I’m not sure WHY this is the case, but the Diablo III icons that Blizzard installs by default, to desktop and start menu, are really weird in Windows 7.
If you use one of them to “pin to taskbar” like you would (nearly) any other application, you can’t right-click on them, for example to remove them (they also don’t have ANY jump list). But you can move it around the taskbar. It won’t even show up in the AppData folder C:\Users\USERNAME\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar with all the others which is even weirder.
The solution is: let Windows do the work for you.
- Find the original shortcut you pinned to the taskbar. (Skip to 3 if you already deleted it, like with the desktop icon.)
- Send it to the recycle bin.
- Click on the taskbar icon. Prompt will pop up asking if you want to delete the shortcut. Do so.
- Restore the original shortcut back to wherever it was if you want.
Okay, so now that the crazy witchcraft shortcut is gone, you can make a new one. Head over to your D3 install directory (C:\Program Files (x86)\Diablo III), right-click on the Diablo III Launcher, create a shortcut, and then drag that shortcut to the taskbar. You can delete the one in the install directory if you like.
Now you have a perfectly normal taskbar icon that launches the D3 launcher. Yay.
