Hi bailes. Here is the registry export. All you need now is a blank icon. If you don't have one, I can email it to you. Remember to always backup your registry before making any changes,
___________________________________________________________________________________
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Shell Icons]
"29"="C:\\Windows\\empty.ico"
____________________________________________________________________________________
Copy your empty.ico file to the C:\Windows folder
Then
Copy what is between the lines above
Paste it into Notepad
Save as ShortcutArrow.reg
Double click on the ShortcutArrow.reg file
Accept the 2 pop-ups
Reboot
(You may have to change the path, if your Windows folder is in a partition other than C.
And please backup your Registry before you make changes)
