1. Supply the code given by the "slmgr /dti" command to Microsoft over the phone or online from a non-air gapped machine.
2. Apply the resulting activation code with the "slmgr /atp" command.
Even in Enterprise by the way. No way we pay the amounts listed on the MS website.
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"
It does require logging in (to the website) with a Microsoft account, but Microsoft claims: By logging in with your account, it will not associate the account to the licenses.
From there, it's just a web version of phone activation (you enter your Installation ID and presumably they give you the Confirmation ID). No idea what happens when moving a licence between machines (with phone activation, the automated process would fail due to the existing activation and you'd be handed off to someone in a call center who would generate the Confirmation ID for you).This is a small roadbump to home/smb free activations.
Or a Windows 11 IoT image, that only enables some specific features, and is stripped down for a specific purpose.
For individual use I guess the solution is to set it up once with internet connectivity and air gap afterwards.
That's simply not good enough for some purposes. Once a computer is connected to the internet, at all for any amount of time, the system could be considered to be less secure.
VAMT proxy activation is airgapped in the exact same way the “old” telephone way was; VAMT acts as the server that you used to call on the phone. It trades one token for another. You side channel the tokens across to and from the airgapped machine.

Only risk would be to not have suppport available.
I knew a number of companies who were using a handful of RedHat servers and many more running CentOS and whenever they encountered issues on a CentOS system they would just replicate it on a RedHat one before asking for support and sending logs. Morally dubious but contractually OK.
Edit: We only wanted to buy around 20 licenses, so their motivation was also not that big to figure it out.
Is it possible to activate via a web browser on a separate computer, similar to the flow for phone activation?
