The Windows File Explorer accepts a USB device in its proper way, and displays the content as expected. After I finished whatever I was doing with the USB device (Memory stick) I attempt to disconnect the device by rightclicking on the device ID. This brings up the "reject". Clicking on this will then display the message that the device is busy by another program and cannot be rejected. There are no other programs running, and no matter what, I cannot reject the device. Obviously, I can just disconnect it anyway, but run the risk of loosing data. Is there a way to correct this erroneous behaviour?
