Windows 10: Task manager total cpu incorrectly shows a high value

I've just upgraded to the newly released Windows 10 Home 1809 and notice in task manager that the total at the top of the CPU column is always much higher than the actual sum of the detail.


For example, at the moment total CPU is over 60% but there is just one task with usage (slightly) over 2% and all the rest below 1%.


Any ideas?

:)

To further troubleshoot the issue, we suggest checking the Task Manager again to see what are the
applications that have high CPU usage. To do this, follow the same steps you did from the previous reply:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

However, based on your response above, it seems that you may need to create a new user account again and just install your apps manually instead of copying them as your
previous user account might be corrupted.

Once your done with the steps, please let us know how it goes.
