Greedy speed, the danger of using shortcut keys to shut down

Ask everyone what kind of way to shut down? Someone used the start button to start the above, some people use the shortcut key of CTRL+ALT+END, of course, there are other ways. But have you ever thought about whether there is any harm in using the shortcut keys? I like to use ctrl+alt+end to shut down my friends and read this post. Do you still use it?

If it is not NT system, use CTRL+ALT+END to shut down directly. There are great disadvantages to the hard disk.

I saw an online shutdown method for 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. However, the time is not long, the computer has appeared several times, often prompting the program to run incorrectly or unclearly losing some files. Why is this? In fact, it is 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 normal shutdown of the system are as follows: First, the shutdown command notifies the Windows subsystem CSRSS.EXE, CSRSS.EXE, and will receive a data exchange with Winlogon.EXE after receiving the notification, and then notify CSRSS.EXE by Winlogon.EXE. Start the process of shutting down the system; then CSRSS.EXE in turn queries the user process that owns the top-level window, let these user processes exit; then starts to terminate the system process; finally

Winlogon.EXE calls the NtShutdownSystem function to command the system to execute the following After the work is finished, 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, the program will not be able to

exit normally and lose data, which may cause some unexpected errors due to important data loss, which is harmful to the system. After realizing the drawbacks of fast shutdown, I have never used a fast shutdown. After all, data security is much more important than saving the shutdown time.

After reading it, I don’t know what it’s like, whether it’s time to endure or speed shutdown. It’s good to use shortcut keys, but in general it does more harm than good, so use this method. Users have to think twice, I hope to help everyone,
