You need to be able to see that information specifically while hovering your cursor over a taskbar app? Seems oddly specific, my curiosity has me wondering why your cursor would need to sit in that specific location while referencing other information.
As someone else mentioned, you’ll need admin control of the system. I believe that, since Win11 25H2, there is no way to do this without third party software.
I’m pretty sure that DisplayFusion has that functionality.
WondHawk also has a plug-in to do that.
