But with its redesign first introduced in Windows 8, Task Manager’s Processes and Performance tabs now rely on different metrics and present numbers that are misleading and that without additional context are completely meaningless. Task Manager’s changes were intended to accommodate advances in chip technology. It is relatively straightforward to determine a processor’s utilization: how much time during a given interval that it spends busy vs. idle (*). Back when CPUs always used to operate at a fixed frequency, simple arithmetic told you how much work a CPU had per
