When using the task manager in Windows XP Pro, the amount of RAM that is listed as being used by the individual processes is not adding up to the total memory used (as listed by the total commit on the performance page).

The total sum of all the RAM being used the the processes: 195604 K

The amount in use as listed by performance page and the status bar: 280028 K

1) Why is this?

2) How do I reduce the amount of memory used?
