7 different shutdown modes in Windows 7

There are 7 shutdown methods in the win7 shutdown options, respectively

 

Switch user, log off, lock, restart, sleep, hibernate, and shut down ).

The following describes their differences:

1. Switch user, log off, lock

Windows 7 supports multi-user logon. In other words, users can log on as administrators or other users at the same time. For example, in my system, two users are currently logged on, one is active and the other is disconnected.

The switch user enables user a to log on using another account B. User A's machine status is retained. When the user switches over and adds a, the user can inherit the status of the Last login for operations. For example, after using a to log on, open a notepad, switch B to log on, and switch back to A. At this time, the opened Notepad program is still in progress.

Log off means logging out. After cancellation, user a's current operation status is disabled. When user a logs on again, it is equivalent to re-initializing the login status of user. For example, after logging in with a, open a Notepad program. After logging out, the Notepad program is closed.

Lock is equivalent to a normal lock screen. When a user needs to temporarily leave the notebook, it is a good habit to lock the screen to prevent the notebook from being used by others.

2. Sleep, Hibernate

Hibernate sleep. Save the status of the current operating system to the hard disk, and then cut off all the power of the notebook. At startup, read the last saved system status from the hard disk and resume use.

Sleep. Saves the status of the current operating system in the memory. In addition to the memory power supply, all other power sources of the notebook are cut off. At startup, read the last saved system status from the memory and resume use.

In terms of speed, sleep is faster than hibernate. It takes only one second for my machine to start with sleep and about 10 seconds for hibernate. In terms of energy saving, sleep needs to provide power for the memory, while Hibernate is to cut off all power supplies, saving power than sleep (but it does not save much ).

3. Restart, shut down

Restart restart, also called Hot Start, shut down the operating system, do not turn off the power, and then restart the operating system.

Shut down shut down. Turn off the operating system and power off.
