    The latest version of Vipre, my antivirus / firewall program says, when I ry to download this, that it's a trojan and blocks it. Funny, I have the earlier version of this, and it's not an issue....

    Why would you need to change the key?

    Reviewing (Sep 21, 2012)

    yes it can be done. there are other, more difficult ways, but windows keys can be changed... if you're an admin, and you have to do multiple installs (upgrades) then imaging is the best method... once all are imaged you can then change the keys to match what the box tag says if you're not using VLK. (volume licensing keys)

    @-Lord-, can that be done? (Was under the impression that with later -XP- versions, that a changed key reverted back after reboot?)

    Does the older 1.5.1 Keyfinder still work?

    Does RockXP work?

    They still have not put the capability back to allow you to change Windows keys. My previous review stands.

    App worked great. Migrating Visio 2007 I realized I had no install media and key for Visio 2007 for a client. I re-downloaded Visio 2007 trial from Microsoft's site and used this on the old system and it worked wonderfully.

    As soon as the functionality is restored to be able to change keys (Windows) I will rate this higher. It's normally a great program, but as an admin, I use this routinely to properly register ghosted machines with their proper keys (off their sticker) to remain in software compliance.

    Fix it, please.

    Reviewing 2.0 Beta 2½ (Dec 2, 2006)

    Does exactly what it claims. If you want to get your product key for Windows or Office it does not get an easier.

    This is not a tool for administrators on networks. It makes no claim to be used in this manner and evaluating something based on what it does not do or claim is ridiculous.

    An excellent utility.

    Excellent tool for personal use.

    However, large company administrators still use their own scripts to mass update or change keys, or remote copy keys. They don't trust such apps. :(

    Program does what it says but why would you want such a singular program when other free programs can give you more information about your system besides "just" keys ie: Belarc Advisor.

    Reviewing 2.0 Beta 2 (Nov 1, 2006)

    Only beef I have with this is it says it gets keys for ".NET" but .NET doesn't require a product key.

    Unless it means Visual Studio .NET, in which case it is seriously lacking because it is unable to detect Visual C#, C++, or VB .NET 2005 Express Edition.

    However it correctly found my XP and Office 2007 keys. And it has the ability to be assigned new registry keys to check for new product keys... could be nice if the devs add some more third-party programs to that area.

    Reviewing 1.51 (Aug 9, 2006)

    It does not surprise me that something from Sonicwall would give a false positive. Before posting rants here about some file being a "Trojan" you need to be more responsible and first submit the file to various reputable AV companies for confirmation such as Trend Micro, Kaspersky ect... then if they tell you it is infected with something, then post it. If everyone did these knee jerk reactions everytime their AV gave a false positive, every software author at some point will be accused of this. This file is clean.

    It also does not surprise me Windows One Care would flag this as malicious since this program does pull Product Keys from Microsoft Products. Microsoft is obviously against such things since they assume more people do this for the wrong reasons. It is still an overreaction to scare people from using the program.

    Does what it says.

    Not a Trojan because this software does nothing else that it says : retriving CD-Keys.

    But I agree it's a risky app in a corporate environment ;)

    BTW : RockXP does this kind of thing plus more for ages that's why I gave 4 instead of 5 :D

    awesome program--can't tell you how many times I have had to reinstall other people's systems and they've misplaced their CD-KEYS keys (stick them on the case, people!)

    In victor's defense, Windows Onecare (big surprise) does report it as a trojan. People, be kind. He was trying to warn people about a valid message he got.

    Calling him ignorent/other names is just rude

    Reviewing 1.5 (Aug 8, 2006)

    Victor. It would be interresting to know how you did come to the conclusion that this app contains/is a trojan? Sorry but just basing such assemption on your AV is a bit amateurish. Download Ghost security suite. Install it and execute the keyfinder. Ghostss will tell you exactly what the keyfinder does.

    Please provide me with your email adress and I will send you my IP and you can try to move my mouse around lol :D

    btw out of 15 AV´s just one reported it as "riskware" and another made a note of it as a "tool" but not virus and that is true in a sense since a procuct key (especially a corp one) is quite valuable as stated before.
    If anyone is not familiar with the term "false positive" I would suggest wikipedia, it will bring alot of light into your life and you can sleep better at night ;)

    Has come in handy a few times for reinstalls. To VictorAndrew, I've scanned with McAfee, Symantec and Kaspersky. Kaspersky points out that it could be used for nefarious purposes, but the app isn't malicious in itself.

