25,000 "events"
>>>Microsoft tracks around 25,000 different types of "event"...techies are also able to add new events to be recorded<<< how many types of events are left?
The report is worth reading.
>>>until recently there were no central rules governing the collection of the Office telemetry data<<<
>>data may also include the content of a query sent to search engine Bing, or the content of text you want to have translated. In that case, Microsoft may collect the sentence before and after the sentence you mark for translation, to provide a better translation.<<<
Talking about targeted recommendations (adverts) >>>protect the monetisation of the Office product, and we accept we have to disrupt the attention of the users.<<< basically MS admitting in writing that trying to get more money out of the punters is more important than letting them use the ones they've paid for already.
I'll refrain from expletives, they're not adequate to convey the contempt.
