Recently, some czech guy did a traffic analysis of data produced by Windows 10.

Results:
-It sends all text you type anywhere (not just into search) every 30 minutes to MS. If you type about a holiday to your blog, next day youll see holiday ads.

-every 30 minutes it sends your geolocation and network info

-if you type a telephone number into Edge it sends it to MS after 5 min

-if you type anywhere in windows a name of some movie, windows will start indexing all your media files after a while and will send it to MS after 30 minutes of your inactivity

-after installing W10, it will send about 35MB of data once

-after turning on your webcam for the first time it sends data to microsoft once. Probably your photo.

-everything you say is transferred to MS, it works even if you disable and remove and uninstall cortana. Parts of Cortana are needed for the core of the OS to run. Confirmed by MS helpdesk. You can be identified by your voice anywhere near a microphone after they get enough data from you.

-Voice to text is transferred instantly

-voice is transferred every 15 min, 80MB of data

-after 15 minutes of your inactivity or when screensaver is on, network activity ramps up and everything else is being sent to MS

-blocking in hosts doesnt work, IPs are hardcoded into their code and DLLs

Still need some sort of confirmation on that Czech article. Most of micro$oft products are crap anyway, don't use them :)

ok, so thats like 320MB/h = 7.68 GB/day .. I don't think so, because people without flatrate would recognize instantly.
And: lets assume that 7.68GB/day is sent by every user every day to microsoft.
Of course you don't run your PC 24/7, so lets assume the average person uses the PC for 3hours/day. That is still 960MB.
Ok, now lets assume 70% of all users have a microfone (that is a pretty realistic assumtion, as every tablet and notebook 's got a mic).
Ok, now lets go further and and lets believe this article. Currently 50mio users run Win10 (but it will be more in the future for sure).
So by now 50mio users * 0,7 * 0.98GB/day = 34,300,00GB/day = 34,300TB/day =34.3PT/day
So if your data is true, servers of microsoft would have to process, store, analyze and (in order to use that information later on) index all those data.
So.. Sorry, I don't think so.

And this was one only the voice data, it gets even more if you include text, location, telephone numbers, ..
Microsoft is big, but not as big as the Alphabet Holding (Google), so I don't think Microsoft is going to store all that data.
