#4. Lock USB port using BIOS
This way for those who know a little about computers is straightforward, but it is difficult for those who rarely use computers, so I do not recommend it.
First, you access the BIOS by pressing the DEL, F2, F8 … depending on the model you are using. (If you notice when booting into Windows, you will see a line displayed below the key to enter the BIOS interface).
You find the item USB Controller in the section
Advanced Settings and change
Disableto. To reopen, you need to do the opposite. Press F10 to save and restart the computer.
