Many a time I'm asked why an XP computer is running slow. No applications running. All systray apps killed except volume. CPU usage is ticking along at 5% or less. Commit charge is far less than physical memory, as is the peak. Swap file usage is low and constant. The disk activity light is on, solid.
Presumably some portion of WIndows has decided to take the disk for a good long run. But how do I find out why? Even if I can't do anything about it, it would be nice to have an explanation.
I've serached for disk activity monitors, and the closest I've come is sysintenals diskmon. But I don't see any way to trace diskmon's results back to a process or program.
Anyone got a way to do this?
