Has Microsoft Discontinued Offline Activation of Windows? (neowin.net) 99

An anonymous reader shared this report from Neowin: Offline Windows activation has been possible to do using the phone. However, it looks like Microsoft has quietly killed off that method as users online have found that they are no longer able to activate the OS using it... [As documented by Windows user Ben Kleinberg on his YouTube channel], Now when trying to activate the OS by attempting to call the phone number for Microsoft Product Activation, an automated voice response says the following: "Support for product activation has moved online. For the fastest and most convenient way to activate your product, please visit our online product activation portal at aka.ms/aoh"

If you are wondering, that link takes users to the Microsoft Product Activation Portal for online activation. Thus it appears that offline ways to activate Windows may no longer be available even though the official support documentation by the company may not reflect it yet.

      Indeed. But I still think MS needs to keep the no-account open, because the GDPR does not actually allow forced sign-up unless it is necessary for the nature of the service. MS is trying to give that appearance (via one-drive, for example), but it is not going to hold up in court.

      • Errr false. I don't know if you know what a sign-up is or how the GDPR works, but online activation is most definitely permitted as a requirement for purchasing a product, as does forced accounts to use a product. What the GDPR does provide is a requirement that you aren't forced into an online account / activation process after purchase that didn't exist at the time of the purchase. E.g. Meta requiring Oculus users suddenly migrate to a Facebook account or have their devices unusable was a GDPR violation.

    • Sounds great... I didn't want to use any of the software or games I bought.
      Better to run Windows in a VM just to run the new game or program, and take a performance hit.
      Now... if someone made a version of *Nix that could natively install Windows programs and whatnot _without using WINE or a VM_ (the way Windows handles it), that might push more people to *Nix, otherwise it's just a hobby thing.

      It should be relatively easy to reverse engineer the way that Windows installers are put together and processed so

    Sure seems that way, if the only way you can activate Windows is to have an active internet connection.

    Now I suspect DoD and other large scale accounts can cut a deal to get a "gold master" that doesn't contain a requirement for on-line activation. But it seems to me that there are good reasons to have air-gapped systems in manufacturing or similar process control situations, as one example domain. Previously, you could obtain and transfer updates through a physical device (which, of course, you'd have to verify and trust the device and its contents.)

    I guess Iran won't be using this version of Windows for uranium processing...

    • I don't think there's such thing as an air gapped windows 11 machine.
      • There are plenty of air gaped offline DOD Win 11 systems, just. not as simple to activate but you can still activate with offline active directory and other methods.

      I'm guessing you don't know all the ways to activate Windows then.

      Standard Windows keys require Microsoft for activation. MAK (multi-activation keys) also require MS. However, KMS (Key Management Service) however does not. KMS uses a locally controlled server for activation. This is quite common in large organizations that deal with a high quantity of machines (think fortune 500 orgs w/ 100k+ employees w/ laptops). This would of course also cover the military. Do you think the DoD was using phone activation this entire time for their air-gapped machines? No, they have the private DoD network w/ this type of infrastructure (at least, this is my assumption)

        I ran several smaller SCIFs for years at my last job.

        Yes. We had to do offline activations. Office too. Via phones that also needed temporary approval in SCIFs. Yes. Other larger shops might have been approved for a local KMS server inside a SCIF. Assuming you can actually maintain a KMS server permanently offline. Since part of SCIF mandates also require OS patching with read-only media, it can become a lot more complex to maintain.

      Literally no corporations DoD or small enterprises rely on Microsoft for activation. They use a Key management Service to activate locally provisioned windows systems without any need to reach the internet outside the organisation. This has been the case since the days of Windows Vista.

      Heck KMS is the default piracy workaround for windows in general. Pirated copies of Windows and Office are activated by running KMS locally on the machine.

    • Not at all they have kms and mak for that. If yiu are running an serious air gapped network you would have access and kmowledge of them.

