In my former industry, and my former line of work, we would never trust the integrity of an OS image on an SSD delivered from the manufacturer by standard courier (not e2e receipted CoC) without some means of verifying it on the receiving end e.g. checksum. Easy to do with network hardware, harder with PCs. Much simpler to just PXE-blast all the devices when they arrive.

It's quite a different world with Windows Autopilot pre-provisioning from the OEM. These images are customized to your specs, there's no Candy Crush shipping on pre-provisioned devices.

Windows Autopilot uses a PXE boot, where appropriate.
