How to achieve Win7/Win8.1 quick restart?

For Win7, Win8, Win8.1 users, rebooting the system is simple. If you encounter the above three situations, it is especially difficult to restart the system, especially if the system does not respond. At this time, we use Win7, Win8 built-in "emergency restart" technology to quickly restart the current system.
The specific operation is as follows:
First, Win8, Win8.1
1, in any interface of Win8 system, use the shortcut key Ctrl+Alt+Del combination key, open the following interface:
//In this interface, we can call the task manager, lock the computer or change the password.

2, hold down the current Ctrl key, and then select the power button in the lower right corner to open the emergency restart function

3, at this time, we can quickly restart the current Windows system. (Because the emergency restart does not support saving the current data, the user needs to save the document or program in advance.)
Second, Win7:
1, similar to Win8, use the shortcut key Ctrl+Alt+Del to open The following interface:

2, hold down the current Ctrl key, and then select the power button in the lower right corner

3, at this time, we can also enable the emergency restart function.
