Useful trick if u have something on your computer and you don’t want being copied by someone in a USB
Click on start–>Run type regedit
Expand to the following:
HKEY_LOCAL_MACHINE–>System–>CurrentControlSet001–>Control Add a new key and name it “StorageDevicePolicies”.
In the window on the right then create a new DWORD value and label it WriteProtect, give it a value of “1″ and users can no longer write to USB drives.
Changing the value to “0″ will allow to users to write again.
Go ahead protect your data :)
