If you always intend to deploy within your organization, and license windows with KMS, is there ever a reason not to include skiprearm=1 in your various unattend files?
Seems to let me get more use out of my images.

Rearming Windows allows you to reset the grace period for activation on your clients. Since you're using KMS, there is no need for a grace period since the machine will automatically activate as soon as the KMS server is found.
In fact, you absolutely should always use
skiprearm=1 whenever you sysprep your images, because you are limited to three rearms.
If you attempt to rearm a fourth time, you will get an error. Thus, you can no longer make changes to this particular image and will need to start fresh. This can be a problem if you like to periodically roll updates into your OS image (like we do).
