The data is priceless! The breakdown of the quick shutdown of the

  

On the Internet, I saw some ways to quickly shut down the computer: call up the task manager, hold down the Ctrl key, and click to shut down, so that it can be turned off in three seconds, and the speed is very fast. I tried it and it was very quick to shut down, so I used this method often when I shut down. However, the time is not long, the computer has appeared several times, often prompting the program to run incorrectly or unclearly lose some files, why is this? In fact, they are all caused by a quick shutdown. We know that a normal system shutdown requires a series of operations, which generally include four processes: closing the window, ending the process and services, and saving the data. However, the quick shutdown saves some steps, so it is harmful to the system. The four steps of the normal shutdown of the system are: the shutdown command notifies the Windows subsystem CSRSS.EXE, CSRSS.EXE, after receiving the notification, it will do a data exchange with Winlogon.EXE, and then Winlogon.EXE notifies CSRSS.EXE to start shutting down the system. The process; then CSRSS.EXE in turn query the user process with the top-level window, let these user processes exit; then start to terminate the system process; finally Winlogon.EXE calls the NtShutdownSystem function to command the system to perform the subsequent sweeping work, the computer shuts down normally. The use of the Ctrl key, but often skip the first three steps and directly call the NtShutdownSystem function to shut down. As we all know, many software will write data to memory at runtime and save it to a file when it exits. If you do not go through the previous steps, it will cause the program to not exit normally and lose data. This may cause some unexpected errors due to important data loss, which is harmful to the system. After recognizing the shortcomings of the fast shutdown, the fast shutdown has never been used in the future. After all, the security of the data is much more important than the saving time. Here I also hope that everyone will try not to use the fast shutdown, or wait until the computer has problems and regret it too late. ;