      Hate to burst your bubble on that, but at my previous (defense contractor) shop, the best Microsoft could offer is LTSC variants to be used in our air-gapped (classified) rooms, which we had to activate offline via phone many times when hardware or license issues came up (Office offline activation is no picnic either). I don’t see how this latest action is going to fly in those environments. Wiping the drive and rebuilding from scratch online isn’t always an option, which now seems to be the o

      • For the updates, you could just run WSUS on a machine with an outside connection, and the inner office network would download updates from that one machine which has something like 'the Great Wall of China' as a firewall that prevents the office from touching the dirty outside world... or, let the Windows Updates through, but that's it, and filter all other traffic with firewalls. In an environment like that, the desk workers shouldn't be able to download anything any, and the websites they can access shou

    Activation will be tied to your Microsoft Account, and a subscription will also be assigned to it.

      I see where you are going, Adobe could buy windows and the new AI Improved Adobe Windows could come with a lot $49.99 monthly sdudscription fee.

      • They're going to do it. It's not going to be a success. Everyone will riot. Satya Nadella will have to flee the country.

    • They'll probably go for the ad-free subscription model first, and then slowly put more and more things behind that paywall.
    • This already is the case. Your license is tied to your account as is your PC. You can use your Microsoft account to move a windows activation license from one PC to another. And if you subscribe to Microsoft 365 that is also tied to your account.

      I'm not sure what you think the purpose of these accounts are, but this is literally why they exist. Tie products and hardware to people.

    • Thought they already store the key in your MS account, they were talking about doing a cloud-based Windows (Windows doesn't exist as an installed thing on your computer, functions like booting a PXE).
      Hence, why I'm staying on Win10.

  • The only time I've had to do phone activation is for activating Terminal Service Licenses for Citrix clusters in enterprise. I wonder if that will also be affected or not.

  • Can MS F themselves and their "customers" (unwilling slaves) harder than they already have for all these decades? Omarchy or Arch or other Linux FTW. Gaming performance is now !excellent! on Linux using Steam and various emulators, including Windows games, even if not quite on par for certain titles. The remaining issue is games that use certain activation/anti-cheat software which doesn't run on Linux at least for now (F1 2024 for ex,).

    I have to maintain a variety of air-gapped boxes that run win 7, and two even still on XP.
    After that date, manufacturers got smart and most everyone shipped Linux based control systems, but it took them a while, and still to this day not everyone has.
    They are going to have to have some way to allow new installations of legacy versions.

    • I know of several legacy industrial systems running DOS, as they depend on software with built-in drivers which must communicate with long EOL ISA or PCI interfaces. It's expensive, but there are sources for legacy hardware (as well as old surplus) for this very market. Yeah you might pay USD$10K for a machine capable of reliably booting MSDOS 3.3, but it's cheap compared to the $250K CnC lathe or mill for which there are no more modern controls.

      Well, I know people that had to move off Windows as an industrial controller (which is pretty stupid anyways), because they need a network connection and Windows update was slow enough to kill the bio-rectors controlled.

    • They are going to have to have some way to allow new installations of legacy versions.

      They will not. A non-activated offline Windows presents no problem for such machines. The fundamental limit to an inactivated version of Windows was that it was blocked from updates and that it set your wallpaper black. The former doesn't matter (out of support), and the latter ... whop-de-fucking-do.

    • I think people are completely misunderstanding the change here. You can still offline activate you just can't do it by phone. You can go online (on a seperate computer and enter the code and get an activation) or if you are a enterprise or gov you are unlikely to be using phone activation and instead will be using a MAK or a KMS server. the only thing that has changed here is you can't use the phone as a method.

    I still have some old machines that have no network card. They might still have dial-up modems. Does a drive failure then "destroy" those machines from being what they were. I want to keep them exactly as they are (they are backed up)--I don't want to put Linux on them, for example.

      What are you doing wrong that windows phone activation comes into play when you replace a failed drive and restore a backup to it?

  • How different the industry would be if it were mandated that OS vendors, and maybe even social media, could only take revenue (or any form of consideration at all) from users. No other sources. No ads, no selling data, no backroom deals or agreements with other vendors... nothing.

