In the Win7 shutdown option, there are 7 ways to shut down, respectively
Switch user, log off (logout), lock (Lock), Restart (restart), Sleep (sleep), Hibernate (Hibernate), Shut down (off).
Here are the differences:
1.Switch user, Log off, Lock
WIN7 supports multi-user logins. This means that the user can log on as an administrator or as another user. such as: In my system there are currently two users logged in, one in active (active) state, one in the disconnected (disconnected) state.
Switch user is to let user a can use other account B to log in, user a use the state of the machine is retained, when the user re-switch plus a, you can inherit the last logged in the state to operate. For example, after using a login, open a notepad, Switch B login, and then switch back to a, then just opened the Notepad program is still in.
Log off is log off. After logging off, user A's current operation status is closed, and when the user uses a to log in again, it is equivalent to re-initializing A's login status. For example, after using a login, open a Notepad program, log off after the Notepad program is closed.
Lock is the equivalent of a normal lock screen. Lock screen is a good habit when users need to leave the notebook temporarily, in case the notebook is used by others.
2.Sleep, Hibernate
Hibernate hibernate. Save the state of the current operating system to the hard drive and disconnect all power from the notebook. On startup, read the last saved system state from the hard disk and restore it directly.
Sleep. Keep the state of the current operating system in memory and disconnect all other power supplies from the notebook, in addition to the memory supply. On startup, read the last saved system state from memory and restore it directly.
In terms of speed, sleep is faster than hibernate. It only takes 1 seconds for my machine to start using sleep, and Hibernate takes about 10 seconds. In terms of energy savings, sleep needs to power the memory, and hibernate shuts off all the power, saving electricity (but not much ^_^) than sleep.
3.Restart, Shut down
Restart restart, also known as hot start, shut down the operating system, do not power off, and then restart the operating system.
Shut down the machine. Shut down the operating system and power off.
