After updating DO to 12.26 (x64 version), the DO taskbar icons would appear for a brief moment on the starting of the program, and then get replaced by the usual windows explorer's icon (and I did not set DO to replace Windows' Explorer as the default file explorer.)
I have since uninstalled and reinstalled DO, updated my Windows 10, cleared the icon cache and rebooted my PC as one old post suggested. The taskbar icons would still revert to that of Windows Explorer. It doesn't matter whether I open on lister or multiple.
I have also checked the directory where the "change the icon" option in the program's properties window, to no use.
Please help me restore DO icons on the task bar because I also use Windows' File Explorer as well, and I don't want to get confused between the two apps running at the same time. Thanks.
