Windows Central Question
Greetings wc 
I really want to upgrade w8.1 to w10 tp (through windows updater), but I'm a poor student and only have one computer that i need everyday. So do i lose any data or applications if i update and do all applications work? My python and c programming software must work. And how about steam games?
