How to block and block the use of external USB drives on your Windows 10 computer


 If you're connected to a network, there are some policies in Windows that prohibit such devices, but if you're using the device out of a network, there's a simpler trick to block ingesting external USB drives on your device.

To perform this task above, you will need to make a change to the system record. Therefore, it is recommended to create a recovery point or make a copy of your important files before continuing the procedure.

To perform this process, in addition to other profound modifications to the system, you must have an account with the powers of the manager. Check how to proceed:

Press the "Win + R" keys together to open the "Run" window and enter the command: Regedit. Click on "Enter";

 From the menu on the left side of the screen, go to this path: HKEY_LOCAL_MACHINE  SYSTEM  CurrentControlSet  Services  UsbStor;

 Click twice on "Start."


 Non-value to "4" and click on "OK";

Restart your computer.
After you restart your device, when you connect an external USB device or a hard drive, you won't be able to access it through File Explorer in Windows. It should be noted that such a change can also affect some cell phones, which sometimes define themselves as an external storage device.

To reset this setting, all you have to do is re-access the same record and change its value back to "3", not delete the original record under any circumstances because this will cause you problems within the system.
