Windows 7 ISO Verifier, for your downloading pleasure


Just between you and me, I’ve heard that one could obtain copies of Windows 7, including builds newer than the public betas, from some not-so-sanctioned sources. Of course I would know very little about how this works, but I understand that there is a process of verifying the integrity of files to ensure files are as described and have not been tampered with, however not everyone does this.

Leading up to the inevitable leak of the Windows 7 RTM build like a bottle of champagne shaken once too many times, I wanted to make this process of verifying file hashes even simpler by making it easy and convenient to generate and compare the hashes. With the help of Sven Groot, we came up with this little applet for your Windows 7 ISO verifying pleasure.

It couldn’t be any easier to use. Simple drag and drop an .ISO file onto this EXE, or double click on it and navigate to the file, then sit back and relax whilst it crunches the numbers. Once it generates a hash, it’ll compare it with a list of known and trustworthy hashes of ISOs to tell you exactly which build version and architecture it is known to be. This list will be updated live over the web so you won’t have to redownload the app.

Disclaimer: Like most entrepreneurs, I take no responsibility for the consequence of using this application. The information is provided only as a guide and cannot be used as evidence in an internet argument.

Update: As a few users have noted, this only works for English versions of Windows 7 ISOs so far.

Update 2: Added support for official retail US English RTM ISOs.

Update 3: With the wider public release of Windows 7, this tool is no longer kept up to date with the many and numerous versions of Windows 7 SKUs and languages. It is recommended you take personal care when using any ISOs.

  1. @Manmohanjit: I didn’t think of Server 2008 R2, but I just added 2 hashes for Server 2008 R2 RC, not really the target audience though.

  2. @Kevin CHEN: It only supports ISO files since I don’t think VHDs are practical for most people. If you’re downloading VHDs and converting them, hashing would be the least of your concerns I think 🙂

  3. MD5 may not be a great choice of algorithm these days:

    It might be more difficult to “fake” an MD5 hash with files as big as an iso (rainbow tables will certainly be useless for data that big but I don’t know how the common prefix stuff works exactly), and it seems unlikely anyone would bother to fake the MD5 when most people won’t check the hash at all, but if it’s just as easy to use a better algorithm then you might as well.

  4. @Leo Davidson: Yeah very valid point, however I think for file hashing, MD5 is a pretty good compromise between ubiquity and uniqueness.

  5. Why not just call it ‘Windows ISO Identifier’ to make it more or less future-proof (Windows 8, Windows Server, etc). Couple it with a simple database and let it roll. And as already suggested, a some sort of page would be nifty as well, just to browse the hashes (some might find it useful I guess).

  6. Good idea because some “scene” sites will try to put malware in some “releases”. Hope you’ll keep it updated for Windows 7 with SP1/..SPx ISO.

  7. @Andre – I completely agree! I would certainly use such utility quite regularly. I often find that I can’t recognize what image “this” is and it becomes quite a hassle. It would be so easy to do as well. If you were to pursue doing this, I would be more than willing to help with the database.

  8. If it’s just a matter of adding hashes, you may as well support other windows disc. At least XP and Vista since they are still used.

  9. An MD5 will be good enough for the time being, because if someone is willing to fake one on a file that size, you have bigger problems with the file you have leaked.

  10. Full sh….
    What for is it ?
    It’s not for russian 🙂 🙂
    Our iso’s it still not recognize, while they greatly work.

  11. Who tell me this verifier is legit after all ? Why not just check the hashes with programs like Hashtab and compare them with the OFFICIAL ones on MSDN/Technet ?

    1. you are absolutely right dear stranger friend…I have two Windows 7 .ISO (one from torrent and one from Microsoft) both are unrecognized on this ISO verifier…LOL

  12. @Yert: What bigger problems would you have with the file if a stronger hash meant you avoided using it at all?

    (I’m not saying there’s a definite/serious threat of anyone bothering to fake the MD5 hash of a leaked Windows ISO; just wondering what you meant.)

    @Alex: I guess it’s for leaked intermediate builds which aren’t on MSDN/Technet, and to make the check a bit easier as a bonus. (So maybe this tool will be more useful for Windows 8 since Windows 7 is about to RTM.)

    Presumably the idea is that a hash of those builds is provided by some trusted person, or at least someone you’d trust more than a file on a random download site.

