Windows Product Activation Creator Reveals Truth Behind XP's Most Notorious Product Key (tomshardware.com) 34

Dave W. Plummer, the Microsoft developer who created Task Manager and helped build Windows Product Activation, has revealed the origins of Windows XP's most notorious product key. The alphanumeric string FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8 was not cracked through clever hacking but leaked as a legitimate volume licensing key five weeks before XP's October 2001 release.

A warez group distributed the key alongside special corporate installation media. Windows Product Activation generated hardware IDs from system components and sent them to Microsoft for validation. The leaked volume licensing key bypassed this entirely. The system recognized it as corporate licensing and skipped phone-home activation. Users could install XP without activation prompts or 30-day timers. Microsoft later blacklisted the key.

  • ... that as Microsoft cracks down on local-only [slashdot.org] activation, a healthy market will develop for these 'special' keys.

      Microsoft VL keys don't work like that anymore.

        The important part is the 'skip phone-home'. Without a special product code and/or key for this, how would one ever configure a new machine in a SCIF? If it phoned home, the Department of War would drop by Redmond HQ pretty damned fast.

    I remember the keys for Windows 95, along with related Microsoft products, being laughably easily defeated by the number 7. It didn't matter what the first 3 or 4 numbers were as long as the last 7 numbers, when added together, were evenly divisible by 7. That's why 123-1234567 and 1234-1111111 would work.

  • It's quite easy to activate XP now all these years later. So if you have some old, isolated machine that requires XP, you can install it still.

      I still run an old XP in a VM with only a bittorrent client in it, nothing else. It runs in a headless Linux host. I remember I originally did it as a test to see how long it would take before it would be hacked. It's been running for 20 years !

    The older I get and the longer I work in IT, the more I believe that software activation is to be avoided at all costs, especially time-limited software activation.

    I've got a Framework laptop on pre-order because I'm pretty certain I really don't want Windows. I have only one Windows machine at home, on Windows 10, and I'm really not convinced that it offers me anything at all that I want. Much of my early use of that device was getting AROUND shite that I don't want, and fudging things to make them work. Windows 11 needs that x 100, from my experiences with it.

    And now they have the 10 ESU stuff, which is just unnecessary, especially after they promised "no more new versions of Windows".

    So I think I'm done. Again. Having previously used Slackware as my primary desktop for 10 years.

    I audited the software on my primary machine and I don't think there's a single thing on there's that proprietary, needs "activation" (I "activated" my software when I clicked the download button, giving it executable permissions or via the use of credit card to purchase it in the first place, thanks) or that can't work on Linux.

    I'm at that point again where I need to computer do work for me, not run off and do whatever the hell it likes. Between activation, AI, mandatory cloud accounts, "search everything" rather than just organise stuff, etc. I think I'm done again.

    I have 20 years until retirement. I reckon that's a viable proposition to reach there without having to have a single Windows machine at home again.

      You don't have to buy a laptop from Framework just to not have one with Windows on. Dell, HP, Lenovo will all sell you laptops without Windows on, Dell for example list Ubuntu as a pre-installed OS option on some of their range, and if you buy one with Windows on there's nothing at all stopping you from just wiping the drive and putting Linux on.

        And, for decades, they didn't. And they still don't really. You have to fight like hell to find the models, you have to pay overpriced prices to get to it, you have to basically forget technical support for it (I've had them say "can you just boot Windows so we can check that's working", etc.), they don't provide proper drivers, and ongoing support is dubious.

        And so if I'm going to have to drop that much on those models which do support that option, and deal with that? I'm just going to buy a product des
