Free Process Lasso Pro!

Software Description

The following is the description of Process Lasso Pro as per the developer:

Process Lasso is a unique new technology that will improve your PC’s responsiveness and stability during periods of high CPU load. Windows, by design, allows programs to monopolize your CPU without restraint — leading to freezes, hangs, and micro-lags. Process Lasso’s ProBalance (Process Balance) technology intelligently adjusts the priorities of running programs so that badly behaved processes won’t negatively impact the responsiveness of your PC.

Process Lasso also offers an assortment of ways to take full control of how your CPUs are allocated to running programs. In essence, it is an all-in-one automated Windows process tuner. You can choose at what priority processes should run, and which CPUs should be assigned to them. You can also disallow certain programs from running, log all programs run, automatically restart programs, limit the number of instances of a program, and much more. You can even indicate processes that should induce entrance into the High Performance power scheme or prevent the PC from sleeping. A gaming mode also allows for easy process priority optimization for avid gamers.


  • ProBalance
    • Balance process priorities (or CPU affinities) in a safe, effective manner to improve PC responsiveness during high loads and prevent system stalls and micro-lags. Our technology does NOT do additional foreground boosting, instead it lowers background process priorities where appropriate. Our years of experience have resulted in a highly optimal algorithm duplicated nowhere.
  • Automated Process Control
    • Set default priorities and CPU affinities, disallow processes from running, and log events on your system
  • Power Scheme Automation
    • Set the power scheme to automatically change to ‘High Performance’ when certain processes are running, then change back when they exit
  • Process Watchdog (in v4 only)

    • Terminate, restart, or change CPU affinity when a specified threshold is met
  • Instance Count Limit
    • Limit processes to a specified number of instances
  • Multi-Core Optimization
    • Through default CPU affinities and ProBalance affinity adjustments, you can optimize your multi-core processor to make the most efficient use of your CPUs (cores)
  • No System Registry Values Changed
    • Process Lasso makes NO registry or system setting changes. It does have advanced tools that will enable YOU to make changes if you choose, but we generally do not recommend it (and say so in warnings). Note Process Lasso does store some of its own data in the registry, and we are speaking only of system registry values.
  • Independent Core Engine
    • This stand-alone background process can run as a normal process or as a service. This ‘core engine’, named ProcessGovernor.exe, is what actually enforces process rules and ProBalance. It doesn’t need the presence of the GUI (main window) at all. This allows for minimal resource utilization.
  • Minimal Resource Use
    • NOBODY uses less resources for this type of task than Process Lasso. It is written in native C++ and continually refined for maximum efficiency. A native 64-bit build also available. Private memory usage by the core engine is typically under 1MB! (depends on system)
  • Utilizes new features of Windows Vista/7
    • Makes use of latest features of Windows 7, but maintains full backwards compatibility to Windows 2000!
  • So much more…
    • Discover for yourself what Process Lasso can do for yourself

dotTech Advice

Back in September Process Lasso Pro was featured on GOTD and  I wrote a rapid review on it; the final verdict in that review depicts exactly how I feel about this program:

Process Lasso Pro is not meant to make your computer super faster. If you have a Pentium III and you expect Process Lasso Pro to turn it into a quad-core, you will be very disappointed. Process Lasso Pro is intended to help you manage your CPU in the most efficient way possible, preventing rogue CPU usage from causing problems. In that regard, Process Lasso Pro performs extremely well; Process Lasso Pro is a terrific program. I especially like the extra functionality the developer has built-in that goes beyond just rogue-CPU-usage-management. I give Process Lasso Pro two thumbs up and highly recommend it to anyone. […]

If you missed Process Lasso Pro in September this is your chance to get it. If you got Process Lasso Pro in September, this giveaway is of a slightly older version than the GOTD giveaway (v3.80.2 vs v3.84.7) so you don’t need to upgrade. However, you may want to consider the following: Process Lasso Pro from GOTD cannot be reinstalled; Process Lasso Pro from this giveaway might be able to be reinstalled. I don’t know this for sure, though, so don’t quote me.

Freebie Details

Before I tell you how to get Process Lasso Pro for free, let me forewarn of something because I know it may confuse some people. During installation of Process Lasso via this giveaway, the program is calling itself “Process Lasso Special Edition”. As far as I can tell “Process Lasso Special Edition” is the exact same thing as Process Lasso Pro, hence why I am calling this a giveaway of Process Lasso Pro. Plus, the installer may call the program “Process Lasso Special Edition” but the registration confirmation page calls its Process Lasso Pro.

