You can store it in
* an INI file
* the registry
* a database
* a text file
* any other format you like

but you have to write it out somewhere. examples of all the above can be
found by searching under http://groups.google.com

BTW, it's generally not good form to put the question in the subject as many
people won't see it, especially if they are using the up/down options in
their newsreader.
