Disabling/Enabling USB Ports in Windows 7

It’s really very easy to enable and disable a USB port of your Laptop and desktop computer. Many companies disabled their employee’s laptop to prevent data threat. Also many schools, colleges and universities block the USB ports of their computer. So, here is the easy way to enable USB ports, access it and disable it back.

By tweaking the Windows Registry, you can disable the usb ports.

To Open Registry: Press windows +r & type regedit & press enter.


  1. Open the Registry Editor.

  2. In left pane of Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR.

  3. Right Click Start and Click Modify on right pane of Registry Editor.

  4. Do one of the following:

    a) To enable USB ports: change the value from 4 to 3

    b) To disable USB ports: change the Value from 3 to 4

  5. Reboot, and that’s it.

Note: Modifying the registry can cause serious problems that may require you to reinstall your operating system. I cannot guarantee that problems resulting from modifications to the registry can be solved.