    (Personally, I’d still avoid installing leaked builds on anything but a test VM, but maybe I’m more paranoid than other people. Well, that and who knows what is broken or experimental in a leaked build that didn’t go through any “public release” QA. Same as I’d never run a “nightly” web-browser build, really.)

  13. Just an FYI, I use a handy app called HashTab which adds a tab to the properties dialog in windows explorer, which does all the hash checks including MD5. It does not have a handy built in list of Win7 iso crc’s though.

  14. Why use proprietary software when you can just distribute a .sfv file (or a .md5 file or .sha1 file) with a list of the file names and their hashes, and then people can use their favorite hash verification utility to verify them? HashCheck is free, open-source, lightweight (smaller than this ISO Verifier), and it can verify using .sfv, .md5, or .sha1. And there’s QuickSFV, which can do .sfv and .md5. And if the user is using Linux to download, he can use sha1sum -c and or md5sum -c. It’s all about following simple, established standards since the .sfv, md5, and .sha1 formats are human readable and have been around for ages and are supported by a bunch of different apps. So just make a .md5 file with all of the hashes, distribute that, and let people download that list and use whatever their favorite utility is!

  15. I’m just trying this applet out I’ve had problems with the installation of Win 7, where there is just a black screen during the process of completion andhe build number is in the bottom right hand corner. I downloaded it from my Microsoft, any ideas?????

  16. just ran the verifier appears to be no problems with ISO images, I’ve tried both 32 and 64 bit any advice will be appreciated

  17. Holy crap DataMan47, chill out! This is a tool for the masses, not for those that feel there is only one right way to do something… you are free to go ahead and do as you suggested and provide info that to others yourself on your website. This is their offering and they’ll do it their way; not have you dictate to them how it should be done, lol!

  18. Hmmm… my RTM download of 7600.16384.090710-1945_x64fre_client_en-us_Retail_Ultimate-GRMCULXFRER_EN_DVD has failed.

  19. 1UK3:

    Try and download the verifier again. It seems like they have updated the program. Mine failed yesterday but today it tells me that i have a VALID image 🙂

    Still have no clue as to what to believe in terms of this really being RTM 🙁

  20. @Snowi

    Thanks for the heads up – all working now but as you say, can’t be sure that the build will be the actual RTM that is released in the future. I believe that Vista had about 4 different builds starting with 6000. before being released officially – I could be wrong about that though.

  21. To vader1 and anyone eles who experiences the black screen at completion of installation: turn on your second monitor 🙂

    I would love it if the 7600 is in fact the RTM but I’m gonna wait to install until I’m sure. The RC still works great.

  22. hi this is not working. im going to say that i downloaded windows 7 RC from Microsoft website and tried to verified using ISO verifier. but it shows that its a invalid ISO. i cant believe. i directly download from microsoft site. shall i know which is fake. ISO verifier or downloading microsoft website.

  23. 7600.16385.090713-1255_x86fre_client_en-us_Retail_Ultimate-GRMCULFRER_EN_DVD.iso is also not recognized and i’ve got it from trusted source.

  24. James Cage, you may have received this from a trusted source. But that trusted source might have been smart enough not to give away the true iso as MS might be able to track the owner. I do not doubt the contents of what you got are legit, but they may have been repackaged into an iso.

  25. Does this support the RTM?
    Build 7600.16385.090713-1255

    How would we go about finding what versions you have in the database?

    BTW, awesome program.

  26. I’ve recently checked my ISO Build 7600.16385.090713-1255 x64 and it was all OK. I’m so glad !!!

  27. I can also verify that the x86 English Win7 RTM ISO is not correctly identified. I have hashed it against the RTM hashes and it verifies CRC32, MD5, and SHA1, but the tool does not recognize it as a valid ISO.

  28. Very nice, thank you. I’m fairly certain my ISOs are legit, but I’m glad there’s a tool for everyone to use. Nice work, btw.

  29. Windows (E) version x64 shows as not verified also.


    It passes CRC32, MD5, and SHA1 in Hashtab.

  30. Not being funny, but who are you that anyone should trust this process…??

    Unless I have seen the actual checksums on the microsoft site, they could be anything!!!! There seems tobe loads of variations of checksums kicking about, and ive nto seen any on a 100% trustowrthy source….

