If you install Classic Shell (windows classic start menu) you can find everything again where you once learned it would be (in fact you can configure it the way you like)
I use the same on all MS desktops inc. 10. It puts all the things you need right back into one menu
Hated it when MS started to think a desktop was really an ipad
