On the Internet to see some of the computer fast shutdown methods: Pull up the task manager, hold down the CTRL key, click the shutdown, so that three seconds off, fast. It was a very fast shutdown, so it was often used when shutting down the machine. But the time is not long, the computer appears several times the problem, often prompts the program to run the error or the loss of some documents, this is why? In fact, the trouble is to shut down the machine quickly. We know that when a normal system shuts down a series of operations, typically including closing windows, ending processes and services, saving data four processes. But the fast shutdown saves some steps, so it's a certain hazard to the system.

System normal shutdown of the four steps for: shutdown instructions to notify the Windows subsystem Csrss.exe,csrss.exe, after receiving the notification and Winlogon.EXE do a data exchange, and then by Winlogon.EXE notify CSRSS.EXE began to shut down the system process; then Csrss.ex e sequentially queries the user processes that have top-level windows, lets those user processes exit, and then begins to terminate the system process, and finally Winlogon.EXE calls the Ntshutdownsystem function to command the system to perform the following cleanup work, and the computer shuts down normally.

And the use of the CTRL key, but often skip the first three steps and directly call the Ntshutdownsystem function to shut down the machine. It is well known that many software writes data to memory at run time, and then saves it to a file when exiting. If you do not go through the previous steps shutdown, it will cause the program does not exit normally and lose data, this may be due to important data loss caused by some unexpected errors, the system is harmful.

In recognition of the drawbacks of fast shutdown, after the use of fast shutdown, after all, the security of data than the savings that a little shutdown time is much more important. Here I also hope that we try not to use fast shutdown, or wait until the computer problems regret also late.
