Remarks
If you specify the JOB_OBJECT_UILIMIT_HANDLES flag, when a process associated with the job broadcasts messages, they are only sent to top-level windows owned by processes associated with the same job. In addition, hooks can be installed only on threads belonging to processes associated with the job.
To grant access to a User handle to a job that has a user-interface restriction, use the UserHandleGrantAccess function.
