If you have any kind of problem with windows 10 PLEASE contact them here: https://partner.support.services.microsoft.com/en-gb/contact/chat/19/?mode=live
you can talk to a REAL person and if you are persistent enough they will tell the developers themselves, we need as many people as possible to complain directly at microsoft to make a real difference and fix the problems with 10.
Edit: That's the British link above because I'm in the UK, here's the US link: https://partner.support.services.microsoft.com/en-us/contact/chat/19/?mode=live
