Weird. Couldn't get KMS2038 to do it for me on 25246. Installs its own key, then at the end just tells me it's in notification mode.
I noticed you edited some of your posts and still it doesn't show the expiration date bypassed and now you use KMS38, that's not KMS_VL_ALL by @abbodi1406 and the expiration date is not bypassed by it, it just shows the standard activation time for KMS38 activations.
