Preventing users from Writing to USB device(PEN DRIVE)

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.
