1. The concept is different: logout means that the system sends a request to clear the currently logged-in user, and then any user can log in to the system again. Restart is to restart the computer and reload the operating system in Windows which supports fast start, turn off the fast start function and turn it off completely, and then start the system by cold start.

2. The degree of memory release is different: logoff does not release memory, but restart will release all memory.

3. Different exit degrees: logout only exits the current user's operating environment, and all other related system settings remain unchanged. However, restarting will not only exit the session between the current user and the system, but also reinitialize the operating system.

4. Different functions: If there is a problem with the computer resource manager, reloading the resource manager after logout can solve some problems with the resource manager. However, the setting of starting the process after login in the system shell will play a role in the process of logging in after logout. ?

Extended data:

1. Difference between logout and switch:

Switching users means switching to another user without closing the currently logged-in user. The user may not close the running program, but the system will remain in the original state when he returns again. And logout is to save the settings and close the currently logged-in user.

2. Logout cannot replace restart, but can only clear the cache space and registry information of the current user.

3. Consequences of forced restart:

(1) Fast startup or restart will generate extremely high instantaneous induced voltage in the power supply circuit, that is, surge phenomenon will occur, which will damage the power supply and motherboard.

(2) The magnetic head and the magnetic head of a typical Winchester hard disk are separated and do not touch each other. However, at the moment of instant startup or restart, the magnetic head and the magnetic head will contact briefly, which will cause physical scratches. Similarly, the data in the hard disk cache will not be written to the disk, or the data written to the disk is wrong, resulting in soft tracks.

(3) If it's SSD, it's just data loss, nothing.
