Microsoft Snooping on PCs without users knowing about it

Normally I implement most Microsoft Office patches without getting into fine prints, but the latest one spooked me completely. Here is a screenshot.

Want to read it verbatim? It says:

Microsoft has released an update for Microsoft Application Error Reporting. This update fixes an issue with Microsoft Application Error Reporting that may cause some information about application errors to be sent to Microsoft without notifying you.
More information for this update can be found at http://www.microsoft.com/downloads/details.aspx?FamilyId=EE28696F-0826-409F-9B1C-781D28BB5981&displaylang=en

That means Microsoft had been getting data from My MS Office about crashes without me knowing about it.
