If all you want to do is hide the drives for all the users, you can easily do that with a LGPO. No KiX or admin rights for the users needed. You could also do it in HKLM just by hacking the reg.
Quote:

HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
NoDrives REG_DWORD 3C00000
where in binary it's: 11110000000000000000000000
each bit represents: ZYXWVUTSRQPONMLKJIHGFEDCBA
