Does this require Administrator rights to see this granularity? In my office as a non-admin user, we have noticed that Task Manager seems really crippled.
You won't see other users processes, at least on my box however the detail is there for yours. Probably possible for it to be crippled by group policy.
In previous versions of Windows, the task manager menus could be toggled by double clicking an empty area in the window. You should also be able to select additional columns to display in the options. Note: I haven't used the win8 taskmgr.