That said, to get Process Lasso Pro for free, follow these simple directions:

Version being given out for free: v3.80.2

Free updates: Probably not

Supported OS: Windows 2000 and higher

Download size: 2.1 MB

If you do it properly you should get a message similar to the following:

  • Check the inbox of the e-mail address you registered with. Look for an e-mail from with the subject of Newsletter: Bestätigung. In the e-mail there will be a link you need to follow to confirm your registration:

Click on the link and you should be shown the activation code you need to use with Process Lasso Pro:

  • After the download has finished, unzip the file, and install Process Lasso Pro. (The installer and program are in English.) Take note that both 32-bit and 64-bit versions of Process Lasso Pro come in the download, so be sure to pick the correct one for your computer. Also note that there will be two files present: CPUEaterDemo32.exe and ProcessLasso-32-Bit-Setup.exe (or CPUEaterDemo64.exe and ProcessLasso-64-Bit-Setup.exe, if you are installing the 64-bit version). You only need to run ProcessLasso-32-Bit-Setup.exe/ProcessLasso-64-Bit-Setup.exe – the other program is just a demo program to help demonstrate the capabilities of Process Lasso Pro.
  • After installation has finished, run Process Lasso Pro and register it with the activation code you received earlier:

  • Enjoy!

    I have the free version from Giveawayoftheday and like it. I let it run with the default settings and all I change is exclude my anti-virus from restraint.
    The only problem I have had was when I did a reformat I lost the program.
    I would like program makers to find a way for people to either save activated programs or give us a way to pay for programs that does NOT involve using a computer to do so.
    There are a lot of people that never do any financial transactions on their computers, I’m one and I would never let my kids computers do it either.
    I find it to be an excellent program and one that I would be happy to pay for if there was a way to do so without online banking. I won’t use PayPal after they stuck it to Wikileaks either.

    GAoTD recently offered version 4.00.30 so my installation concerns in comment #32 is no longer an issue. All good things come to those who sit and wait, but I will purchase Lasso when I really see its true benefit (right now, it just appears to be a more sophisticated Task Manager but I really haven’t explored its’ full potential). Is there a comparison of Lasso to Win Task Mgr available?

  • Neil from Ohio

    On the website you will find a detailed comparison of the “free” and “pro” versions.

    Process Lasso is starting at STARTUP even though I requested it not to do so. My request is not saved, so short of removing it from my PC, how may I prevent it form starting? Also, is there a matrix describing what version 4 features will be disabled after the trial?
    Also, where may I obtain freebie version 3.8 so I may apply the ALPHA4-BETA16-GAMMA2 code?

  • Ashraf

    @Jeremy Collake: As someone I know likes to say, all is well that ends well. While I am sure there are ways this situation could have ended better, all is still well. I appreciate your comments and do apologize for any problems dotTech may have caused you.

  • I would like to say that I believe the author’s intentions here were pure. The problem arose when other sites picked up the errant ‘free v4’ discovery that lasted a few hours. So, this site is good, and although this old give-away and old key took me by surprise, I do not begrudge this site or the OP in any way.

    Please understand, authorizing my German reseller to do a limited magazine based give-away of a version some months ago is a big difference from authorizing everyone on the internet to get Process Lasso Pro v3 for free. However, since time has passed, it now doesn’t really matter. If users want the old version, they can have it ;).

    I certainly apologize I initially didn’t know what was going on and it took a bit of time to fully understand the situation. If you read this far, you might find the key active indefinitely for v3, who knows ;)

  • Hi guys, I am the author of Process Lasso. The announcement of this old private give-away caught me by surprise. It was a give-away of version 3 (only) by my German Reseller to PC Praxis readers (only). A special edition was even created for it. It occurred many months ago (I don’t know when exactly, but a long time ago).

    Sadly, my activation system was acting quite liberally. It allowed the STATIC key you get at the German reseller site (ALPHA4-BETA16-GAMMA2) to activate the standard edition. Yes, it is a static key, so no need to sign up.

    Later, it was discovered that it even allowed v4 to be activated. Now this was a surprise. I fixed it quickly, and those few who did activate be fore-warned that future updates may deactivate you.

    This morning there was a problem with our activation server. The current state is that version 3 is being given away using this code. I could disable it, as it is not really an authorized give-away. However, if you guys choose to use it, there it is ;).

