Shortcut hotkeys

I have written a batch file that I am going to use at startup to copy a shortcut to everyone’s desktop. The script works as designed. However, the hotkey that I would like to use for the shortcut will not. In this case I want to map the shortcut to the F7 key. It seems that the properties are not being copied with the shortcut. Is there any reason why this is not working. Below is the batch file:

c:
cd %userprofile%\desktop
copy \\safiles\chc$\general\IT_stuff\lock_computer.lnk c: /Y

Thanks in advance for any advice.
