In some business environments, it’s usually a good idea to lock down the usage of external USB storage devices and memory sticks to prevent users from accidentally introducing a virus onto the network or copying data off the network.
You can manually modify the registry to lock down the USB storage devices by changing the following Windows XP registry value:
- HKLM\SYSTEM\CurrentControlSet\Services\USBSTOR
- Change the Start REG_DWORD value from a decimal 3 to a decimal 4
