How can i tell which apps are hogging all of my IO ops, or stealing too much of memory using the Process Explorer?

Go to View > Select Columns... and open the Process Performance tab and add the I/O ops you wish to be displayed. Then open the Process Memory tab and make your selections there.

You just need Task Manager:

Go to Processes, menu entry View / Select Columns, and check either or all:

CPU Usage (gives percentage of total CPU in use)
Memory - Working Set (memory in use)
i/O Reads + I/O writes (counts total number of disk accesses done)

Task Manager isn't nearly as helpful as Process Explorer. Clearly this person is looking for help using PE instead of Task Manager – Zooks64 Mar 29 '10 at 19:52
@gadzooks64: Simple solutions are best. Many people overlook the power of Task Manager. No need to downvote a helpful comment. – harrymc Mar 29 '10 at 20:55
@harrymc I would have done the same thing if the OP had asked for help with Excel and someone replied with a solution suggesting they use Open Office. – Zooks64 Mar 29 '10 at 23:58
@gadzooks64: Not the same thing. Task Manager is standard in Windows and can be launched in more ways (ctrl-alt-del). It should be the preferred tool. – harrymc Mar 30 '10 at 6:36

You can click twice on the CPU column header to sort the process from highest to lowest based on CPU usage.

The same can be done with I/O columns once you have selected them as Molly suggested.
