These instructions may change slightly with each version, so it is wise to read up on what's required each time before proceeding. Note that the configuration is slightly different in each version.
http://www.jam-software.com/spamassassin/online_manual/EN/using_spamc_spamd.html provides more detailed step by step information. The below info is largely a digest of said info.
You'll also find a pre compiled version of SpamAssassin for Windows (inc. SpamD) that can simply be extracted and run here: http://www.jam-software.com/spamassassin/.