  31. not detecting OEM win 7, but of course cannot guarantee these are genuine unless seen on a micro$ost site

  32. Perhaps you could also include MD5 identification of the proper ‘adjustment’ program to use with each version. Or simply just allow for the proper and verified identification of each crk. What is the MD5 of YOUR program so that we know your work will not be modified by someone working for an evil corporation?

  33. Seems to work for ‘Ultimate,’ but I’m getting negative results with other editions (Pro, Home Premium, etc.)

  34. Hi guys, any download links for 7600.16385.090713-1255_x64fre_client_en-us_OEM_Ultimate-GRMCULXFREO_EN _DVD.iso? Thanks

  35. @Long Zheng
    how do you know the hashes you have are good ? did you get them from microsoft or calculate from ISOs by yourself ?

  36. Microsoft’s download manager applet for the RC had an MD5 checksum built into it, according to a source… it didn’t either display it or notify you if it was valid, it simply would fail a bad download from microsoft if it didnt match. I doubt that many people received a bad download from µSoft but it is possible. the source then said what the MD5 was.. later I read somewhere else what the MD5 checksum was supposed to be for the ISO..

    yes, you get them ( the MD5, and also the ISO) from a source, whether that source is directly from µSoft or someone else. Then you calculate, generate, or produce in some manner the MD5 of the file you have on your computer using any MD5 calculator. I’ll post a link to my favorite one here.. it can calc two at once, and if you wish you can paste the Published MD5 in the textbox and once you browse and select the ISO file it tells you if it matches. If you do NOT paste an MD5 into the textbox and then browse and select the ISO file, it simply tells you what the MD5 is of the file…. NOTE: this can do TWO MD5 files at once. I dont recommend doing this because it will not be any faster, in fact it will be slower if the two files are on the same physical hard drive, due to the head seeking behaviour..
    oops is under reconstruction as of mid sept 2009.

    try this instead, until mark’s site is reconstructed, his program is better I think. He also has other useful apps.
    A Very talented person.
    not that this other program wasnt made by someone talented, i just dont know them as well.

  37. When it is all said and done, you have no way of knowing whether something is genuine or not, until you read it from the horses mouth… many supposed RTM iso’s are chimeric like WZOR’s which has parts of it from an earlier release and the rest from the new.

    If you want the real thing and cannot trust when a large group of people are saying it is, and then using a program like this to verify what they are all saying, It’s time for you to stop bothering us with your fussing, and simply wait for it to be on sale in a store like the rest of the masses. If you feel like going on an adventure sooner than your neighbors, please continue reading.

    (pasted below)

    On July 22 Microsoft released Windows 7 to manufacturing and started shipping images of the operating system to original equipment manufacturers. Next in line to get the gold bits of Windows 7 will be ISVs (Independent software vendors) and IHVs (Independent hardware vendors) as well as MSDN and TechNet subscribers on August 6th. At the same time, it is highly probable that Windows 7 RTM will be leaked and made available in the wild. In the meantime, Daniel Melanchthon, technical evangelist for Security and Messaging in the Developer & Platform Strategy Group at Microsoft Germany, made public the official SHA-1 and MD5 Checksum Hash information for what appear to be the original MSDN/TechNet DVD ISO Images of Windows 7 RTM Build 7600.16385.

    The information published by Melanchthon will allow users to compare the MD5 and SHA-1 hash checksum values of any Windows 7 ISO images with the official SHA1, MD5 and CRC hash checksum values. If the values coincide then users have a guarantee that the downloads they checked are in fact the original ISO images of Windows 7 provided by Microsoft and that the files have not been tampered with in any way.

    In this regard, Microsoft is offering the File Checksum Integrity Verifier utility. “The File Checksum Integrity Verifier (FCIV) is a command-prompt utility that computes and verifies cryptographic hash values of files. FCIV can compute MD5 or SHA-1 cryptographic hash values. These values can be displayed on the screen or saved in an XML file database for later use and verification,” the company informed.

    I have included below the Windows 7 RTM Build 7600.16385 DVD ISO SHA-1 information provided by Melanchthon, along with additional MD5 Checksum Hash values I came across in the wild.

    the D0B8… etc etc (32 bit)
    and the F43D… etc etc (64 bit)
    are valid in my opinion as well as some guy who works at µSoft, and the writer of this applet. and most of the people who are running W7..

    but you never know, they might change something at the last minute. No one has mentioned any trojans or viruses in these ISO’s. (because there aren’t any)


    Save the planet, burn ONE dvd of this, instead of a 32 and a 64, this is BOTH. only 3.47 GB (3,735,056,384 bytes) note the download torrent is slightly larger due to to small text files. the md5 stated is for the ISO itself.

