Check if someone secretly plugged USB into your computer

You may not know that we can actually use the Windows registry to detect whether a special USB device has been connected to your computer.

Importance of verifying USB device insertion

You may not believe it, but maybe one day we will really use this little trick. For example, your friend's mobile hard drive was seized by the police from you, but it was filled with children's island country action movies. At this time, it is very important to prove that this thing is not yours.

If we want to check whether a certain USB device has been plugged into our computer, we can operate the Windows registry. Because every time a device is connected to the USB port of your computer, the system will store the device serial number and corresponding information in the registry.
