Just click the Windows icon in the lower left corner of the desktop, and then select "Shit Down". Of course, in some cases, the icon may be hidden or moved to another location. At this time, you need to open the task manager to find it.The method is as follows: Ctrl+Alt+Delete→Task Manager→File→New Task (run)→Enter "shutdown -s -t 0"→OK. 3. Use the command prompt to shut down. If you find the above two methods more troublesome, you'd better try to use the command prompt to shut down. Just press Win+R, and then enter "cmd" to open the command prompt. Then, enter "shutdown -s -t 0" to achieve a quick shutdown. Among them, "-s" is the shutdown command, and "-t" is the shutdown delay time, which is in seconds. Here, "0" means immediate shutdown. Of course, if you want to shut down after a certain time, you can set a time value by yourself, for example, "shutdown -s -t 3600" means shutdown after 1 hour.Four. Before shutting down the backup data, it is recommended that you back up important data first. This can avoid data loss due to computer failure or other circumstances.

Before shutting down, be sure to close all running applications. This can not only ensure the security of the data, but also avoid anomalies in the next startup of some programs. The way to close the application is very simple. Just press Ctrl+Alt+Delete, then select "Task Manager" and close all running applications in the "Process" tab. 6. Waiting for automatic shutdown If the CPU overload fails to shut down normally in the Win7 system, you can consider waiting for the system to shut down automatically.Under normal circumstances, the system will automatically shut down within 5 minutes. You can also select "Shutdown does not update" in the "Shutdown" option of the Start menu. However, it is recommended that you do not update. Before entering the hibernation state, you must update all programs and system files to ensure the normal shutdown. In a word, safe shutdown is a very important thing in the Win7 system. The methods introduced above can help you achieve a safe shutdown. However, before using the above methods, you must realize the importance of backing up data and closing applications, so as to avoid data loss and system abnormalities.
