My girlfriend's got windows 10 on her computer, the other day she asked me if I could fix the start menu for her. I hadn't really looked at it before then. It was full of crap she didn't install, there was a popup in the bottom corner advertising for an office 365 subscription. She just wanted me to get rid of the tiles. There's no option for this, only an option to make them bigger. So in the end I sat and manually removed them. 2/3's if them were were links to crap like Amazon and eBay, candy crush and other shit that just came preinstalled. Nothing she actually uses on her computer ever ended up pinned there.
