We have several Dell laptops, each with it's own Windows 10 keycode. We would like to be able to deploy Windows 10 to one laptop with opsi, configure it, sysprep it, then take an image with clonezilla to deploy it to the others.
To try this, we deployed an unattended install to a laptop, did a sysprep, took an image with clonezilla, and then transferred it to another laptop of the same model.
When we booted the other laptop it went through the sysprep wizard OK. We got an error when we tried to change the keycode and activate:


We called Dell - they're saying that, without an Enterprise license, you can't legally image WIndows 10 from one computer to another, is this true?
