Since a lot of us use the Acer W3 for our robots, I thought I should post this:
If you check compatibility from the Windows 10 reservation tool, it will tell you there is not a compatible driver for the video, but I did some research and the video doesn't need a driver. You can download the media creation tool from here: http://www.microsoft.com/en-us/software-download/windows10 and when you run it, select "upgrade this machine" and it will upgrade just fine. (you might need the driver if you connect an external monitor with the Micro HDMI cable. I haven't tried and have no need to).
Also, as per this discussion: http://www.ez-robot.com/Community/Forum/posts.aspx?threadId=8073&page=2 Windows 10 has far better support of Bluetooth headsets than Windows 8.1 did.
