They've got their own version of Windows and licensing. They're not running Windows 10 Home lol. They've got their own LTSC type thing. DoD works directly with Microsoft. None of this applies to them.
I have worked in National Defense, held a security clearance, etc. and can confidently say you are mistaken.
Microsoft is not maintaining a separate build of Windows for DoD. They may have bespoke licensing agreements and support contracts, but military and DoD workstations run regular windows.
They are, however, maintaining a separate cloud, and parent is not mistaken; windows professional running under group policies is a different animal than windows home
>> Subscriptions in the GCC High and DoD environments include the core Exchange Online, SharePoint, and Skype for Business features. Given the increased certification and accreditation of the infrastructure, there are some feature differences between the general commercial Office 365 offerings and those available in GCC High and DoD.
I'm not going to get any further into it, but the only one who mentioned "windows home" was the other poster, in an attempt at reductio ad absurdum.
Whether or not "windows professional with group policies" constitutes "their own version of windows" as per bongodongobob is left as an exercise to the reader.
They said version of Windows, you said there's not a separate build
Okay, it's the same operating system, but DoD managed devices have a different set of features and capabilities that are allowed to run on that device so I would contend that counts as a different "version", if the disagreement is semantic so be it
