I see my company implementing and me coding for them: window-dressing trinkets that are this year’s Christmas toys that everyone needs to be told that they want, while data-integrity code defects go un-addressed because no salesperson can make a commission off of us publishing their correction.

    Our society is evolving, and being run by a generation that learned to communicate in broken grammar on their smartphone while nursing a five-second attention span.
    They _want_ the machine to think for them. It is so much easier than thinking for one’s self.

    Abdication of personal responsibility.
    Corporate America is only too willing to step in, for a modest fee and your privacy.
    We aren’t going to get Microsoft or anybody else to stop. There’s far too much money to be made at it.

    As above, thanks for the rant space.
    We will survive this, somehow.

    So, Microsoft wants to use what we type to improve AI while charging me a hefty annual price for Office 365 subscriptions. Then someday AI will tell me what to see, think and do and its happening already. Someone needs to get a hold of the monster and put it back in the pit.

    How will they profit from improving AI?

    Thanks for this article, this behavior started on my machine yesterday no doubt a sneaky effect of an update. It was easy to fix using your instructions, but I suspect Word and Outlook are still “phoning home” everything I type even though the predictive text is shut off.

    They think we’re all stupid. They should be paying us.

  12. Tammi Naumann said on July 7, 2021 at 8:53 pm

    Thank you for the resourceful article! I looked for the status bar entry, but I couldn’t find it in the web version of Microsoft Word. What I did find, however, was Editor (between Dictate and Designer) above the opened document, and the option to disable suggested text was in there. Scroll down to Text Predictions and click the item’s “button” to turn this annoying feature off. I think Off should be default. I hate when developers set defaults for items they think I need. Adobe is another company that does that when people want or need to download the free or pro version of its Acrobat PDF Reader. I often tell my students to uncheck the boxes next to the McAfee antivirus and Chrome extension options before downloading the reader because they likely do not need them. I think these options should be unchecked by default. Let the consumers make up their own minds.

  13. Robert Cohn said on July 8, 2021 at 12:18 am

    Thanks so much for telling us how to disable this intrusive feature – predictive text! It’s like having a know-it-all teacher always looking over your shoulder. Very irritating!

    I can appreciate why some people would love this feature, and in some cases it makes sense where time is more critical. But it should not be the default.

  14. Bill said on July 8, 2021 at 11:11 pm

    Unfortunately, it seems to me that the programmers job is made simpler when the human conversation is simpler. Predictive text, if used, limits the conversation to a box only as big as a programmers imagination and literary ambition. I know a lot of programmers. Imagination is not their strong suit – no offense to creative programmers intended. Broadly speaking, to predict the manner in which I prefer to speak would require far more resources than they would ever allocate.

    If it were up to me they would go the opposite direction as a software company. I want a far simpler interface with basic editing function and attachments. Anything more than that is a distraction and I can honestly say, totally ignored and certainly a distraction making me wish I wasn’t on outlook.

    In the end, I disable nearly every “improvement” Microsoft offers, and check “metered connection” to prevent it’s downloads from happening in the middle of mastering a single for a customer. Of course that is not supposed to happen but we all know how real life works.

    Ill pay 5x what they are charging if they strip it down to an OS that works as a background product and doesn’t need the internet and isn’t of bloatware. That OS would be pure gold, worth every penny.

  15. Helen said on July 26, 2021 at 3:45 pm

    Grateful to have found out how to turn it off. If this is how good AI is supposed to be then we’re in worse trouble than I thought.

  16. Unca Alby said on August 5, 2021 at 12:33 am

    Microsoft, and they’re not the only ones guilty of this, need to stop “giving us nice things” without asking us *FIRST* whether we want it or not.

    I am sick to death of finding some new app running on my machine that I didn’t see before, didn’t ask for, and didn’t authorize. Then I look up on the web and it’s 15 steps to get rid of it. Christ, it wasn’t hardly ANY steps to get it!!

  17. David Scott said on September 25, 2021 at 7:09 pm

    A true annoyance. I couldn’t believe this feature when it appeared and after tolerating it for a few days I did a ‘net search for disabling it. I’m a writer by trade and living, and this is antithetical to creation, whether fiction or non. In my mind, it reflects the whole dumbing down of this generation – it can give someone the appearance of being articulate, only to discover that they are anything but upon first meeting (or interview). Beware.

  18. anon said on November 2, 2021 at 6:38 pm

    Thanks for the tip on how to turn it off, was the first hit when I looked it up. I’m not really willing to slow down and check what suggestions they offer me as someone who can type 115 wpm ?

  19. JoeF said on November 7, 2021 at 6:42 pm

    Predictive text has sprung up on the desktop version and this article does not address that version. There is no “Text Predictions” on the desktop version to turn on or off.

  20. L Harwood said on November 10, 2021 at 2:17 am

    I finally figured out how to turn it back off!! when it starts to add the prediction hover the mouse over the prediction and it will take you to ‘text prediction’ and you can deselect it.

