Microsoft just released Windows 11 Insider Preview Build 26120.3360 to the Dev and Beta Channels, with Windows Task Manager getting a minor but important upgrade. According to the Windows Blog, “Task Manager will now use the standard metrics to display CPU workload consistently across all pages and aligning with industry standards and third-party tools.” So, if you get this update, the Details tab of the Task Manager should now more accurately show you your PC’s current CPU utilization.
The function has previously been criticized for its inaccuracy because it based its computational charts on your computer’s base clock, not its actual or boost frequency. That means Task Manager was showing you a lower CPU utilization value versus what it actually used because it based its computation on your processor's slower base clock. So, if it used all of your processor's resources, you would often find that your CPU utilization went above 100% in the Details tab, adding the numbers manually.
