For years, many Windows users have scratched their heads over the numbers displayed in Task Manager. Ever felt that the sum of individual process percentages never quite matched the total CPU usage shown? Well, Windows 11 is now rolling out a fix that should clear up this long-standing mystery—and it may fundamentally change how we interpret our system’s performance.
Task Manager is the go-to utility for monitoring system performance and resource usage. However, many have noticed an odd discrepancy: the individual usage percentages of each process never exactly add up to the total CPU percentage displayed. This phenomenon isn’t due to an inherent flaw in your hardware but results from different calculation methods being applied across the various pages of Task Manager.
Summary: The root of the confusion lay in Task Manager’s use of disparate formulas across its tabs, a design choice that made consistent performance assessment challenging.
In the latest Windows 11 build (26120.3360), Microsoft has addressed the core of the issue by standardizing the way Task Manager calculates CPU usage across all its tabs. Now, whether you’re checking the Processes, Performance, or Users page, you’ll see numbers that truly add up—matching both Microsoft’s internal calculations and what third-party tools have long reported.
This update isn’t merely a cosmetic overhaul; it’s an essential fix to how system performance is communicated to the user. By bringing all metrics in line with industry standards, Microsoft has made it easier for you to precisely interpret what’s happening under the hood of your PC.
Imagine you’re working on a project and suddenly notice that Task Manager reports nearly 100% CPU usage. In the past, a savvy user might have manually tallied the CPU percentages of individual processes, only to find that the numbers didn’t match up—potentially causing unnecessary alarm. Now, with the revised calculation methods, such anomalies are a thing of the past, leading to:
System administrators and IT professionals rely on consistent and clear data for performance tuning and troubleshooting. The re-alignment with third-party tools and industry standards means:
Breaking down the specifics, the discrepancy originated from different methods used in the calculation of CPU usage:

A: By aligning Task Manager’s CPU calculations with industry standards, third-party monitoring tools now have a consistent benchmark for assessing system performance, potentially improving their accuracy and reliability.
Summary: This FAQ section distills the key points regarding the CPU reporting fix, addressing common queries about the update and its broader implications.
With Microsoft’s update, Task Manager now mirrors the precision and reliability expected of modern system monitoring tools. This kind of transparency in performance metrics is crucial as we continue to push the boundaries of what our devices can do. Moreover, the option to revert to the legacy view shows that user preference remains a priority.
As Windows 11 continues to evolve, one can only expect more thoughtful updates like this that address user pain points and streamline the Windows experience. So next time you open Task Manager, take a closer look—might it just be the clearest view of your CPU’s performance you’ve ever seen?
Summary: Windows 11’s update not only resolves a longstanding inconsistency in CPU reporting but also sets a standard for transparency and precision. It’s another example of how continuous improvements in the operating system can lead to a smoother, more intuitive user experience.
What are your thoughts on the standardized CPU calculations? Have you noticed any other quirks in Task Manager that could use a tune-up? Share your experiences in the forum discussions—your insights could very well help shape the future updates of Windows 11.
Embrace the change, and let’s keep pushing for a more consistent and user-friendly computing environment.

The Long-Standing Confusion Behind CPU Metrics
A Historical Quirk in Task ManagerTask Manager is the go-to utility for monitoring system performance and resource usage. However, many have noticed an odd discrepancy: the individual usage percentages of each process never exactly add up to the total CPU percentage displayed. This phenomenon isn’t due to an inherent flaw in your hardware but results from different calculation methods being applied across the various pages of Task Manager.
- Processes Tab: Uses a unique formula that has historically led to seemingly inflated or deflated percentage sums.
- Performance and Users Tabs: Rely on an industry-standard formula that aligns with what third-party monitoring tools report.
Summary: The root of the confusion lay in Task Manager’s use of disparate formulas across its tabs, a design choice that made consistent performance assessment challenging.
What’s New? Standardization in Build 26120.3360
Aligning with Industry StandardsIn the latest Windows 11 build (26120.3360), Microsoft has addressed the core of the issue by standardizing the way Task Manager calculates CPU usage across all its tabs. Now, whether you’re checking the Processes, Performance, or Users page, you’ll see numbers that truly add up—matching both Microsoft’s internal calculations and what third-party tools have long reported.
This update isn’t merely a cosmetic overhaul; it’s an essential fix to how system performance is communicated to the user. By bringing all metrics in line with industry standards, Microsoft has made it easier for you to precisely interpret what’s happening under the hood of your PC.
- Uniform Reporting: The CPU workload displayed will now be consistent regardless of which tab you consult.
- Accurate Totals: The total CPU usage will now match the sum of individual process usages, eliminating the previously observed discrepancies.
- Better Integration: Aligning with established industry metrics means that tool developers and performance analysts can now count on Windows reporting being accurate and reliable.
Why It Matters
For the Everyday UserImagine you’re working on a project and suddenly notice that Task Manager reports nearly 100% CPU usage. In the past, a savvy user might have manually tallied the CPU percentages of individual processes, only to find that the numbers didn’t match up—potentially causing unnecessary alarm. Now, with the revised calculation methods, such anomalies are a thing of the past, leading to:
- Enhanced Usability: Easier interpretation of system performance means making informed decisions becomes much more straightforward.
- Peace of Mind: No more second-guessing whether your system is under undue stress due to a misreported metric.
System administrators and IT professionals rely on consistent and clear data for performance tuning and troubleshooting. The re-alignment with third-party tools and industry standards means:
- Streamlined Diagnostics: Troubleshooting becomes less cumbersome when all CPU usage data is presented uniformly.
- Better Resource Management: Recognizing true bottlenecks in system performance allows for more effective load balancing and resource allocation.
- Increased Confidence: When system metrics are consistent, deploying fixes and optimizations is less error-prone.
A Look Under the Hood: How Did This Happen?
The Technical ShiftBreaking down the specifics, the discrepancy originated from different methods used in the calculation of CPU usage:
- Processes Tab Formula: Previously, this page employed a unique method likely designed with a different internal focus, perhaps emphasizing responsiveness over strict arithmetic accuracy.
- Performance/Users Tabs Formula: These sections prioritized alignment with external standards, ensuring that the cumulative CPU usage reflected true system demand accurately.
A Step-by-Step Guide to Understanding the Change:
- Identify the Issue:
Notice how, in previous builds, the CPU usage was inconsistent across the tabs—sometimes showing near 100% overall, but with individual processes summing to far less. - The Fix in Build 26120.3360:
Microsoft modified the underlying algorithm to use a single, unified formula. Now, every tab draws from the same data set and calculation method. - Legacy Option for the Old Way:
Still not comfortable with the change? You can revert to the legacy CPU usage view. Simply right-click anywhere in Task Manager and select the legacy option from the context menu. This reveals the older CPU Utility column on the Details tab—a feature that remains available for those who prefer the traditional view. - Future Rollout:
The standardized calculation method is set to be included in upcoming releases as well—specifically in Windows 11 24H2 and version 23H2—ensuring that all users across various builds benefit from this fix.
