Can you open a terminal/CMD window and try to launch Electrum from there using the -verbose flag, in order to
see what goes on, including error messages while it tries to connect?

Not even sure if that would work using windows, but worth a try.

If it does work and you get info from the attempt, post it here and maybe someone will
see the problem. If not, try the electrum IRC channel on freenode. The people there
are very friendly and helpful

As an afterthought, do you have all of the required python/dependencies installed on your W10 instance?
