Option #1: Quarterly update service
The quarterly mailed updates are no longer available. You may purchase updates yearly, or download updates via the Internet Security Reference.
Option #2: Yearly update, or update when you choose
You may also buy the program, and the most recent version of the database at any time, so if you would only like the new database once a year it would still only cost the price of the original program - $32.00.
Option #3: Yearly update via Internet Security Reference
You may also buy the yearly subscription to the Internet Security Reference, and download the Windows Magazine Cross Reference updates as they become available, at least quarterly, if not semi-monthly. Plus you get all the extra features available in the Internet Security Reference.
