Sorry, but I don't know what to tell you about Task Manager.
However, there is a great alternative to Task Manager - SysInternals Process Explorer, available free from Microsoft TechNet. Many of us have replaced Task Manager with Process Explorer.
Download and unzip/extract. Nothing to install -
Process Explorer - Windows Sysinternals | Microsoft Docs
Simply RIGHT-click on
procexp.exe, select "Run as Administrator"
