Sometimes we download things on the computer and want to shut down automatically after downloading. How to set it? The following is the desktop computer setting regular shutdown method I sorted out for you. I hope it is useful to you!
Method 1: input the command to shut down
The desktop computer can be shut down regularly by entering the command. First, use the windows DOS command to start - run, and enter the computer regular shutdown command in the run command box to shut down regularly. Enter "at 22:00 shutdown - s" in the run command box, so that the computer will appear the "system shutdown" dialog box at 22 o'clock. By default, there is a 30 second countdown and prompts you to save your work.
Enter "shutdown.exe - S - t 3600" in the run command box, which means automatic shutdown after 60 minutes, and "3600" means 60 minutes. After setting, a countdown shutdown dialog box will pop up. How long it takes to shut down and modify it by yourself. After setting the automatic shutdown, if you want to cancel it, you can enter "shutdown - a" during operation. In addition, enter "shutdown - I" to open the dialog box for setting automatic shutdown and reset the automatic shutdown.
Method 2: one key to shut down
Right click on the desktop, select "new → shortcut" from the pop-up menu, then enter "rundll32.exe, user.exe, exitwindows" in the blank space of the command line of the dialog box, click the "next" button, name this shortcut "quick shutdown", and then click the "finish" button.
Next, right-click the shortcut of "quick shutdown" on the desktop, select "properties", and then set the hot keys on the keyboard according to your wishes in the "shortcut" column of the open dialog box, such as F8. Of course, you can also click the "change icon" button below to select a beautiful button for the shortcut. In the future, as long as you press F8, you will tell the system to "turn off the computer".
Another method is also relatively simple. Open Notepad, enter "REM this is a batch file", then start another line, enter "rundll32.exe, shell32.dll, shexitwindowsex1", and then save the file as a "shutdown. Bat" file and store it on the desktop. Then press the above method to set a shortcut for the file and specify the corresponding shortcut key, such as F12, to realize one click shutdown. This method is relatively simple.
Method 3: shut down with software
At present, mainstream anti-virus software, such as 360 anti-virus and Jinshan anti-virus bully, all have the function of automatic shutdown after virus scanning. We can use the function of automatic shutdown of anti-virus software after anti-virus scanning for a period of time to realize automatic shutdown of computer, which is quite simple to operate.
360 anti-virus software is selected to scan the whole computer for virus. Generally, the scanning time is about 10 minutes to 30 minutes. When we need to shut down automatically in a relatively short time, this method is more practical. At present, most anti-virus software have this function. However, the use of anti-virus software to realize the regular shutdown of the computer can only be determined by the time the anti-virus software scans the computer, which is not very convenient.

XIII. Reduce loading items at startup
Many applications will be added to the system startup group on their own during installation, and the system will run automatically every time it is started, which not only prolongs the startup time, but also consumes system resources after startup!
Start the "system configuration utility", list the items and sources loaded during system startup in the "startup" item, and carefully check whether you need it to be loaded automatically.
