Monthly catalog and actuall downloaded patches

Hello,

Would you please advise if the monthly security update catalog from Symantec and actuall downloaded security updates from Microsoft are all for windows 2003, 2008, 32-bit, and 64-bit?

Also, Altiris NS is smart enough to deliver 32-bit  security update to 32-bit servers and 64-bit security updates to 64-bit servers, isn't it?

Please advise.

Thank you,

Charlie.
