First, as always, when you shut down Windows, it's a good idea to have all the running program closed. With that said the new Windows 7 has improved "“force to close the program" area, where as in Vista, this process takes much longer
Second, we can do some tweak in the registry editor to speed up the shutdown timeout.
Start by going to the Start menu:
right click to modify
· Enter the new value 2000 (meaning 2 seconds, here you can enter anything between 2000 or above, by default this value is set at 20000)
Now you are done and ready to enjoy a fast shutdown on your Windows 7
