You might have noticed that when you attach your USB drive to a computer at your school or office and computer doesn’t respond? It is because the administrator has disabled the USB ports and therefore, USB drives are not recognized.

Disabling access to USB ports is a great way to stop unauthorized users to transfer or steal data from your computer. Some might feel it is a cumbersome process, but do not worry as we have you totally covered. In this article, we have listed a few ways to enable/disable USB ports in Windows 7, 10.

1. Enable/Disable USB Drives By Making Changes In Registry

You can make changes in your Registry files to enable or disable the USB ports in Windows 7. Follow these steps:

  • Windows + R, type “Regedit” in the Search box to open Registry Editor.
  • Navigate to this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR.

  • In the right-hand panel, look for Start and right click on it.
  • A sub-menu will appear, choose Modify.
  • A small pop-up window will open, check if the value is 3.
  • If yes, then the port is already enabled. Change the value to 4 to disable the port.
  • Click OK to apply changes.

2. Uninstall/Reinstall USB Mass Storage Drivers

Another way to enable/disable the USB ports is, to install/uninstall the USB drivers. If you wish to use your USB device on your work computer or stop anyone from using your computer to transfer data, then follow these steps to uninstall USB drivers:

  • Click on the Universal Serial Bus Controllers.
  • You will get the list of USB ports.
  • Right Click on the USB port and uninstall the driver to disable the port.

Note: If you wish to install the USB driver in future, plug-in your USB drive and Windows will check for drivers. If not found, Windows will prompt you to install the driver.
