Dear Exchange team:

In your KB http://support.microsoft.com/default.aspx?scid=kb;en-us;924334 you state the following:

Restart requirement

You do not have to restart the computer after you apply this hotfix.

Uhhh.....wanna make a bet?

I get really annoyed with the Exchange team regarding their view rebooting.... if we have this on automatic update... we will read on the KB that we don't need a restart when we do... at least both the SBS-WSUS and the real WSUS does properly state that it may require a reboot

As you can see here...both state "can require restart"

So bottom line.... read the innards of WSUS ... as that appears to be a better definitive source of reboot/noreboot information.
