How to enable/disable usb ports


"Warning : Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. If a USB storage device is already installed on the computer"


set the Start value in the following registry key to 4:

2. In the Open box, type regedit, and then click OK. 
3. Locate, and then click the following registry key:


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor 


4. In the right pane, double-click Start. 
5. In the Value data box, type 4, click Hexadecimal (if it is not already 
selected), and then click OK. 
6. Quit Registry Editor.
