Shutdown process

Hi everyone,

I've got a good handle on the startup process (BIOS self test, loading of the OS, loading of application software - actually I have a more detailed knowledge than that, but you get the idea), but I don't know what happens during the shutdown process. Can anyone tell me what my computer is doing when it's shutting down. I just know that it doesn't take as long as startup, but I have no idea what it's doing. I've tried to google it, but all the sources I find has to do with trouble shutting down. I don't have any trouble; I'm just insanely curious about what's going on.

Thanks in advance for your shared knowledge on the matter.
 
Basically the OS issues the shutdown command and kills all running apps and services. It then saves any changes made to the OS, then powers off the computer.
 
Shutdown process:

-attempting to exit/close all open programs/applications
(if an attempt fails,you are asked wether or not you want to terminate the process of the program/application)

-attempting to exit/close all background programs/applications
(if an attempt fails,you are asked wether or not you want to terminate the process of the background program/application)

-saving any changes you have made to the operating system

-attempting to exit all the driver executions
(if an attempt fails,you get an error message which usually displays the technical numbers and other informations.Sometimes the computer restarts instead)

-attempting to stop all operating system processes
(if an attempt fails,the shutdown process sometimes blocks and never shuts down the computer and sometimes you get Windows error message displaying the reason for the error)

-attempting to clear all the resources from the RAM memory chips
(if an attempt fails,you usually get an error message which says that the memory could not be READ or WRITTEN)

--->If all the steps executed correctly,the computer will shutdown completely.




Cheers!
