Windows XP Activation Algorithm Has Been Cracked (theregister.com) 59

Posted by msmash from the how-about-that dept.
Liam Proven, reporting for The Register: Over 21 years after it first came out, the Microsoft operating system that will not die is receiving another lease of life. It's possible to activate new installations, safely and securely, without a crack, off line. A blog post on tinyapps has revealed the hot news that nobody sane has been waiting for: the algorithm that Microsoft uses to validate Windows XP product keys has been cracked and reimplemented. As a result it's now possible to generate valid activation codes for Windows XP, without an internet connection, even though Microsoft has turned off all the activation servers.

This is not a recommendation But first, a word of caution and restraint. Please don't take this article as a recommendation to run Windows XP. It wasn't the most secure of operating systems back in 2001, and you really should not be running it in 2023 -- especially not on anything that is connected to the internet. However, saying that, the problem is that sometimes people need to. There is, for example, hardware out there that only works with Windows XP and won't work with anything newer... and some of it might be very expensive hardware, which is still perfectly functional -- but which requires a long-obsolete version of Windows to operate it. If you are lumbered with such a device, or you have got some single specific and very particular piece of software that you need to run and which doesn't work properly on any newer version of Windows, then you may be forced to use XP. If so, one of the problems is that Microsoft has turned off the activation servers, so even if you install clean fresh copy, you can no longer activate it over the Internet. (Allegedly, the telephone activation service still works, if that's an option for you.)

      Web browsing in xp has been broken for a while now anyway. You might be able to get away with basic html, but any web app will trip compatibility. There are only two actively developed browsers left, one based on an old version of Pale Moon and one based on an old version of Firefox. I have given up browsing in xp even in virtual machines. If I need to transfer files to XP I download from a modern system. Even retro gaming on XP is limited due to the shutdown of online servers for games. The only real use for xp is embedded offline hardware with a multi decade lifespan.

    People were warning what would happen to XP once Microsoft wouldn't activate it anymore back in 2001. People are still able to use 40 year old dos applications thanks to the cracking scene that existed back then. We are already seeing drmed software and movies disappering when companies get greedy or just plain evil. Embedded systems with old XP hardware can at last be salvaged thanks to this crack.
    • I'm a little unclear on why this matters at all, XP was the last version of Windows which didn't require activation. Maybe it matters for some of the later discs or something, which possibly came with Genuine Advantage baked in, but for (I'm guessing) most installs that was something you could avoid. Provided that you were paying attention and didn't just install all updates.

      It's not a coincidence that XP is the last version of Windows that I used.

      • Windows XP was the first version of Windows that required activation. The last version of Windows that didn't require activation was Windows ME. Or I suppose Windows 2000, though ME was released after 2000.

        Not all PC's required that XP be activated by phoning home to Microsoft. Some OEMs would essentially bake the product key into the BIOS, and Windows could use that to activate itself automatically without ever phoning home.

        • Windows XP was released in 2001. Windows Genuine Advantage was released as an update in, I think, 2005 or 2006. If you just installed all updates blindly then you would be stuck with it, and couldn't remove it once it was on your system, but if you paid attention then you could just not install that update.

Pretty sure if a fresh XP install hits the open net its gonna be wildly vulrerable to attach immediately and MS can't be connected to that happening no matter how many disclaimers they put on it.

        It's perfectly possible for MS to release software for "educational purposes" expressly excluding all guarantees of performance and disclaiming all responsibility. The likely largest reason why they cannot do this with Windows XP is that a lot of Windows isn't Microsoft code, it is code licensed from other parties. In order to release XP as freeware, MS would need either a) to comb through it and build a distribution that excludes all third-party components (if that's even possible), or b) get agreement fro

        • For sure I am not saying it isn't possible, just so legally risky and dubious with so little upside that it's functionally not even a realistic possibility. The valid point you bring up only doubles down on that.

          Releasing XP again in any form whatsoever is pretty much 99.999% downside and risk and the only upside is to a very small and niche group of enthusiasts who already likely know how to access the software anyways.

  • There are still very large, expensive pieces of capital equipment with an EOL far longer than an OS, and many run XP. The issue now is not getting XP installed, its finding hardware that XP will install on in the first place. The last chipsets XP will recognize are now more than a decade obsolete, and maintaining that hardware has become more problematic than maintaining an OS on an air gapped system.

    A fresh installation of XP is a hassle to get boostrapped these days, as it doesn't come with anything you can use to download what you need.

    • Use the phone activation system to activate Windows 7, it works every time (it's just a PITA because it takes over 10 minutes). After the systems asks you for the string of numbers it will then ask you how many computers you have installed this copy of Windows 7 on. Always respond with "ZERO" and after a few seconds you'll hear "verified". The system will then read you a string of numbers to type in to activate Windows 7.

Although I do not even have an optical drive in my desktop any more, I keep a USB2 DVDRW around in case I want to rip a disc or something.

    I don't have any other MSWind software that I'm even interested, and MSWind98 broke the applications. (Well, not actually broke, just made them unusable due to timing errors.)

    OTOH, I've gotten along without those applications for a few decades now, so I probably wouldn't go through a lot of bother to get them to run anyway

        I've got a complete set, but not a computer that it will run on. The last time I tried it wouldn't accept a disk version of the boot floppy, but the system wouldn't boot from a floppy. (Well, that was a decade ago. I've still got the CD and the probably the floppy, but no system that can use them.)

        • I realize that's an issue, as nothing has a floppy anymore, but that's not a problem; the images I'm referring are already completely installed from the original media - no original discs (CD or floppies) are required at all. The image is a virtual hard disk image, usually a several GB large file or files that comprise a VMDK, which is a virtual disk image that's used by VirtualBox or VMWare Players.

          Those are two good free VM's out there that will boot up the OS image you downloaded directly from the hard

  • I know of some stand alone industrial control systems that still run XP. The software and hardware is XP only and unfortunately for those smaller companies they let themselves get so locked in that being forced to upgrade would bankrupt them. Now all they need to worry about is compatible hardware.

    As long as a XP system is isolated from the Internet and only runs a single dedicated application like a CAN bus connected license server for the NC machines there isn't much of a risk to using an old EOL'd OS.