    Because the GDPR forbids a need to create an account unless it is needed. Windows does not need an account.

    Well, maybe another $500M fine will remind Microsoft that the law applies to them...

    • They'll just eat the fine and continue. If they get fined they can also state EULA violation and shut off all M$ logins in the EU combined with a bitlocker key change that isn't registered in the TPM and ask for a recovery fee of $10k per computer and login.

        Haahahaha, no. If the illegal behavior is not stopped, there will be a 2nd fine and after that a prohibition to process personal information of any kind. That would mean their accounts become illegal in Europe. If they still continue, company representatives can get arrested and infrastructure seized and switched off. At least step 3 has happened to some company, I think in Greece. They are not even allowed to do their own HR anymore.

        MS has no choice but to comply.

    • False, it does no such thing. You seemingly have no idea how the GDPR works. What it does do is set a sunset time on any user related data assigned to an account, kept "no longer than necessary". It also prevents the requirement to force an account on a user at a later date that didn't exist at the time of purchase.

      Not only does GDPR not preclude the requirement for an account to use a product, given several of Window's advertised features don't actually work without an account you're wrong about the "need"

      • This is slashdot, it doesn't matter how inaccurate his rant was, it was anti MS so it will get modded up even though it should be modded down into oblivion.
  • There is no recourse for when online activation breaks. I used to call that number and explain: my effing hard drive died // or Windows cruft crashed so I need to reinstall on the same pc -- and they'd say, ok, use this new code instead. Now I have to buy a whole new motherfucking license.

    Yes I also use Linux but sometimes I need to use Windows Apps because they're the ones that can access my data.

    I can actually provide a bit of insight on this. It's because it got cracked on every version of Windows and Office that supports it going back to like Windows 7. This happened nearly a year ago now. I'm not sure whether Slashdot wants me posting direct links to websites that host crack tools so I'm not going to do that, but if you search mas blog tsforge you'll find their writeup on what it is and how they did it. It's a fairly interesting read.

    The writing's been on the wall for phone activation since then. I don't think they're going to bother patching it out of old versions of Windows but it was pretty obvious they were going to drop support for it at some point since it's so completely and utterly busted open.

    Thankfully, I have nothing to do with Windows clients other than being forced to use them as a client for filing my hours in an accounting program. But, the environment I'm in has what I suspect is a few tens of thousands of Windows virtual machines. We are mostly a Linux shop, but there are many tasks where only Windows will do.
    I'm guessing Microsoft has provided us some sort of offline license activation server because there only legal method of moving data on or off this network is to copy it to a USB device, send it to a department who then scans its contents on a machine which is read-only and boots from network freshly for each task. Once the content is validated as safe, it is sent to the next machine which is virus and malware scanning. You can't send data in unapproved container formats like RAR. And then the USB drive is moved to the correct isolated virtual network and transferred into the isolated storage.
    We are far from extreme compared to other environments I've encountered. I have worked in a place where, by Cisco's guidance, we were forced to fill the USB ports of Cisco equipment with epoxy because there was no way to disable the ports otherwise.
    I think that either Microsoft has decided that they would issue offline licensing methods for special cases or that they wouldn't mind losing this kind of business.
  • I noticed this last year when trying to activate an old copy of MS office 2013.
    I guess you could argue that I shouldn't be using an old unsupported copy, but this is for use in a non internet connected system.

    This kind of abuse of a monopoly needs to be checked.

  • Not going to work very well on air-gapped networks.

  • I had a look at the link provided. It looks like MS is providing an offline activation via a web portal, rather then a phone number.
    if you have an air gaped machine, you can use the website from your phone (it looks optimized for mobile, even on my desktop) to do the offline activation.
    This has to be way better then doing it via phone.

    Put the pitchforks down, MS isnt forcing machines to connect to the internet to activate, and they arn't really ending the service, just making it less dumb.

The best laid plans of mice and men are held up in the legal department.
