Is it possible to allow custom icons for your taskbar?

I intend to make discord have the icon of the MSN Messenger. I went to the directory to change the icon and everything. It shows up on the default windows taskbar, but not on retrobar.

As you can see on the pinned icons, the MSN icon is there (replacing the discord icon), but the discord icon beyond the MSN icon is still its default icon. I have had this "issue" for about a year now, and I just wanted to see if it was possible to fix that.

Update: I moved onto the newest version of firefox out of fear from the lack of functionality in 2025, and now the firefox icon refuses to change alongside the discord icon.

This happens because RetroBar uses the window icon, rather than the app icon, by design. The default Windows taskbar does this too, when set to not combine buttons.

I believe the only way to achieve what you're looking for is to patch the applications themselves to change their icon resources.

how exactly would I "patch the applications?"

You could use a tool like Resource Hacker if the icon resource is embedded and used within the Win32 application (otherwise you could use Windhawk's Resource Redirect mod with a dummy .exe file with the .ico resource modified), rather than an external resource or in a different format.

I tried to use resource hacker and it didn't work because every time I try to open this duplicated program, it just opens with this error. It also doesn't let me replace the original file in the firefox folder after I made changes to it. This is probably from some kind of countermeasure.

Thank you, the windhawk method worked for me after I pasted a few neurons in my chimp brain together
