How is the solution always showing that the computer is shutting down?

Some students found that when the shutdown was turned off, what is going on? How are we going to solve this?

Solution One: Click on "Attachment-> System Tools" in the "Start" menu, then click "Disk Defragmenter" under the secondary folder to open, the general computer for a long time without disk defragmentation cause the computer shutdown is slow.

After you open the program, select C, and then click the "Disk Defragmenter" button to analyze and defragment the disk fragment on the C disk. After finishing, you can here the other disk fragments, the same method.

When there are too many programs running on the computer, shutting down will make the shutdown very slow, you can close all running programs, and then click the Start Menu "shutdown" operation.

You can shorten the waiting time for the program to shut down automatically after the shutdown. Click on the "Start" menu button to open the "Run" program, or you can use the key combination Win+r key to open.

When open, type "regedit" in the text box, and then click OK to open Registry Editor and navigate to the Hkcy_current_usercontrol paneldesktop node.

Workaround Two: Locate the Waittokillapptimeout key value on the right, and then double-click the key to enter a value of 3000 in the form that pops up, that is, the wait time for the shutdown program is 3000 milliseconds, or 3 seconds.

This is shutdown when there is a panic, if not often, press the shutdown button off the machine just. If it happens frequently, you can test whether the CPU temperature is too high, if the HD is gray. General play or operation time is too long will appear shutdown, if it is so press the shutdown button off the machine. In addition, before the failure to download what software, Plug-ins, drivers, upgraded the patch did not, if there will be all of them to uninstall try. Turn off all open programs before you shut down the computer. Or not, download win cleaning Assistant kill Trojan, restore the system or reinstall (in addition whether the hardware or hardware has been upgraded to the problem, some people installed 360 guards, Sogou input method, etc. will be so, uninstall can be restored).

This problem is the software conflict, drive inappropriate, system problems caused, can restore the system, or do not reinstall the operating system, do not install software, patches, drives, etc., see the boot still have problems? If there is no step-by-step installation of drivers, patches, software, find the wrong things do not install.

If you are unable to resolve the shutdown problem for the time being, shut down the computer. Right-click the task bar selector/Task Manager, hold down CTRL while you click the "Shutdown"/"close" button on the Task Manager page when you release the CTRL key to wait for the shutdown (I shut down the machine for five years, so the shutdown is safe and fast).

Automatic shutdown is a more complex process, which is performed by the system process CSRSS and Winlogon and calls the shutdown function Shutdownsystem. This function further calls SetSystemPowerState to close the driver and other current execution subsystem (such as Plug and Play manager, Power Manager, executor, IO Manager, Configuration Manager, memory manager, etc.). In addition, when performing an automatic shutdown, the system also checks the status of various external devices in the current system and the status of applications that have not yet been closed, processing data in each data buffer, and so on. If there is an error in the above work, it will not shut down properly. As a general rule, all peripherals should be stopped before shutdown, and all applications should be shut down.

If this is the case with your computer, you can do so in the way mentioned above.
