Very Nice find.
I was playing around with it.. I was able to change the icon of the zune. When you go start all program zune and click the arrow it show up, plus when i pin it to the start menu.
Now to do it.
Click Open then find where Zune.exe is located on your hard drive. my is C:\Program Files\Zune\Zune.exe .
Click Open,
Then click Icon Group then IDI_APP the 1033.
Go up to Action Button click it then Click Replace Icon
Then click open file with new icon.. has to be a .exe, .dll, .res, ico.
Whatever you choose click it then click open, then click replace
As you see I used command prompt, I also used the registry icon.
Then Click File Save As, and highlight Zune.exe, or Zune.
Ask if you want to overwrite click Yes.
We are almost done.
Now lets go into the Zune Folder by using My computer. Onec again mine is C:\Program Files\Zune.. double click the folder and click any where to refresh the folder.
Now you should see the icon u replace it with. Go over it Right Click it and select pin to start Menu. Also i had to go into the zune folder on start all programs delete the one that is in ther and drag it from the start menu.
