Here is an absolutely wonderful operating system development tutorial series by "Brokenthorn"... this helped me immensely in learning how to develop operating systems in Visual Studio, making working kernels and drivers as PE images (EXE and DLL files), configuring Visual Studio to compile properly, assemble assembly code, automatically deploy your kernel on your virtual machine for debugging and much more. It also has tutorials on implementing both basic and advanced graphics shells with working code and implementing a basic C Standard Lib and C++ runtime. It's awesome... trust me... :-)
