This talks about unattended installs yada yada. I go to CostCo, I buy a Windows 11 laptop, I turn it on. Does this xml file help me with this? I've done the "no internet" trick before, but does that still work?
This would not help you unless you were planning to reimage the laptop. It’s a tool that makes it easier to build custom images, which are usually deployed at scale in enterprise environments.
