Knowing that every month Microsoft releases patches to patch security holes amungst other things.

After reading about the Ping of death atack at http://searchsecurity.techtarget.com...822096,00.html

I noticed a link to a definition for jolt, and near the end was explained that you must download a patch for windows 95 and 98 users.

I preform a Microsoft Update every month, being sure to check off the critical updates. My question is:

Does the critical updates patch all of the security vulnerabilities that they had became aware of, or are there seperate security patches that one must get?
