..

• Open the Windows Registry and open the following keys

HKEY_LOCAL_MACHINE\SYSTEM\

CurrentControlSet\Services\UsbStor

• Now in the Right pane, double-click Start and type 4 in the Value data box (Hexadecimal) and quite the registry editor.

• To enable the USB storage devices, change the Start value back to 3.

Another Method:

• Go to start -> Run ->regedit hit Enter .....

• Open the Windows Registry and open the following keys.

HKEY_LOCAL_MACHINE\SYSTEM\

CurrentControlSet\Control\StorageDevicePolicies

• Now add a new DWORD called WriteProtect and put the value as 0 to disable write privileges to the USB port.

• To reverse the step, either delete the WriteProtect REG_DWORD or toggle the value to 1 which will enable the port.