    Why ANYONE would want this is a question that boggles the mind.

  21. L Harwood said on November 10, 2021 at 2:20 am

    It is VERY clear to me that every time the programmers have some lovely little hack they like, they are convinced ALL of us would like them. Not. I’m with what Bill said last July – I would pay a HUGE amount for a version of Word that would just stay the same and do what I want and that doesn’t have a bunch of bells and whistles that aren’t necessary. Please!!!!

  22. Bob Bailey said on November 25, 2021 at 8:10 pm

    Thank you!! I looked in vain in the too-full and too-many “Options” screens for a way to turn off this annoyance.

    I wish there was a Notepad-on-caffine mode — not the wannabe one-size-fits-all unstable multimedia-editor-on-crack mode that might change erratically from day to day.

    There are too many bells and whistles in Word. Remember WordPerfect? It behaved like traditional software: Do this until I tell you to do otherwise — and the current settings were visible in an optional “codes” pane. Instead, Word buries formatting, styles and who knows what else in the paragraph marker. If I want to change the format of something, it may presume to change all similar items in both directions in the document. Feh!!!

    Back to your excellent post: thank you for letting know how turn off this unwanted “help” from the presumptuous twenty-somethings at M$.

  23. Bob Bailey said on November 25, 2021 at 11:07 pm

    The status bar toggle removes the annoyance in the current document, but it may be baaaack in a new document.
    There is perhaps a more permanent way to dispose of this annoyance:
    In the “File” menu, choose “Options”
    Then in “Advanced” pane (listed at the left of the options), navigate to the “Editing options” section.
    In that long list of micro-text, uncheck the box “Show text predications while typing.”
    My hope is that this will get rid of “just one of the intrusive PITAs.”
    The navigation above is for Word in Microsoft 365 Apps running on a desktop machine.
    YMMV in other versions, and these instructions may be broken when M$ spews another “upgrade” of the version I am using on this machine.

  24. Chris O'Leary said on January 31, 2022 at 12:41 pm

    Just noticed this was turned on, presumably by business IT admin. It’s atrocious, not at all usable, like Google’s is. Instead of accepting my typed words, it refused to allow me to add a space between words as I typed, instead waiting for me to accept or reject the suggested words. So unintuitive it’s not funny. Turned it off immediately.

  25. mcswell said on April 12, 2022 at 1:12 am

    You need to *right* click on the thingy in the status bar; left click brings up the Options dialog, and if this predictive typing thing is on the options dlg, I sure can’t find it. Right click brings up a long, unorganized (afaict) list of options that you can check or un-check, and somewhere in that long list is predictive typing.

    I’m not sure how you’d turn predictive completion back on if you decided you want it, but that’s someone else’s problem.

    Now if they’d only fix automatic number, which has been broken in every version of Word I’ve ever used.

  26. J. Typing Efficiency said on April 10, 2023 at 4:13 pm

    The abruptness of it popping up and diverting my attention from my flow of thoughts is very distracting. I tried it for a short while and quickly decided it was slowing me down, making me stutter in my thoughts, and just generally getting in my way. I type plenty fast on a PC. Now on current phones with screen typing that is slow and prone to typos, yeah, you might want some predictive stuff to survive there. But I still do not want anybody snooping my info, so there is that.

    I have had LibreOffice 7.6 for over a week. The only fault that I can find is that the help function still does not work in Ubuntu. It tries to find a web page that does not exist. This occurs in both the menu function of help and pressing F1.
    I found this in earlier versions of 7.x, and reported it, but was brushed off.
    I think it works in Windows, but I am not sure.

    LibreOffice is great. Some of our customers are still using outdated MS Office versions. With there okay, we install it and set the saved file formats to MS, Writer font as Calibri. About 90% still use it years later. The ones that don’t typically require Microsoft 365 for work.

    Notepad2 is all I find myself using these days.

    1. Anonymous said on August 22, 2023 at 11:19 am

      Notepad ? Why don’t you use Vi ? (well or Vim if necessary)
      Notepad as nearly as terrible and unnecessarily feature-bloated as Emacs.

      But if you are truly hardcore, you’d use ed or edlin and nothing else.

      1. Anonymous said on August 23, 2023 at 12:36 pm

        No, not Notepad, Notepad2, which is a completely different application. On top of that Notepad2 is a Windows only application, so mentioning Linux text editors like Vi(m), Emacs, ed and edlin does not really make sense.

  33. Scyld said on August 22, 2023 at 9:06 am

    In the past I didn’t like LibreIffice but after they improved a few things in 7.4 and 7.5 I actually like it and use it. Mostly Writer. In terms of features it is much better than any other software of this kind except MS Office. In terms of customization it seems the best. Guys who prefer minimalism may use OnlyOffice, but work is way more comfortable and productive in LibreOffice. As for questionable improvements, Libre gets them but as long as I can turn new features off I don’t really mind.
