Bug Report Task Manager

This bug was introduced in Windows 1809 (Redstone 5 Oct 2018 Update). The Task Manager reports total CPU use correctly, as is confirmed by the Resource Monitor. The Resource Monitor reports CPU usage by individual apps correctly but the Task Manager does not. Instead the Task Manager reports a fictitiously low figure, less than 10% of the actual usage for individual apps, even though total CPU use is reported correctly. This bug can be reproduced by doing a CPU-intensive task such as video encoding (H264 or H265), and in multiple instances if need be.
Hello, A pleasure to help you.

I must tell you that the problem that occurs after the update is known and the Microsoft team is in the process of investigation, since several users have reported this incident.

"We have paused the implementation of the Windows Update October 10, 2018 (version 1809) for all users while investigating isolated user reports that are missing some files after the update.
Microsoft employs a gradual implementation scheme, and not all Windows 10 users have received their last six-month update of the operating system. "

They suggested that you follow the Workaround steps that Microsoft requests to know about your incident described in the previous article.
 
Please let me know if the information was useful or if you need to continue with my support.

Here's a screenshot, in case it helps. Note that it is sorted as per CPU usage, still shows only 1% use in individual apps

I got this problem, and, at least on my PC, it is solved by KB4467708 (although it is not explicitly mentioned by Microsoft in https://support.microsoft.com/en-us/help/4467708 ).