    This key, however, is not valid for v4. I have to support my family, etc… So I can’t give it all away. This is the only mistake that (now) needs corrected. Since the activation system errors were my own (I chose being liberal over being strict), I will continue to allow this for at least the next few days. At some point, I’ll likely kill the key though.

  • a simple happy man

    By the way let’s make it absolutely clear here that the website that is referred to in the developers explanation is not Not NOT

    This whole story has absolutely nothing to do with or Ashraf in anyway what so ever.

    As we all know very well there are plenty of websites out there that do not come any way close to having the same high standards , principles and ethics that Ashraf has instilled into dottech and it is one of these that the developer refers to.

    And that’s the end of the story for me too! Time for bed said Zebedee

  • a simple happy man

    @Clodmore: @Rob:

    Hi all

    The developer has put together an explanation of what has happened and suggests that people who cannot activate the giveaway get the free version 4 from his site. No nag screens and indefinite use.

    Anyway here’s the ‘story’ url for whoever wants to check it out.

  • a simple happy man

    @Rob: @Clodmore:

    I am sorry but I can’t help you there !

    I’ve looked on the Bitsum site and loads of download sites and they are all version 4 now.

    The PC Praxis (unauthorized) giveaway was (reading the rules of the german giveaway) only supposed to be for 24hrs anyway but developers/suppliers tend to leave the giveaways up until after Christmas but I guess if the link for this giveaways v3.8 was on the developers site then its been changed to v4 now!

  • Rob


    @a simple happy man:

    OK. I have to ask the same question I previously asked (in post 35, question #1). Is there a specific link to download the previous version from? The email directions I have point to 3.8 but then provides a download link for version 4. Just to muddy the waters…… (link shows 3.8 but then goes to a link for version 4.) (clicking on the download link here also points to version 4)

    Thanks, Rob

  • Clodmore

    @Rob: Yes, that seems to be the serial number, at least that is the one I used. I installed version 3.80.2, which I had downloaded from the German site, IIRC. Now whether the installation works in 14 days, I guess I’ll find out. BTW, I used RevoUninstaller to uninstall version 4.02.

    Good luck!

  • Clodmore

    @a simple happy man: Thanks for the information. After realizing, with Ashraf’s help, that the license was only meant for 3.8, I was feeling bad. With your information, I deleted version 4.02 on both machines and went back and installed version 3.8 without any problems. I feel much better now! Thanks.

  • Rob

    @a simple happy man:

    Appreciate the follow up and the explanation. However I’m about ready to throw in the towel on this one. If anyone is pursuing this software here are some questions I’m sure others have that will help us all.

    1) Is there a specific link to download the previous version from? I’ve yet to find an older version at either site.

    2) Should we download version 3 or 3.8? They have been used synonymously in previous posts, including the most recent, #34.

    3) Is the activation key the same one first published (ALPHA4-BETA16-GAMMA2) or has it changed? (Would not have posted the key but it was already mentioned earlier).

    Sounds like this offer has been a bust all the way around. Apologies to Bitsum Technologies. Any further clarification is appreciated.

  • a simple happy man

    Hi Ashraf and all

    This is a heads up for all dotTechies about this giveaway.

    I heard that the serial number for this giveaway application v3.8 could be used to upgrade to v4, so I did it and it worked!


    Shortly afterwards I kept getting the request to re register the program, but it wouldn’t re register.

    So I contacted Bitsum Technologies who replied that the original giveaway by PC PRAXIS.DE on their advent calendar had not been authorised by them (BITSUM)
    and that they had not given permission for SOFTWARE BUTLER to host the giveaway of the license key either
    and therefore BITSUM TECHNOLOGIES cannot support the giveaway or give any free support to it or updates or upgrades either.

    However because the developer of Process Lasso JEREMY COLLAKE is a nice guy he has said the following (and I quote):

    “The give-away where you found that key was unauthorized.
    They sent people to my German reseller to sign up for their newsletter, then gave them that old v3 key.
    I do not know what to say except that NOBODY authorized that give-away.
    That site did it on its own.
    I’ve ‘let it slide’ , but I can not support the unauthorized give-away.
    I was shocked to find out about it myself when I started getting emails similar to yours

    The v3 key may or may not work (now).
    I discovered a larger problem with the activation system that persisted for the last 10 hours. However, the v3 activation system was different than the v4 activation system.
    It likely works now, but I won’t guarantee that.

