How Can a Process Break Away from a Job in Windows
Once a process is assigned to a job, it cannot break out. If that process creates a child process, the child process is by default is a part of parent’s process job. So far so good!
But, a process can run outside of the job in the following cases.
CreateProcess
Crafted
In a way that it includes CREATE_BREAKAWAY_FROM_JOB
. This will work, but only if job limit flag includes JOB_OBJECT_LIMIT_BREAKAWAY_OK
.
Job Object Forces It
The job object can include limit flag JOB_OBJECT_LIMIT_SILENT_BREAKAWAY_OK
. In this case, any new child process created by a process inside the job object is created outside this job.
