it didnt happen to me because i have a very strongly customized nlite win7 but i can imagine the pain it causes you. i used 10 side by side from june '15 until early 2016. many people frown upon me when i say very critical things about windows 10 but i just cant help it and get confirmation from so many people with so many different annoying incidents etc. some of which even deny that windows 10 would cause their problem... thats how blinded people can get who joined the technology train not too long ago and ms provides the "feeling" of progress by writing 10.x in front of a kernel that is 95% windows 7/8 anyway. ok i gotta stop else i'll rant from sunset to sunrise again
