I am a masters student from Louisiana, US. I have lots of passion on operating systems especially towards file systems. I want to know career path to get into windows core os group. My university dont have any research going on operating systems. May I know how to get started to become a good os programmer. Many people advised me to start programming device drivers initially .Is this a correct path to start ?? Since I dont have any projects in my university to work on device drivers how can I learn them ?? Even though I can learn from books Can I use them on my resume without having a project ?? Can some one provide a good advice for me to start.

Thanks & Regards,
