Windows 11 24H2’s Task Manager new CPU usage formula rolls out to everyone

stapp · May 27, 2025

With Windows 11 24H2 KB5058411 (May 2025 Update), the Processes tab formula for CPU usage now matches the Performance and Users tabs in Task Manager. Previously, the Processes tab maintained a separate formula, which is why CPU usage didn’t match across all tabs, but it has been updated to match the industry standards by default.

In Windows 11 24H2 KB5058411, Windows Latest noticed that Task Manager now applies the same formula for calculating CPU usage across all three tabs:

CPU % = (Δ Process CPU Time) ÷ (Δ Elapsed Time × Logical Processors)

Just so you know how to work it out

Also up and coming..
Windows 11 will throttle your CPU when you’re away to boost battery life.

Windows 11 is getting a new feature that might help extend the battery life of your laptop or 2-in-1. No, we’re not talking about yet another AI gimmick. Instead, it looks like Microsoft is testing a new “User Interaction-Aware CPU Power Management,” which applies to the whole operating system.
I noticed a reference to “User Interaction-Aware CPU Power Management” in a Microsoft blog post while I was looking for other things. Based on the details we’ve, it looks like the feature tries to reduce CPU usage when you’re not actively using your PC.
