Matt Wrock has done a lot of work on this for Windows. https://github.com/mwrock/packer-templates He's got some great Powershell scripts he runs to help reduce the size of his Windows images. I haven't tried these specifically using the amazon-ebs builder but the idea is the same. Specifically he's got a provisioner script he runs that removes a bunch of features, cleans out logs and caches, and zeroes out the rest of the empty disk https://github.com/mwrock/packer-templates/blob/master/scripts/provision.ps1
