I would like to customize my tray icons. Up until now I only had MusicBee permanently displayed in the tray and you can choose a custom icon for that because MusicBee has that functionality (it's awesome all around btw) but now I want to display other programs, too. I like a minimalist design, so I choose a fitting white music note as icon for MusicBee and I want to have all my icons in that style. So how do I change the icons? I would like to NOT use ResourceHacker or similar programs, since you have to do all the work again for every update.
Is this possible?

Thanks in advance
