Just finished a clean install of Windows 8.1 on my laptop, I've linked my laptop login to my hotmail account and since then it's been telling me that people have been commenting on my facebook photos and giving me twitter updates. At first I thought it was just scanning my emails and presenting them in a tile.
I've checked and I seem to be fully logged into both my facebook and twitter accounts but I haven't once provided my login details, my passwords aren't stored in my email, I haven't logged into either service via browser and I use an android phone.... how does it do this?
