Windows USB Blocker is a small tool with the help of which we can easily block/unblock in Windows access to various types of USB data carriers - USB flash drives, external hard drives, etc. These USB storage media are one of the main sources of the spread of malware without the user's knowledge. Most often it is enough for an infected USB stick to be connected to the computer, and automatically harmful components will be installed on it.

The most effective solution to this problem when the user is absent is to turn off the USB ports in the system. This is where Windows USB Blocker comes in and locks USB ports in the operating environment with just one mouse click. If necessary, USB support can be reactivated at any time.
