Office Web Apps 2013 and Update KB2760445


We've got Office Web Apps running through sharepoint 2013 and this update keeps coming up. Every time we've run the update and tried to use web apps again we get Server Error and a notification that the error has been logged to the administrator. We've had to uninstall and reinstall webapps to fix the issue.

Any idea what's happening?

Here is an update to this issue that I've posted to the Office IT Pro blog.  I'll update the TechNet article as well.

3/22 update: The March update was initially released as a critical update.  This caused it to be released via Microsoft automatic updates.  If you had automatic updates enabled on your Office Web Apps Server this caused some grief.  We heard the feedback.  The March update is being reclassified so it will not be automatically applied.  We'll be looking at the future updates as well to prevent this issue from occurring again.  However, be aware that any security updates that are released could be automatically applied by the automatic updates process.  So, for now, keep Microsoft automatic-updates turned off on your Office Web Apps Server.  And, if you use Windows Server Update Services, then you will need to download a new catalog with the re-classified Office Web Apps Server update.  Apologies for the trouble!
