  I figured this update had to be installed asap, so I quickly glanced through the WSUS deadline library article here:technet.microsoft.com/.../cc708585(WS.10).aspx The article doesn't say that a deadline takes precedence over the "No auto-restart for scheduled automatic update installation" policy.Well, actually I expected it would take precedence over the policy and so it was no suprise to me my phone was ringing soon after I applied the deadline.What I didn't expected was: in this kind of scenario, Word 2003 shuts down and throws away all data INCLUDING auto recovery data files. I expected Word to block the auto-reboot by popping up with a "save as" dialog or at least keep the auto recovery data.Clearly my bad. However, I'm sure I'm not the only person that got hit biy this behavior.