    Reviewing 1.5 (Aug 7, 2006)

    Does what it says very well, performing an invaluable service for those that either can't find their ORIGINAL install discs or just want the security of an additional (hard)copy.

    VictorAnderson: Get a better AV program.

    romulus15: It is not a Trojan in any way - even by your definition.

    It is NOT ILLEGAL to discover/backup YOUR OWN product keys, even in a corporate situation. However, it is illegal to use it if YOU are not authorised to do so on the equipment.

    Once again, the responsibility is on the user NOT the tool.

  30. 5 out of 5 stars

    Reviewing 1.5 (Aug 7, 2006)

    Just want everyone to know that this does _NOT_ contain a malicious trojan.

    Some AV Firewalls and AV/security applications will flag it as a Trojan, especially at the corporate level.

    By definition: A trojan is "A program that appears legitimate, but performs some illicit activity when it is run."

    By definition the program in itself is a trojan. It is a peice of software that appears legitimate, and performs an illicit function (getting product keys).

    In a corporate environment, this would be a security risk, as it would be able to get the product code of a corporate site license, which could then be installed on home PCs which would not require activation.

    Your software is detecting it correctly for the corporate world. The sysadmin on the network should be notified that such a program is being downloaded and take necessary actions to prevent the theft of product codes.

    The program however does have legitimate uses in backing up product keys and does _no_ harm to your PC or attempt in any way to steal data.

    Please don't make such alarmist post unless you can back up and verify that the application is a trojan.

    This is an excellent application that our company has used for years to back up product codes of legitimate licenses for our clients when we reload their PCs.

    It's unfortunate that computer illiterate people like VictorAndrew are allowed to "review" programs on here.

    The ZIP on betanews is a complete archive. The author's web site does NOT contain a trojan, you're just using a lousy antivirus program, or you're just a moron. Both is probably true.

    This is an excellent program that does exactly as advertised. I've never had a computer it wouldn't pull the key on.

    Produkey by Nirsoft is also an excellent alternative with different features (such as export to HTML).

    4WD --- YES, its IS a trogan. If you're so conviced that Downloader.Delf-268 (Trojan) is not a trojan, go ahead download/run it and send me yer IP address and give me permission in email saying I can log into yer system and I'll prove it by moving yer mouse around and such... we just tested it here on a coupla junker machines we can re-ghost. Furntermore, AV program indicated antivirus - a virus is not a trojan.
    Geeze I don't understand why people are so determined to squeek and say this is a clean file when I've said its not and even named the trojan - what I gotta do log into yer machine or something? DAMN.

    Ok to the other guy claiming there is no trogan...I have backed up what I said by naming the offending trogan!!

    Name: Downloader.Delf-268 (Trojan)

    Damn what's wrong with you guys?

    urbanriot -- you are WRONG - the file does contain a trgan. I'm not using some pease of junk software here to find it - I've got an enterpise network here with 100's of machines any my sonicwall is catching it.

    THIS HAS TROGAN. - who are you urbanriot?? the author or something?

    And now the betanews download points directly to the authors download area, so yeah now its no longer incomplete, just infected.

    Hey I want something like this that works too - but IT HAS TROGAN.

    ...and ooh almost forgot - note that I'm saying WHICH TROGAN it has!

    1. Download on betanews is no good, incomplete archive.
    2. If you try to download this from the authors website.. IT CONTAINS A TROGAN!

    Name: Downloader.Delf-268 (Trojan)

    I have some words to say to the author regarding his ethics, but since such language here is prohibited I shall refrain.

    Yep, works exactly as described. Although I haven't tried the Change Key option (eh, like most people I only have one key). But it's a bit weird in that it's a self-extracting archive containing 4 seperate files rather than a self-contained executable. No, I'm not talking about an installer. It does what it sets out to do anyway, and that's what counts.

    Not bad, found my Windows version and CDkey, but it told me I have Microsoft Office 97 with CD-key "0001-000000" which is quite wrong, I have Office 2000 with an actual key.

    Really like this program though, if they could fix that it'd be great. Haven't tried the Change Windows Key yet, not planning to anytime soon :p
