AffinityMask

The affinity mask of the process.

BasePriority

The base priority level of the process.

ProcessId

The process ID.

ParentProcessId

The parent process ID.

Flags

Flags about the process. For more information, see PSS_PROCESS_FLAGS.

CreateTime

The time the process was created. For more information, see FILETIME.

ExitTime

If the process exited, the time of the exit. For more information, see FILETIME.

KernelTime

The amount of time the process spent executing in kernel-mode. For more information, see FILETIME.
