The option to deploy the default .wim files provided by microsoft would be VERY MUCH appreciated!
There is a big advantage to using them for deployments as they can be very quick to replace to quickly have an updated base to deploy to minimize the updates technicians have to do on devices...
This also saves the admin time since this skips the sysprep-step.
(in our case for example we have no need for that since we just customize the devices accordingly after imaging with scripts)
