HOW TO CHANGE THE APP ICONS IN THE WINDOWS TASKBAR
Windows is a weird ecosystem that has different types of apps, from legacy/Win32 to UWP/Modern apps. As a result, some apps allow us to change the icon of the apps pinned to the taskbar and some don't. To fix this problem, I've created a method that works regardless of what kind of app we want to pin to the taskbar. So please check out my HOW TO USE CUSTOM ICONS IN THE TASKBAR GUIDE. There are a few steps that involve a third-party app used to change the AppID of a custom shortcut, but if you follow along closely, you'll see that it works. I even have an example in the guide to make things easier. Enjoy!
