As I suspected, this change only affects the Processes (and presumably Details) tab in Task Manager, no changes to the Performance or Users tab.
The "windowslatest" site seems to get this partly backwards. The second screenshot in the article appears to be a standard handout from Microsoft, in that it is featured in virtually every article covering this topic. However, they seem to misunderstand the issue by stating:
That statement is incorrect. The "CPU Utility" option highlighted in the red square is the NEW column; current versions of Task Manager don't have this. This is the missing part of the puzzle, in that the Process performance counters were only time-based until now.As shown in the above screenshot, the “CPU Utility” column on the Details tab (which is off by default) shows the old CPU usage formula.
Continuing down the speculation rabbit-hole further: This is going to impact Rainmeter or at least Rainmeter skins.
These articles imply that there will be a new set of utility-based performance counters available in PerfMon, so any Rainmeter skin displaying "Top Process" info will need to be revised to reference these new counters if the skin author wants their skin to match Task Manager. The UsageMonitor measure with the CPU alias is hard-wired to reference "% Processor Time", so skin authors will need to revise their measures to not use the alias.
More importantly, Microsoft has indicated that the Process counter set is obsolete, and recommends everyone switch to using Process V2. If the assumed new utility counters are added to Process V2 and not to Process, there is a glitch in UsageMonitor that will require a code change, because the Process V2 counters cannot be parsed properly by the existing Rainmeter code.
