Microsoft has taken a significant step towards enhancing the accuracy of its Task Manager, addressing long-standing discrepancies in CPU utilization readings. The latest update for Windows 11 aims to align the Task Manager’s calculations with industry standards, moving away from the previous method that often yielded perplexing results. This change is expected to minimize the gap between Windows’ native tool and third-party applications like HWINFO and MSI Afterburner.
New calculation model: No more “pi times thumb”?
Historically, users have encountered a curious phenomenon where the Task Manager displayed CPU usage figures that diverged markedly from those reported by specialized software. This inconsistency stemmed from Microsoft’s unique calculation approach, which seemed to operate on a logic known only within the confines of Redmond. With the forthcoming update, the metrics presented in the “Processes,” “Performance,” and “User” sections will be standardized, mirroring the methodologies employed by external tools. While it remains uncertain whether this will prompt users to abandon HWINFO or similar applications, the native Windows solution is poised to become more practical for quick assessments of system load—provided that Microsoft executes the update with diligence.
Old values still optionally available
For those who have grown accustomed to the previous calculations, Microsoft has introduced a new column titled “CPU Utility” in the “Details” tab, which retains the old values. This decision raises questions about why a unified calculation method was not implemented from the outset, leaving some users to ponder the rationale behind the initial approach.
Rollout: When is the change coming?
The update is currently available in the Windows 11 Insider Preview Build 26120.3360 and is anticipated to be widely released with the upcoming 24H2 update. The timeline for this rollout will depend on whether Microsoft encounters any unforeseen bugs or decides to revise its plans. While the Task Manager may not undergo a radical transformation with the new CPU calculation, it is set to become a more reliable tool for users. Nevertheless, those in search of precise metrics are likely to continue relying on external programs, despite Microsoft’s assertions to the contrary.
