How to list all Privileges held by a Process?

Question

Using Process Explorer tool, we can see the privileges held by a running process. A running process might delete the privileges, and hence effective privileges held by the process would be less than what's allowed to the user/group.

If we open a process in ProcExp, and select 'Security' tab, we can see all privileges currently held by the process, and status of each privilege:

If we select any other process (Service) running under SYSTEM account, it would not have all the privileges (like SeTcbPrivilege) - the process itself might have deleted the process (using AdjustTokenPrivilege with SE_PRIVILEGE_REMOVED flag).

Which command can list the privileges held by a running process?

This answer is a bit late, but after fighting to with this myself, I thought it would be worth documenting the result:
Sysinternals accesschk.exe seems to do it.
It's sensitive to the order of the command line paramters, so it took a few experiments to get the expected result:
C:sysinternals>accesschk.exe -p -f 13488

This only works for the current user. I don't know how to specify a pid.
