Windows 10 comes with a lot of Junkware that you didn't ask for and you might not need.
Here are some sites that give simple steps to follow to get rid of those things you may not need.
Removing One Drive
This has to be, for me, the most annoying thing. It sync on the cloud all your files on the cloud almost without clear consent. And if you do not connect to One it will annoy you until you do !
Removing Other Tools
Things like solitaire, bing news, bing sports, bing finance, etc... are for me totaly useless and uses my bandwidth, CPU and memory for no reasons. Honestly, why would you give bing maps as a default map tool, seriously ! It's like giving crayola to an adult looking to do photo retouches !
Anyways, go here to remove most of them : http://www.howtogeek.com/224798/how-to-uninstall-windows-10s-built-in-apps-and-how-to-reinstall-them/
Alas, some like Edge cannot be removed.
