Perfect Utilities is an excellent freeware system maintenance/optimization software… because it is a copy of WinUtilities!

UPDATE2: It seems like the developer of Perfect Utilities is no longer providing it freeware. Anyone that tries to download Perfect Utilities will get WinUtilities ($49.95)!

UPDATE1 – WARNING: Since I reviewed Perfect Utilities, the developer has made update to the software. The latest update, v3.03 comes with Relevant Knowledge, known malware. So if you are going to get Perfect Utilities, I suggest you grab v3.02 until the developer releases a “clean” version of v3.03.

There are many excellent commercial system maintenance/optimization software out there on the market right now. In this list of excellent commercial system maintenance/optimization software WinUtilities is highly regarded as being near the top, i.e. it is one of the best. Now WinUtilities is one of dotTech’s exclusive freebie and it is continuously given out on Giveaway of the Day so to say you always have to purchase WinUtilities to get it is an understatement. However WinUtilities is still in fact commercial and costs $50 per license. So when I found out there is a freeware copy of WinUtilities I was reluctant (suspecting some foul play) at first but overjoyed after wards.

Perfect Utilities is a new system maintenance/optimization software and it turns out that it is an exact copy of WinUtilities. How do I know this you ask?

  • The interfaces are uncannily similar:

  • When installing Perfect Utilities (v2.0) you will see that it extracts a file named “WinUtil.exe”:

Just the name of the file is a dead giveaway but to further pile on the proof, when installing WinUtilities (v7.0), the same “WinUtil.exe” is extracted:

  • I first installed Perfect Utilities v2.0 then I installed WinUtilities v7.0. Perfect Utilities wanted to install into C:\Program Files\Perfect Utilities so I let it. Ironically, WinUtilities also wanted to install into C:\Program files\Perfect Utilities:

  • When trying to run WinUtilities (v7.0) while Perfect Utilities (v2.0) is already running I get the following error message:

2009-08-13_113433

  • Lastly, here is the kicker and dead giveaway number 2. Perfect Utilities is developed by “YiLong Software” while WinUtilities is also developed by “YiLong Software”:

Now to say they are exact copies (like I said earlier) is a not 100% true. WinUtilities uses up ~30 MB disk space while Perfect Utilities uses up ~20 MB. Notably WinUtilities has a file called WO.exe, a file commonly mistaken for a virus, while Perfect Utilities does not. However both programs have the same features and perform the same so I really don’t care what is going on behind the scenes.

Update: Upon further investigation, after some dotTechies expressed some concern, I learned a few things by doing multiple clean installs of both programs.

  1. WO.exe is not a part of WinUtilities anymore. WO.exe was a left over file from previous versions of WinUtilities that I had installed. WO.exe used to be the main executable for WinUtilities. Now WinUtil.exe is… just like it is for Perfect Utilities.
  2. The reason for the ~10 MB difference in disk space usage between the two programs is because the “skins” folder is WinUtilities is ~10 MB larger than the “skins” folder for Perfect Utilities. In other words the only difference between WinUtilities and Perfect Utilities is that WinUtilities has more skins to choose from.

Okay so Perfect Utilities = WinUtilities (as far as I can tell v2.0 = v7.0). So what you ask? Why is Perfect Utilities an “excellent system maintenance/optimization software”? Well because it carries the features and reliability of WinUtilities without the price tag:

The features listed above are as of v2.00; new features may be added in future versions.

Come on – you have to admit you are impressed. I know I definitely am. Why ever pay for a system maintenance/optimization software when you can get Perfect Utilities for free. Perfect Utilities is an excellent program. You can download Perfect Utilities from the following link:

Perfect Utilities works on 32-bit and 64-bit versions of Windows 2000/XP/Vista/7

Thanks Jeff!

Disclaimer: No matter how good a system maintenance/optimization program is none of them are perfect. Please be conservative when cleaning out your registry, duplicate files, junk files, etc. Always make a backup first before doing anything (Perfect Utilities should automatically create a “rescue” point but just double check it via “Options” for each module to make sure the “rescue” point is turned on).

    To avoid RK when installing PU 3.03, don’t press “Accept” button, just press “Decline” and it will continue installing without RK. Don’t forget to press “Decline” for second time when RK pops up.

    I have version 3.02 but every time I open the program a message pops up saying a new update is available(3.03). The thing is, I turned off the automatic updating in the options menu, so, what the heck? is it only me?

    @Scott: Did you read my “update”?

    UPDATE – WARNING: Since I reviewed Perfect Utilities, the developer has made update to the software. The latest update, v3.03 comes with Relevant Knowledge, known malware.

