600: A process was assigned a primary token

On this page

This often happens when a service starts or a scheduled task starts under the authority of a different user. You will see events 528/540 and 552 as well as 680 or 672 earlier in the log.

The Assigning process fields identify the process that started the child (new) process. Process ID allows you to link this event to the corresponding event 592 (process start of the parent process) but there is little need since this event gives you the program name (image) and the user under which the process was running (primary user fields). See 528/540 for explanation of Logon ID.

New process information identifies the new child process that was started under the Target user name. You can use the new process ID to link back to the earlier 592 for the new child process ID but again there is little need to do this since you have the image name right here in this event.

The following parameters are tracked for both the assigning process and the new process.
