Right click on the "Windows" logo in the lower left corner. Select Control Panel. You get exactly the same control panel as you had in Windows 7 - and it's trivial to create users, add/remove programs, change hardware settings, etc. Try it - it's pretty darn simple!
As far as starting stuff up, I have several of my more oft-used programs pinned to my taskbar, and several links on the desktop. Compilers, CAD packages, MATLAB, all pretty easy to get to, and simple to run. Seriously, there is VERY little difference between the Windows 8 desktop and Windows 7 desktop. You do not need to use the Metro UI if you don't want; I rarely use it (other than the quickly access little-used programs, a couple times a week).
All seems condemned in the long run to approximate a state akin to Gaussian noise. -- James Martin