    Windows_7_Ultimate_Activated_AIO (32 AND 64 bit versions, you pick when installing)
    MD5: 60e5a382e6dc932165b1aaa60b991c98

    from a search on piratebay it’s Windows_7_Ultimate_AIO_Activated
    (spaces inserted for legibility, and to protect n00bs from themselves)


  38. It is NOT a hacked copy, it is the OTHER still valid but lesser known RTM ISO’s that were available almost exactly at the same time. WZOR received the win 7 RTM WIM or VHD file, which is a sort of zip or cabinet file containing the files to install. His WIM or VHD file is exactly the same as any other RTM wim, with the exception of an AIO file ( all in one, where they stick 32 and 64 bit files in the same iso so the installer gets to choose which one).

    The confusing part is WHY isnt his ISO the same as the full RTM? well, it installs the same file, although he used the rest of the files ( everything but the Wim or Vhd, essentially), from a previous version. These files are essentially just the boot and the installer and are not going to be part of the installed version of windows. It was a clever way to use the RTM VHD package he got and made an ISO which installed the real RTM on your computer. The package on both Wzor and the other RTM are the same.

    The makers of this ISO verifying program knew about this when they included the MD5 checksum for these ISO’s when they made it. It IS a valid RTM, and although neither is a very useful AIO version, it is a valid one.

    if you MUST be paranoid, I recommend buying Win7, and paying full retail price


    You can do an installation of both the technet or other RTM and also Wzor into separate partitions,
    and then without running them further, ( so you wont make various and sundry temporary files and web cookies and such), do a file comparison with CDCheck, which is a fast folder or drive comparing program (ignores dates and attributes, only compares file Data) Please also dont try to activate anything before you do the check, and keep them both disconnected from the internet, too, until you decide to use them. Doing so would make one different from the other, possibly, due to random keys or such, based on the activator.

    IF any file is different, please let us know, I’ll eat one of my socks for each file different and post it on channel 4 news. or 4 channel b, whichever is more convenient.

    WZOR’s RTM release happened to be one Ive used for a while, and only have abandoned ANY thing truly checkable by this iso verifyer because I am involved in using AIO’s.

    AIO versions are superior, based on the ability to install either version of Win7, the 32 or 64 bit on installation. Also there is the possibility of installing a version such as starter, on a slower computer with slightly below the minimal resources available, so you can essentially have a single DVD ( two layer with tools added) to install any Windows 7 version you need to on any computer capable of running Some version of it. The Language packs are all available from Windows Update and other than from paranoia or convenience are people making or downloading ISO’s or custom ISO’s to include an other language.

    We are now in the state where we have to decide between having a KNOWN common AIO ISO with english as standard and add language packs later which will let us all KNOW for certain that we have the real deal,


    Everyone and their babelfish trying to make ISO’s from updates, combining them so your cousin and his blonde wife can have a dvd of win7 with JUST Farsi And Norwegian (Bokmal AND Nyorsk) preinstalled languages …which will fuck up everyone’s attempts at getting something for nothing by making SO many different ISO versions available that people will give up.

    It is Quite possible that Microsoft itself is contributing to this mess and everyone and their dog are getting help from them and making custom installation DVD’s using Microsoft’s OWN WAIK.
    Windows Automated Installation KIT is a tool that Microsoft has graciously made a version compatible with Windows 7. It is typically used by network or systems administrators to make modified versions of Windows to install, including the options to install over networks, and options to ADD to or REMOVE from windows itself. Scripted automatic installation, with NO user options, or select options, with the keys to the software included and also modifying settings of the computer.

    I recommend you do NOT try to do this, unless you have had experience doing this on previous versions of windows, we do NOT need to see your messy ISO here causing troubles for people.

    WZOR is not some lame person who is trying to ruin your day.
    The Win7 RTM by WZOR is vaild.
    End of story.

    use this:
    Windows_7_Ultimate_Activated_AIO (its 32 AND 64 bit versions, you pick when installing)
    MD5: 60e5a382e6dc932165b1aaa60b991c98

    that way you wont have problems with picking the latest activator.

