How to turn it off?

How to shut down is the correct way to shut down.

Close all applications:

1, normal mode: start menu-turn off the computer;

2. Task Manager mode: Task Manager-Off-Off;

3. Shortcut: Open the Task Manager-Close it, then press and hold "CTRL" and click "Close";

4. Forced mode: press and hold the power button of the main machine, and hold several bills continuously.

The first item and the second item belong to the same shutdown, but the operation location is different. For the third quick shutdown, please visit my blog and see "The Mystery of Windows Quick Shutdown". The fourth item is completely abnormal shutdown, which is generally not desirable.

There are always people complaining that Windows shuts down too slowly. In fact, Windows itself shuts down very quickly. The problem mainly lies in the programs installed by users, and the shutdown delay is caused by some poorly designed applications or drivers. In order to solve this problem, the following techniques have appeared on the Internet:

When opening the task manager, hold down the Ctrl key, and then click the menu "Shut Down → Shut Down" command in the task manager window, and the system will shut down quickly. Similarly, when you hold down the Ctrl key and select another command (such as restart), the command will be executed quickly.

At the same time, there are also fast shutdown software like SuperFast Shutdown.

Before discussing the above technical principles, let's talk about how Windows shuts down: Windows shutdown steps involve multiple components and processes of Windows. Simply put, the Windows shutdown step is not as simple as most people think. The basic process is as follows:

1. After the user issues the shutdown instruction, the program that issues the shutdown instruction will notify the csrss.exe of the Windows subsystem. After receiving the notification, csrss.exe will exchange data with Winlogon.EXE, and then Winlogon.EXE will inform CSRSS.EXE to start the system shutdown procedure.

2. After receiving the notice from Winlogon.EXE, CSRSS.EXE will use the top-level window to query the user processes in turn and let them quit. If the user process does not exit within the default timeout of 5000 milliseconds (the timeout can be set by modifying the registry key HKEY _ Current _ User \ Control Panel \ Desktop \ HungapTimeout), Windows will display an "End Task" dialog box and ask the user whether to end the task. The dialog box will be displayed by default, and will not be closed automatically, leaving it unchanged. For console programs, the basic situation is similar, except that Windows uses the value of HKEY _ Current _ User \ Control Panel \ Desktop \ waittokillapptimeout to set the timeout.

3. Then it is the turn to terminate the system process. The system flow includes SMSS.EXE, Winlogon.EXE, Lsass.EXE, etc. When terminating a system process, Windows will not prompt the user if it cannot be terminated within the specified time, which is different from terminating a user process. Instead, it skips this process and terminates the next system process. The timeout used is the same as that used in step 2.

The above three steps are the most time-consuming part of the whole Windows shutdown process, and most of the reasons for the slow shutdown are caused by these three steps. After completing the first three steps, enter the fourth and final shutdown operation.

4.Winlogon.EXE calls a local API function NtShutdownSystem () to command the system to perform finishing work. At this stage, the Windows execution subsystem will complete the final shutdown operation, for example, the device driver will complete some special operations of driver settings at this stage; It is also at this stage that the configuration management system writes the modified registry data to disk. After all subsystems except power management exit, power management completes the final operations, such as restart and shutdown.

How to shut down quickly?

On fast computer shutdown (an alternative method of computer shutdown) 1. WindowsXP 1。 Make a close file.

Create a new file on the desktop with notepad file, and enter "(New Active XObject ("shell. Application ")). Close Windows 0 (don't enter quotation marks, the same below), then close the save and rename it "shutdownsj", so that the file can be closed every time you double-click it with the mouse. 2. countdown to shutdown.

Enter "Shutdown -s -t 30" during startup → operation, and confirm that it can be shut down after 30 seconds, where 30 is the countdown to shutdown, or you can customize the input. If you want to cancel the countdown shutdown, you can enter "shutdown -a". 3. Turn it off regularly. Create a new "shortcut" on the desktop, and enter (the default installation disk is disk C) in the wizard "Location": c: \ Windows \ System32 \ tsshutdn.exe1powerdown/delay: 01,where 10 is the delay time of shutdown.

In fact, at this time, the planned shutdown of the mine needs to add this "shortcut" with the "plan task" program, and then set it as the shutdown time of XX, such as 22:00 at night. You can also directly enter "at xx: xx shutdown-s" during startup → operation (xx: xx means downtime).

In windowsXP, you can set the shutdown. Enter "Shutdown-i" from start to run, and the Shutdown Settings window will pop up, where you can set "Remote Shutdown", early warning time settings, planning options, etc. It depends on your settings. If you want to get more shutdown skills, you can use "shutdown-help" to query. Note: If you want to perform countdown or scheduled shutdown in windows2000, just copy the "shutdown.exe" file in the directory of windowsXP c:\windows\system32 to the directory of Windows2000 c:\winnt\system32. Second, windws98 can modify the registry in windows98 to realize fast shutdown.

