Registry Hack to Disable Writing to USB DrivesA common security concern at 
organizations is allowing users to plug in a usb flash drive, because they 
could so easily copy corporate data.

Since Windows XP SP2, you can disable writing to USB devices altogether 
using a simple registry hack. Here it is:

  [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]
  "WriteProtect"=dword:00000001

You can also just download one of the following registry tweaks to enable or 
disable writing to USB drives.

Enable USB Write

Disable USB Write

Once you use the registry hack, you will have to reboot for the changes to 
take effect. One should also note that if you are using this trick, you 
should make sure that the users are not administrators on the computer, 
because they could easily change this setting back.

This works on Windows Vista as well. Here's the window you'll get when you 
try and write to a USB drive:
