Hi Gus,

You are correct that the 2nd Tuesday of each month is when all new security
updates are released.

The 4th Tuesday of each month is reserved to distribute other high priority
updates, of which WGA Notifications (KB 905474) is classified.  All of the
WGA Notifications releases have taken place on the 4th Tuesday (1/24, 2/28,
4/25, 6/27).

The WGA Notifications update that we published on 6/27 is the general
availability release.  This release includes a revised EULA which is more
user friendly (and not all legalese) and based upon customer concern, the
removal of the download of the settings file which told the Notifications
app to run or not

KB 905474 is an optional update (published on the 4th Tuesday) and that is
why it does not show up in the June 2006 Security Update Bulletin that is
published.

We do realize that administrators (and users) rely on Windows Update to
keep their systems up to date.  We do not take this lightly.

When you have a free moment, take a look at this:
http://support.microsoft.com/kb/894199 - The target audience of this KB is
administrators who use WSUS (Windows Server Update Services) to maintain
their networks with secuirty patches, etc.

Find the link on the page for New non-security content and it will outline
everything that was published that is high-priority, non-security that was
made available on each 4th Tuesday release.

Let me know if you have any other questions or feedback and I will do my
best to assist you.

Thanks,
Michelle