1. Enter regedit in Start → Run to open the Registry Editor. 2. Expand it into HKEY _ class _ root \ directory \ shell branch.

3. Create a new primary key named Close and change the key value of "default" under this primary key to "Quick Shutdown". 4. Then create a new primary key named mand under the Close primary key, and change the key value of "default" under this primary key to Rundll32.exe user.exe to exit Windows.

Then save and exit Registry Editor. 5. Restart the system. Click the "Start" menu with the right mouse button, and you can select the "Quick Shutdown" item in the pop-up right-click menu to shut down the computer.

Hazards of Fast Shutdown There is a fast shutdown method circulating on the Internet: call up the task manager, hold down the Ctrl key, and click Shutdown, which can be shut down in three seconds, which is very fast. In addition, there are some fast shutdown softwares, such as SuperFast Shutdown, which can also be used for fast shutdown.

As we all know, when the system is shut down, there are a series of operations, including closing windows, ending processes and services, saving data and so on. Also, does it save some steps to shut down as quickly as above, and will it cause harm to the system? First of all, let's take a look at the steps to go through when the system shuts down normally: ① notify the Windows subsystem CSRSS. EXE，CSRSS。 EXE shutdown instructions, and exchange data with Winlogon.EXE after receiving the notice, and then Winlogon.EXE informed CSRSS.EXE to start the system shutdown process.

(2)CSRSS.EXE queries user processes with the top-level window in turn, and lets these user processes exit. (3) Then start to terminate the system process.

The above three steps are the most time-consuming part of the whole Windows shutdown process, and most of the reasons for the slow shutdown are caused by these three steps. (4)Winlogon.EXE calls the function NtShutdownSystem () to command the system to perform the following finishing work and finally close it.

It seems that the Windows shutdown process is quite complicated. However, using the Ctrl key to shut down or using some quick shutdown software does not go through the complete four-step process, and often skips the first three steps and directly calls the NtShutdownSystem () function to shut down.

Many software will write data into memory when it is running, and then save it to a file when it exits. If you shut down the computer without going through the previous steps, the program will not quit normally and the data will be lost, which may lead to some unexpected errors due to the loss of important data, which is harmful to the system.

Therefore, I suggest that you try not to use the Ctrl key to shut down or some fast shutdown software. After all, data security is much more important than saving shutdown time.

How to turn off the computer?

Turn off the computer in one second.

Windows XP not only starts slowly, but also shuts down quickly, and it takes a long time to shut down completely every time. Here is a hint for you to turn off your computer in a short time.

Step 1: in Windows XP, press Ctrl+Alt+Del to open the task manager window.

Step 2: In the Task Manager window, hold down the Ctrl key, then click the left mouse button on the menu "Shut Down" and click "Shut Down" from the menu, and the computer will shut down immediately.

Sometimes, we need to turn off the computer regularly. Here, the author introduces a simple method to turn off the computer regularly under Windows XP.

After 22 minutes, the system will shut down automatically: click "Start → Run", enter the command "Shutdown -s -t 1320" in "Open" (note: there are spaces between parameters without quotation marks, and the unit of 1320 is seconds), and then click "OK".

Specify that the system will automatically shut down at a certain time (such as 12:00): just enter the command "Shut down at 12:00 -s" in "Open".

Cancel the planned shutdown: Just enter the command "Shutdown -a" in "Open".

The function is realized by using the "shutdown" command, and the shutdown parameter is to enter "shutdown" in the command line window. The author thinks that the most useful parameter is "-i", which can call up the "Remote Shutdown Dialog Box" and conveniently realize the remote shutdown of computers in the LAN. Interested friends can try it.

Two skills of closing Win XP quickly

1. Close with Shutdown.exe program.

Shutdown.exe is a shutdown program saved in the folder C: \ Windows \ System32 (drive C is the system disk). Create a shortcut for Shutdown.exe on the desktop, right-click and select Properties from the pop-up menu. Add "-s -t 10" after the path of the "target" text box in the properties dialog box, where "-s" stands for shutting down the computer, but it can be changed to "-r" to restart the computer; "-t" means to set the countdown time, and the following number "10" is 10 second. Readers can modify it according to their own needs, which can greatly reduce the waiting time for shutdown.

Another parameter is "-c shutdown display prompt message", that is, when you want to shut down, a message showing your settings will pop up. Please note that the shutdown prompt message cannot exceed 127 characters.

2. Make good use of Task Manager

In Windows XP, press "Ctrl+Alt+Del" to call up the Task Manager window, press and hold the "Ctrl" key while activating the menu "Shut Down", and then select the menu item "Shut Down" or "Restart". At this time, you will find the window.

The shutdown speed of XP can be said to be instantaneous.

How to force the computer to shut down?

1, power key:

Each computer is equipped with a power button, which can be turned on or forced off. Just press and hold the power button for more than 3 seconds to force it to turn off instantly.

2.Ctrl+Alt+end (only for computers with the end key on the keyboard)

This method can realize instant shutdown, but it does great damage to the hard disk.