  39. @ “ed from brighton”
    So is this (MD5: 60e5a382e6dc932165b1aaa60b991c98) the best RTM to download??? Please reply.

  40. im confused
    7600.16385.090713-1255_x86fre_client_en-us_Retail_Ultimate-GRMCULFRER_ EN_DVD.iso

    what goes infront of this link?

  41. Hi,

    Just downloaded W7 Enterprise directly from Microsoft and your tool says that it is not a recognized one …



    Regards, Oscar.

  42. Terribly sorry to have been away for so long.

    Yes, Jack.
    This (MD5: 60e5a382e6dc932165b1aaa60b991c98) is the best to download.
    It is unfortunately not recognized, although WZOR’s early pre-RTM RTM is.
    WZOR is the nice person who did the very earliest RTM, making it from the
    large new cabinet file and the earlier RC dvd install/boot file. The end result
    of WZOR’s DVD and the RTM is the same, the exact same win 7 is installed
    onto your computer. WZOR did not have the RTM available, only the install
    WIM, which was good enough to make a RTM DVD available when there wasn’t
    one yet… So, RTM and WZOR rtm are both? recognized here, with this program
    I believe… it has been so long since I have even bothered with this program that I
    have forgotten whether Wzor and RTM are both verified here.

    I believe this is the operating system of the future, with the exception of a few things.
    It is because they have not made changes to include any AIO.
    An all in one (AIO) has the advantage of owning a single DVD that is capable of
    installing Windows 7 onto a 32 or 64 bit machine.

    I personally like the options of having multiple languages, and not having to download them.
    However, since this AIO passes windows checks and does all updates and service packs, etc,
    with the optional languages also being able to be installed as updates, I simply use this AIO.

    It is of course, used to do a NEW,clean or recovery/repair install of Win7.

    I feel, that is someone feels the need to do an UPgrade install of Windows 7 for fear of
    losing some programs, or settings from Vista, that these same people do not now how to
    back up their files, or create and use a separate partition for data enough to feel safe doing so.
    Such persons should make CD/DVD/or network copies of anything they want to keep, and
    do a clean install. No one is seriously keeping anything important in the same partition as
    their operating system are they? Really?! I must insist that you learn to use some sort of
    CD/DVD recording program, either the included XP,Vista file saving to CD/DVD or even better,
    to use IMGBurn ( a totally free, excellent program that is Indeed capable of saving files and folders
    to CD/DVD.)

    DO please read on, it gets better.

    The problem with RTM (either the broad release from Technet, or WZOR’s clever
    ISO is that such DVD’s need to be activated, registered, etc etc etc.
    Either thru normal microsoft methods, or with a ‘helper’ application.

    THIS iso (MD5: 60e5a382e6dc932165b1aaa60b991c98), that you asked about
    is in fact a combination of the 32 bit RTM and the 64 bit RTM’s WIM files
    both being the full set of files needed to install win 7. ALL a WIM file is
    is microsoft’s way of saying, “We are making a new type of ZIP or RAR
    file, and we don’t want you monkeys touching it. We will now use it as our
    way of packaging all the files needed to install our operating systems.”

    So dear friend orbit30 carefully combined said WIM files together, leaving
    nothing out, and made it work with the install/setup files of the DVD.
    He also made adjustments as to only modifying the few windows 7 files
    and registry settings that involve activation.

    After installing this AIO, you will be ALREADY Activated, indeed, there will
    be available updates both critical and optional and this is normal.
    It means your windows is working like it should. Unfortunately for persons
    whose english is not fluent, this is only available in English. Not to worry!
    This AIO can download (like all the other Ultimate win 7’s) the language
    of your choice. A fun thing to do when you have a few minutes on your hands
    is practice setting the language to another, and then back to english,
    or among any two languages with which you can manage doing such a thing.
    You then switch it to something you are NOT familiar with, or your audience,
    and then carry on in arabic or russian or greek as if nothing were out of the
    ordinary for you…. 🙂 you can see this is also an option for particular logins.
    Yes you can make each particular windows account login use a different
    language and this makes for fun at work on days when your coworker is
    not being productive anyway as if it were a bank holiday and he needs a bit
    of prodding. If Mister Lazybones takes a long time to get your help with his
    screenful of hebrew or arab script, together with the backwards menus and
    start menu, you will know he has been slacking, indeed!

