So just to add my .02 cents, Adobe Reader displaying multiple instances of the open file in the taskbar happens on my Windows 11 machine (an Intel NUC 13) as well as my work PC (a Dell Latitude 5540, Win 11 as well). My work PC is pretty much locked down and I'm limited to making any changes to it.
Also, the scenario is more complex than just showing more than one instance of an open file... There's times when if a group of files are opened in separate tabs at the same time. and one of the files is closed, a remaining open file takes on the name of a file that was previously closed. I've double checked, and yes this does happen.
Attached is a file showing 2 pdf files open, with 2 references to one of the files in the task bar.