    I figure, at this point, it is best to just let people have this give-away of version 3 (the old version). I’m happy to give away version 3 if people want the older version for some reason. So, I recommend only correcting them to say it is ONLY for version 3 – not the new version 4”

    So the crux of it is that although the giveaway was not authorised the developer is letting it go ahead with absolutely no guarantees that the serial number will work, and if it does work no guarantees as to how long for, plus there will be no support at all for the giveaway serial number and no updates and no upgrades.

    So if you’ve got it and it works, all well and good as long as you stick with v3.8 but if it stops working you either have to fix it yourself or the developer suggests you can do the following:

    (from the developer):

    1. Forget the German site, that is my German reseller and they aren’t as a nice as me ;)

    2. Download Process Lasso free edition.
    It is entirely free to use indefinitely except that some advanced features will disable after 14 days. You’ll also see a small little dialog at startup (only) and you click past it with one click.
    So, give it a try… If you like it, keep using it, or upgrade to the Pro version to help support my small company.

    Well that is it!
    If you’ve got it do NOT upgrade to v4 because that is how it gets disabled, stick with v3.8

    All the best to everyone and Happy Holidays everywhere!

  • mukhi

    this program is good, however, for people like me who don’t really need to control the use of CPU, it is useless. uninstalled.

  • dan

    Chuck (#31),
    Ashraf (#30):

    Appreciate your suggestions (and sympathies) but whereas Lasso is a nice utility I can’t say I relied on it heavily since I never delved into its full capabilities. So I won’t do a restore but just wait for it to be re-offered here or on GAOTD. Meanwhile, version 4.00.27 doesn’t show any expiration date so I assume I’ll be running with less functionality sometime in the near future…oh well!

    Thanks for sharing your thoughts.

  • chuck

    Dan-if you’re saying that you are now without a registered version,System Restore may set things right-Got nothing to lose,right?? Or…if you tucked away your original Reg code (the program doesn’t display it),you could go the Revo route,reinstall with your original .exe file (if you saved it) then re-activate.Should leave you with whatever time you had remaining on that license.Best of luck,and Merry Christmas!!

  • Ashraf

    @dan: I would have gladly posted the deadline if I knew about it. I don’t always have full details about promotions that are not run by dotTech. Sorry.

  • robertmc8

    This promo was great. I just got free updated to v4.0.28 Looks like it was one day promo. This why I check this site daily :). Tell Person who own this program big thankyou :). I wish I can donate but I don’t have charge card.

  • Dear A.S., in regard to your question about O&O Clever Cache and Process Lasso Pro, they are completely different types of software and I have never seen a conflict between them. O&O Clever Cache tries to optimize your memory usage and cache usage whereas Process Lasso Pro looks at individual processes and keep them in check if anyone tries to hog all the processor time. The newer versions do much more than this but essentially they will coexist with no issues.

  • dan

    Based on Chuck’s reply (#26) looks like my former Lasso freebie license is now no good with the new release install. Sure wish this site had posted a 12/15 deadline warning.

  • chuck

    Looks as though the offer was good for 12/15 only,as I got the “code failed” error when trying to install on this lappy yesterday.I revisited the promo site (Software Butler) to try again and it said “This download was unfortunately only on 15 December for you” Anyone think I could run the .exe from another version on another comp. and make this happen??

  • A. S.


    How does this compare to O&O Clever Cache, that I think was a dotTech Freebie some time ago? Are the programs’ processes similar and would both programs conflict if used together?


  • Rob

    I can’t seen to register this program. When downloading the website only provides version 4. I don’t know if the registration number I received is for 3.8 and that’s the reason or not. I’d like some help with this if anyone has any ideas.

    The other difference I see is that the example / screen shot here shows 3 columns to enter the registration info. in and version 4 only prompts with 1 column. Have tried with and without hyphens and spaces but still no luck. Also double checked that the program plActivation.exe has full access with McAfee so there shouldn’t be a problem there. Any ideas or help or a working GOTD registration number is appreciated.

  • dan

    Forget my comment #22; now I get an ACTIVATION FAILED! message when using code ALPHA4-BETA16-GAMMA2.

  • dan

    When I click on the download all I see is a page of 4 quadrants displaying a snow scene and a 10 second count-down that repeats endlessly. I’ll try later but if no luck I’ll assume the download offer expired.


    THANK U!

  • Eva

    @aqua: If you post that message here, someone who knows German might be able to tell you what it means.

  • aqua

    the link is there but it takes to a red german message

  • J . L.

    Thanks for posting this giveaway!

