Hi davidem123, thanks for the post. I’d like to inform you that if the shutdown is dirty, Windows Disk Protection will revert to discard mode. When the system is not shut down normally, WDP reverts to "remove all changes at restart" because the disk is not guaranteed to be in a consistent state under those circumstances. This is by design. We will see if this can be improved in the next version.
Thank you for your understanding.
