I think you can get, and insert, a new registration code from Alwil anytime, regardless of how much time is or isn't left on your previous registration.

Mike,
You are essentially correct. For continued Home use at the end of the 14 month period, re-registration is required. You can do this at any time before the expiration.

Runner,
Before we all go “wild” with this key code thing, please check the setting of the system clock. If the clock was not set when the drive was formatted, Avast will not know the correct time period left to the expiration date.
