Disable USB Ports through BIOS

  1. Reboot the computer and watch the screen for instructions on which key to press for getting into the “What is BIOS“. On the screen you will see messages like “Press F8 to Enter BIOS”. This will vary from system to system; hence you need to find out the right key on your computer by reading the instructions on the screen. You may reboot the computer again, in case you missed the opportunity to read the instructions properly the first time around.
  2. Use the suggested Key to get into BIOS settings
  3. Next, Use the arrow key to select the “Advanced” tab “Onboard Devices” or “Integrated Peripherals” from the menu and Press “Enter.”
  4. Select “USB Controller” Press “+” or “-” or any other suggested key to change the setting to “Disabled.” In older operating systems, select “USB Legacy Support” “USB Keyboard Support” or similar option and change the setting to “Disabled.”
  5. Save the changes and exit BIOS by pressing the suggested key for your system  (mostly F10 Key).
  6. Reboot the computer and check the USB ports to make sure that they have been disabled.
