I work in the Oil industry, I have 1 specific system that runs a diagnostic application for a particle widget.
The systems is logically disconnected, and is sent out with Windows 10 Ent. Activated.
In the event of an issue, "hard-drive failure, or full computer failure" I can replace with either a backup image, or replacement parts.
When this happens my Windows 10 is no longer Activated.
Here is the tricky part.
Phone service is minimal, there is a satellite phone but normally used for emergencies.
So activation would be - NO KMS , -NO INTERNET, -NO PHONE.
I have called Microsoft with this question, they said those are the only 3 options. I get the SAT/phone is my only real option but thats why I am sending this scenario out to the community.
I have valid KMS and MAK Keys for the OS... Just need a way to activate windows without using Microsoft's 3 approved methods.
