who is logging in my computer

Question

_{Thursday, August 22, 2019 8:58 PM}

This logon was not allowed in before but now has been accessing my computer a lot. Also, my event viewer is constantly saying that I am reading some credential vault stuff and I am only reading my event viewer. If this stuff is normal I would like someone to just shoot me a response here. 

An account was successfully logged on.

Hi MM,

According to your event log, there is not something special need to be noticed, normal phenomenon.

Only two account names appears in your event log, they are SYSTEM and DESKTOP-59MLST1$, if this DESKTOP-59MLST1$ is your own account, nothing needs worry.

Account Name:  DESKTOP-59MLST1$

Logon Type:  5

Description: Service logon—This is used for services and service accounts that log on to start a service. When a service starts, Windows first creates a logon session for the user account that is specified in the service configuration.

Security ID:  SYSTEM

Account Name:  SYSTEM

Description: SYSTEM account logging on, it’s normal.

Regards

What I find that only 2 users accessed system:

Account Name:  DESKTOP-59MLST1$

Account Name:  SYSTEM

System logon is absolutely normal. 

[Used only by the System account

eg.System startup.]
