Microsoft s patch releases are predictably cyclical. January saw 2 bulletins, followed by huge February with 13, and then this week we saw just 2 again. In just the first three months of 2010 we ve already had wild swings in the number of CVEs and bulletins. Since March was a pretty light Patch Tuesday, we can expect that the bulletin count for April will jump back up into double digits. This month is your chance to catch up from January’s patch release.
