Unless you decide to move to Linux/OSX, would recommend you to migrate to Windows 10.

You can stop lots of upload by disabling Cortana and other cloud features, but you can't be 100% sure of what data is leaving your system. On other hand with popularity of cloud services and mobile sending all data back home, overall privacy feels like a lost cause.

Win 10 gives substantial performance improvements, new features and also developer experience is so much improved. Most the kinks of UI are sorted out, and it feels much more polished and at home on a laptop.
