Autoruns : sdelete

We are using vmware view with Atlantis ILIO solutions, following atlantis best practice we configured our windows base image with a scheduled task that run sdelete every night in order to delete unused storage blocks saving storage space on our SAN.

Unfortunatley sdelete need to run once in order to accept the EULA, this cause the scheduled task to stuck waiting for a user input that will never come.

Does someone know if there is a method to avoid the initial sdelete message ?

Thanks to everybody
