After years of complaints about Windows Task Manager displaying CPU utilization incorrectly, a fix is finally on its way

With the latest Windows Release Preview, Microsoft is fixing a problem that has persisted for years: Its Task Manager CPU usage stats didn't make a lot of sense.

This change was originally announced in the Windows 11 Insider Preview Build at the end of February and has now finally launched onto the Release Preview channel.

Effectively, as this community thread from back in 2020 shows, Task Manager made its CPU calculations based on the base clock of a CPU, as opposed to its effective or 'real' clock.
