Resource Monitor
resmonA graphical, real-time view of CPU, memory, disk, and network usage broken down per-process — more detail than Task Manager, especially useful for spotting exactly which process is hammering the disk or network.
// EXAMPLE
Using the Disk tab to see exactly which process has a given file open when Explorer refuses to delete it ("file in use" errors).
// GOTCHA
Resource Monitor's per-process disk/network activity view is the fastest way to answer "what's using 100% disk" — a question Task Manager's default view often can't answer as precisely.
