How to limit Drive Letters Windows assigns to new removable USB drives
Currently Windows (all of the versions) assigns the first available letter to the next removable media you insert into your USB drive. Is there a way to go around this to make Windows assign only letters that are in the interval you want (for example S - Z)?
USBDLM is a Windows service that gives control over Windows' drive letter assignment for USB drives. Running as service makes it independent of the logged on user's privileges, so there is no need to give the users the privilege to change drive letters. It automatically solves conflicts between USB drives and network or subst drives of the currently logged on user. Furthermore you can define new default letters for USB drives and much more. It works on Windows XP to Windows 10.
