Hi all,
I just upgraded to Windows 10, and immediatly ran into the problem that is described in this thread about Windows 8:

After reading that thread I decided to unplug the other USB devices I had in the computer at the time (Garmin Watch, USB key, smart phone) and turn off the camera. I then turned on the camera and ran the EOS utility and it found my camera and worked correctly.
Clearly this problem is still not resolved, but that simple work-around gets me downloading my pictures again. There are a lot of other things people tried in the above thread, but I just unplugged the USB devices and was good to go.
