I just used the register edit key commands and got the message "Cannot import C:\Users\Owner\Desktop\newfolder.reg: Not all data was successfully written to the registry. Some keys are open by the system or other processes." I rebooted and now there it is New_folder icon and it works!
The first time I attempted to edit the registry key I got the message "Cannot Import C:\Users\default.default-HP\Desktop\NewFolder.reg: The specified file is not registry script. You can only import binary registry files from within the registry editor." I didn't paste the part of the code that says Windows Registry Editor Version 5.00