  • Ashraf

    @Everyone: You are welcome, but my intention was not to show everyone that you could upgrade to v4 for free. Heck, I didn’t even know; and even if I did know I probably still would not have mentioned the free upgrade to v4 because it I don’t believe it is officially supported (darn clean blog policy). My intention was to inform people of v3.80.2 being available for free. I am not sure if the free upgrade to v4 is officially supported or not, but you may want to consider making a small donation to the developer if you upgrade, especially considering how he already provides a freeware version.

  • Elric

    I am unsure about this as I downloaded the GOTD version and ended up removing it from my old computer because it seemed to slow it down. And all I did was use it’s default settings. So am not sure I want to try it now on this computer (different computer this time with a dual core)

  • Al Hall

    Sweet! I just went to the German website and retreived the reg code, then went to Bitsum and downloaded the latest (4.00.27) version. Expanded the zip and was confronted with “ProcessLassoSetup.exe” and “QuickUpgrade.exe”.

    Since I already had version 3.84.7 running [I guess from GOTD] I decided to try the QuickUpgrade.exe.

    Instantly, the thing tells me that I’m upgraded to v4.00.27 pro and suggests that I should re-start the program… Viola, upgraded to 4.00.27Pro just like that!

    Thanks, Ashraf. I really like this program!

  • Clodmore

    Thanks everyone for the tips! I had the GAOTD on both of my computers. I installed 4.00.27 and entered the registration code received today and it works! Nice to have the latest version on my system.

    And thanks, Ashraf, (I think I finally spelled your name right this time), for bringing this offer to our attention.

  • Jimmy

    Thank you Ashraf for the info and for the GiveAway

  • Spredo

    And as Mike says, the activation code for this giveaway works for the latest version as well.

  • Spredo

    Does this work the same way the GAOTD-version does, i.e. if you scan your computer with any kind of registry-fixer, Process Lasso shows up as “outdated” and “wrong” and should be “fixed”?

    I have the GAOTD-version, so I have no reason to install this. But if you DO install this, be aware of the “registry repair” problem that MIGHT appear.

  • Mike

    Great software, thanks Ashraf. Just a point … I downloaded the older version of Process Lasso (v3.80.2) then read the comments about the key working for the GOTD version. So, I just pressed the update button and it took me to Process Lasso’s main site where I downloaded version 4. You can imagine my surprise to discover that the same key also works for the very latest version (v4.00.26).

  • Eva

    Thanks for the pointer! I had an older giveaway version of this installed on my old computer and had been idly looking for it for my new one.

    A small addition: According to the text on the site and in the email, one does sign up for a newsletter from the site by entering one’s information and later confirming the email address.

    If the site does things correctly, any newsletter later received should of course contain an “unsubscribe” link. But for those who don’t want to wait, or who don’t know German and wouldn’t find handling the email easy, there’s a fix:

    One you have the license code, return to the page from which you registered for the site. There, fill in your information again, but make sure to select “Abmelden” (unsubscribe) rather than “Anmelden” (subscribe). You will then receive an email with the subject line “Newsletter: Abmeldung”; click the link in that email, and the site claims that you have been unregistered for the newsletter. The site is really not clear, though, as it still says together with that confirmation that you will receive your license key for Process Lasso once you have registered successfully. Quite sloppy.

  • Do Do Re

    I use version 3.99.17 beta(32 biti) from a time.Everythink work super.

  • Sambo

    I initially registered using my real country but didn’t get an email, so I registered again, but this time left the default ‘Deutschland’ in the country field and received an email immediately… I also used a different email address the second time but I’m not sure if that helped or not.

  • robertmc8

    PCbasics Ya this older version. If you formated you can used this new key with old 3.84.7 version from GOTD :)

  • wait, so this is a different version from the previous GOTD, right?

  • robertmc8

    @Ashraf Ya I’m just glad Old GOTD from 3.84.7 works with this new promo key older software it’s strange. If anyone has on there backup hard drive now time redeploy it. While you got chance. If you have fresh formated harddrive:).

  • Ashraf

    @chnkk: Works just fine for me. If you are having trouble, skip that part and download Process Lasso Pro. After you install it, you will be asked to register it – there will be a button that allows you to access the registration page.

  • Ashraf

    @robertmc8: I guess the developer must not have disabled the activation of the GOTD key.

  • robertmc8

    hehe I used old pro giveaway software 3.84.7 it works great :D thanks With new key works well :) So if you had reformated you can used your old 3.84.7 software key works fine.
