I already had a registered user, and I loged in with a new account and click on the option "Don't ask me again" and after the reboot, I loged off and loged in with the same user account and it did not promt me.
I then unregister the original user also from the SEE and rebooted the machine. It promted me to register now or cancel, there was not option for "Don't ask me again".
hope this gives you some idea.