    A search of Google for both 60e5a382e6dc932165b1aaa60b991c98 and TORRENT currently gives me 478 possible webpages to find this on.

    Bing gives me only 6 such pages, however the second Bing listing is this thread we are attending to now –
    which leaves us five possible download locations. Bing has some results filtered, which you can understand why, but the very first link is to the piratebay. Someone should log in and post a TEXT version of the torrent file contents so that you may see what it says about the checksum.

  43. No this program does not have the full matrix of all possible options.
    Please use a regular MD5 checksum programme on your ISO files if you have one this program does not verify.

    With 5 possible basic versions: Starter, Home Premium, Professional, Enterprise, Ultimate.

    The 5 possible basic versions were also supposed to include for the EU a version lacking both InternetExplorer and WindowsMediaPlayer. These EU-only versions were supposed to be Win7-N or something to that effect. I haven’t seen any here in Brighton, save for wanks catalogueing the entire universe of files in case zaphod beeblebrox comes by with some ‘earth moving equipment and a shovel.

    so Essentially 5 Basic Colours of Windows 7.
    Shade those with but ONE of the few 34 languages Redmond has deemed being worthy and you get
    a multiverse of 170 versions of Windows7. Go ahead a little further and include the EU-only versions and you are up to 340 versions… Drop the EU-only versions, and Colour the 5 civilised tribes with all the combinametrics of any two unique languages of the set of 34 and you have enough DVD’s to ruin a perfectly good DVD player’s day.

    If you have trouble with English, learn how to set up hands-free boot configuration files so that your EnglishWindows7Ultimate will also install your preferred language. There is a Microsoft preinstall configuration environment that allows all sorts of customisations and options from the very basic type of options such as not having to type or click anything, to including drivers, to setting security levels and also pre installing 3rd party software.

  44. Hellohello Long,

    I used your verifier and it says my copy of ISO is not a valid. However, it is a “pre-activated” copy of windows that doesn’t need serial numbers, etc? Does this mean it can not be verified?

    -Is there any way to ensure that my ISO doesn’t have malware/spyware in it? Of example, since I’ve installed it, maybe running ‘spybot search and destry’ would be able to find out if there is malicious software on my computer?

    many thanks.

  45. Hi vmky, i think there will be no way to check it bro..

    even you can scan all the entire disc and found no spyware there, you still can not ensure that the disc is not modified (original), because it is modified.
    ISO verifier just check the MD5 of the ISO, and then compare it from microsoft original ISO.
    and as long as i know, the md5 will changed if the file is modified, and will never be the same again.

  46. thanks boni… appreciate your help.

    i see your point – however, how can i be sure that my current OS installation is safe? i’ve installed various spyware tracking and antivirus tools – i am hoping if it was dodgy, it would’ve been found.

  47. I think if you have no problem so far then there is nothing to worry.

    But if you are not sure about it, you can re download the original ISO from official download links, i have the link list on my blog, just check it if you are interesting, all the links there is from the official microsoft.

    But if you buy it from microsoft, or original OEM from notebook you bought, there is nothing to worry.

    Hope this can help you bro…

  48. NOTE: this program is only capable of testing iso’s of the RTM and some beta versions.
    it is a great program if you wish to test an RTM or a Beta ISO.

    If you wish to download a singularly very good single ISO that allows Either 32 or 64 bit installation,

    I can recommend one which is Neither a beta, nor a Legal copy of the RTM versions which Requires validation from µSoft (otherwise know as ‘Microsoft’).

    The ISO I am speaking of was popularized as being MADE from the Ultimate 32 and Ultimate 64 bit RTM’s with one addendum, the WGA-like validation-requirement has been bypassed. Not any one of the other files packed into the largest file on the DVD’s have been changed, save to allow the installer a choice either 32 or 64 bits. There was a menu to select which of the lesser versions of Windows 7 ranging from the version you purchased on down to the lowest version, but all based on being the same 32 or 64 bits that the DVD is capable of. The AIO (all-in-one) version co-opted that menu choice of versions to only allow a bit size choice of 32 or 64 instead of an Ultimate Win7 installation.

    WZOR’s leaked rtm version had the large-packed-file windows RTM file slipstreamed into a beta install, which gave people an RTM installation based on it using Lenovo(ibm) bios installed keys. This resulted in an RTM installation that win7 believed was a valid install on a new computer that had BOTH(or combined) Vista and Win7 keys on it to allow for new computer purchasers to get their free upgrade to win7.

