Hello Gus , So yes when I plugged the device it launched the windows explorer and i could browse the folder and add one of the makecode programs onto my device. However Windows still complained that it could not add the drivers for the Brainpad arcade.
Still i was able to use it to load programs but then I remembered that I also have a brain pad board and on that one you had to hold the boot and reset buttons together to get it into a different mode. So I did the same on this device but instead if tried the restet and menu button press them together those worked the computer made a sound and windows 7 began to to install the drivers for it.
Then i listed all the new USB devices and was able to see the new Device that the brainpad arcade added to my machine 
Gus , great job with this little board . congratulations to you and your awesome team. This is a great device and hopefully it can get a lot of attention from schools/ parents / Teachers and anyone interesting in learning to code 
cheers
