Using this function, prevent the write to USB devices.
This function is only available if you are using Windows XP SP2, I’m unsure of the other Windows OSes.
Action is immediate without need to reboot or log off the system.
Risk yourself but you can always write to me for further queries.
Simply, go to registry editor it regedit in Run Dialog Box,
Point to or search HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
Create or check for New Dword, create or edit string WriteProtect and assign the value 1.
Close the registry and there you’re.
Got seen the USB DEVICES blocked or unrecognized by the system.