    Orbit30 took away the need for any After-installation modification and caused win7 to ‘forget’ the need to be authenticated by microsoft.

    KB97133 is a patch from microsoft which replaces the missing requirements and thus FIXES pirated windows 7 so that you have to pay for it, or be harassed until you do. Simply choose to ignore downloading or installing or being reminded again of this upgrade by selecting “hide” this upgrade and it will never be an issue.

    This program is rather outdated for use by smart people/poor people/or people who wish NOT to give away money.
    This program is perfectly wonderful for those people who want to download a legal version of windows.
    If you pay for a download of a legal version of windows, and then distrust Microsoft from being competent enough to be able to accurately send a self-verifying download (with md5) to you and thus want to verify it with a third party application from some guy on the internet instead of verifying the iso yourself with an md5 program against Microsoft’s published md5’s –

    Then why not simply download a non-legal version of windows? this program doesn’t verify it? pshaw!

    You are here because you do not trust either Microsoft’s downloader or your own competence to find/install/and use an MD’5 generator and then use your own eyes? You should be shot and put out of all our miseries.

    Not trusting Microsoft but Trusting this guy? Why not simply trust a hacked iso? There is a guy named Mark Russinovich who used to work for a company (sysinternals aka system internals) that Microsoft has bought and is using their technology and Mark himself to do their detail work. They have a program called, Root Kit Revealer, among other many many fine utilities. I find NOT one single flaw in the AIO ISO.

    If you do not trust the two people who brought free Windows 7 computing to the world, ie THE penultimate people to disable Windows7 activation technologies, you should ‘an hero’ yourself, and begone from this website and the internet in general. Don’t bother us with any more questions. Go pay for it. bill gates will thank you and give your money to people in some poor country anyway. He does not need more money. In fact he is devoting the rest of his life to giving it away. Why not HELP him do this and use a pirated version of windows and save Microsoft even more money by them not having to do much in the way of accounting for sales of windows 7 in your area? Keep the money and use it locally to help someone in need.

    To Orbit30 and WZOR: I have achieved so much only because I have stood on the backs of Giants, thank you.

    Windows7(AIO) 32 and 64bit Ultimate Version
    MD5: 60e5a382e6dc932165b1aaa60b991c98

    Of all my classmates, not one of my classmates who use windows of ANY kind,
    whose computers did not already come with windows 7, are using legal versions, not one.

    not 3.1 ( for giggles and when putting it on someone’s laptop when they’ve had a bit too much to drink and have passed out giving us ample time to demote their laptop to wired-networking-only mode. This method requires win3.1 installation, followed by the Win32s 32 bit extension package, followed by TrumpetWinsock which gives windows a nice tcp/ip stack and then followed by Netscape Navigator so they can browse the interwebz and TRY to use webcrawler) (Even funnier is pointing their browser home page to the InternetWaybackMachine on some outdated news as being current news. It all depends on the date and seasonal current events. O.J. Simpson leading police on a highway chase, etc. etc.)

    not Windows95/98/98SE: what ever for? to host the Windows REAL-GOOD-NOW (winRGN) java applet for the same reasons as above.

    not even WindowsXP. For when schmucks have non-fully-compliant ACPI BIOSes and havent upgraded to something workable. We were using gold corporate (SP0) cd’s with rollups to SP1,SP2, and SP3. You have to use registry/&other mods on XP to allow for software raid, and to allow for 50+ tcp/ip connections. What a bother.

    None of us have paid for Windows, ever, save for jacked-up prices on the few computers we have bought already built, which is mostly laptops truth-be-told. Why should you? Peace of mind? buggers! you can’t help stupid people.

  49. Hi there,

    very bad to see that you no longer update this tool 🙁

    I want to verify my german Windows 7 Ultimate x64 ISO download.. ! -.-



  50. This is almost a silly thread, but who am I to say. Just an opinion not worth much probably, but geez all of this is kind of silly.

  51. I have 7601.17514.101119-1850_x64fre_client_en-us_Retail_Ultimate-GRMCULXFRER_EN_DVD.iso
    MD5(128bit): 56A26636EC667799F5A7F42F142C772D
    SHA1(160bit): 1693B6CB50B90D96FC3C04E4329604FEBA88CD51

    Can anyone confirm that it is ok?
