STM32F030 Nucleo behaves as a CD/DVD-drive on USB connection!

Win10Pro 64-bit, ST-LINK_V2-1 driver, STMF030 Nucleo board with STMF030R8T6 64 pin, Win10 set to allow unsigned driver install.

I followed the installation instructions carefully, installed ST-LINK_V2_1 before connecting Nucleo board, did the firmware upgrade and all worked just fine. When the Nucleo board was connected a drive (H: Nucleo) showed up in windows explorer and programming *.bin files could be done by drag-and-drop to driver H:. SW4MS32-eclipse worked OK, debugging etc. After a while, without any obvious reason (possibly due to some Windows 10 update), on connection of the Nucleo board a H: drive without label shows up and Windows 10 asks me to "insert a disk".

I have tried to uninstall drivers, both from the Control panel and from the Device manager, re-boot and re-install ST-LINK_V2-1 driver but without success. So I cannot program the Nucleo board by drag-and-drop. It seems that despite my efforts I do not manage to uninstall the ST-LINK_V2-1 driver properly.

I also tried to install the mbed windows driver with the Nucleo board connected (mbedWinSerial_16466.exe) but the installer program fails saying that it cannot find any mbed enabled device, which the STM32F030 Nucleo board is supposed to be.

The work around I found was to upload *.bin files using OpenOCD.

Is there a solution to this issue? What can I do to obtain the original drag-and-drop behavior of the Nucleo board back?