    Hi Ashraf,
    First up, thank you for your excellent reviews. I just wanted to draw attention to the Perfect Utilities forum. Users are having installation problems with PP but nobody has actually said which version they downloaded. Since your review was based on v2 I am guessing that they have been trying to install v3.01; you may like to have a look at this yourself before publishing any comment on this topic.
    Best regards
    Bryan

    Ashraf you talk about a lot of programs that do not have self executing registry back ups but i don’t think you have identified many programs that do and what about other types of backups that self execute ??? How many are there that are worth using ? Do they need a mechanic to work them ?

    @cham77: I downloaded v7.0 right off the developer’s website to test before making this post and I can assure you WinUtil.exe is there instead of WO.exe now. The developer may have made that change after releasing it on GOTD.

    @cham77: The “~” means about; in other words the “10 MB difference” is a rounded number. The only other difference I found besides the skins folder is WinUtilities has these 1 KB .exe.manifest files for each tool which Perfect Utilities does not. The .exe.manifest files are developer created files related to running software on Vista so they don’t really impact the program functionality therefore I did not want to confuse everyone by mentioning them. I am not sure why Perfect Utilities does not have them while WinUtilities does considering Perfect Utilities works on Vista (an experienced developer is welcome to help answer this question).

    Also, the skins folder of WinUtilities 7.0 is only 9.45 MB (9,919,032 bytes) total so how can your following statement be true?

    “The reason for the ~10 MB difference in disk space usage between the two programs is because the “skins” folder is WinUtilities is ~10 MB larger than the “skins” folder for Perfect Utilities.”

  9. cham77

    I have WinUtilities 7.0 from GOTD, the executable is wo.exe not WinUtil.exe, WinUtil.exe is not on my computer at all. The file version of wo.exe is listed as 7.0. I am using win xp 32bit. Also the default install path is C:\Program Files\WinUtilities not C:\Program files\Perfect Utilities

  10. TheCuzKev

    Yep Ashraf You are so totally right…I just took 7.0 WinUtilities off and put this free verson on and they are exactly the same…Wow what a great find…TY so very much….And yep I checked it with McAfee and ThreatFire and Perfect Utilities setup is Perfectly Clean lol :o

  11. surfriot

    Yes, Ashraf, I did have WU installed when I installed PU….I’ve since uninstalled WU after reading what you wrote about uninstalling it. What I’ll do now is uninstall PU and reinstall. That should resolve it.

    @surfriot: That is weird. Mine says “21.9 MB”. You may have previous version of WinUtilities installed? Since PU and WU are the same program, Windows confuses them sometimes it seems. Or if you have used Perfect Utilities excessively, the ~40 MB may be of backups that were created by Perfect Utilities.

    @hahaguy: I would have preferred for you to just link back here instead of posting the differences and similarities because people may source that blog post instead of my post for the find if they copy but technically it is released under a CC license so it is okay with me =).

  14. hahaguy

    Great find. Personally I don’t really use winUtilities but still it’s good for those who might have lost WinUtilities 7 given away by GOTD.

    Since I liked this post so much, I decided to ‘share’ this with others on Raymond’s forum. Hope you don’t mind. You can see the post here (safeguy and hahaguy is the same person, fyi):

    @J. L.: Oh okay. I thought you meant some other sort of program. No I have not tried a duplicate file finder for this because those programs are horribly inaccurate. I am satisfied with my proof that this is in fact WinUtilities rebranded and a safe file. You can, however, run a duplicate file finder for yourself and let us know.

    Author/Mr. Boss

    @J. L.: That is because the website is very new. It was created on August 4th. I checked the download file w/ VirusTotal and Avira – it is clean. However I am not sure what you mean by “duplicate finder program”? Never really heard of, nor used, one of them. Are you talking about a “duplicate file finder”?

    @surfriot: You are welcome.

  17. surfriot

    I guess if you trust this then we can’t go wrong, WinUtilities is great, although I think the registry cleaner has messed up my computer a few times. Thanks Ashraf, and for the heads up on the Online Armour, that was excellent!

  18. J. L.

    Not sure about this, the website is unknown to LinkExtend Safety (which includes: Web of Trust, McAfee SiteAdvisor, Web Security Guard, Browser Defender, Norton Safe Web, DrWeb, Compete, Google Safe Browsing.
    VirusTotal did not detect anything though.
    Have you checked it along with WinUtilities using a duplicate finder program?

    @Kinetix: They may plan on releasing new WinUtilities with newer features. Kind of like how Glary Utilities does it with the freeware having less features/support than the commercial one.

    Or maybe they did not get enough revenue via WinUtilities so thought a freeware might bring in a lot of donations.
