Sometimes it is necessary to Block or Disable the USB to prevent your PC from viruses and Trojans especially when it is in a crowded area like in Office, School or College.
Here, I'm gonna show you a simple trick to Disable/Enable the USB drive in your PC without any third party software by simply making changes in the Windows registry.

• Open registry. Window Key+R > type regedit
• Navigate to the following registryHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR
• There in the right content pane search for REG_DWORD Start

• Double click on it and a new small pop box will appear.

• Change its value to 4 to Disable the USB
• Change its value to 3 to Enable the USB
• Sometimes a reboot will be required for the changes to take effect
