I have experienced the same problem, and I just managed to fix it.
From my experience, it is caused by one or more not-well-designed background processes in your system, but I think everyone has different processes causing that program, so you have to find out what's the exact wrong process in your system. For me, it's a process called Grid service.
To check which process is wrong, I suggest you open task manager, switch to Processes tab, manually close a suspicious process and try to shutdown win 7. If your win 7 can shutdown correctly, then you know which process is wrong, otherwise, repeat this method by closing another suspicous process until you find out the reason.
Once you know which process is wrong, you may consider uninstalling a related program or disabling it from start-up to get rid of the problem.
