How to block and prevent the use of external USB flash drives on your Windows 10 computer
When you lend your computer for use by someone else, it's always good to be careful with everything you can put in it. For example, a common source of viruses and unwanted files may come from external USB drives or hard drives, which easily connect to your computer via a USB port.
If you are connected to a network, some Windows policies prohibit such devices, but if you use the device outside a network, there is a simpler trick to block the use of external USB flash drives on your device.
To perform this task above, you will need to make a change to the system registry. Therefore, it is recommended that you create a restore point or make a copy of your important files before proceeding with the procedure.

To perform this operation, in addition to other profound modifications to the system, you must have an account with manager powers. Check how to proceed:
Press the "Win + R" keys together to open the "Run" window and enter the command: regedit. Press "Enter":
From the menu on the left side of the screen, navigate to this path: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ UsbStor;
Double-click "Start."
Change the value to "4" and click "OK";
Restart your computer.
After your device restarts, when you connect an external USB device or hard drive, you won't be able to access it through Windows File Explorer. It should be noted that such a change can also affect some cellular phones, which sometimes identify themselves as an external storage device.
To reset this setting, all you have to do is re-access the same registry and change its value back to "3", not delete the original record under any circumstances as this will cause problems within the system.
