its Version 2015 (417)
installed win 10 . beta I had same problem on another pc . I rolled back the win 10 & now that is fine so I can only assume thats it my problem here is this pc is not win pro 10 , but the home edition wont let you save or roll back for years its been solid on win 7 so im not happy that obviously win 10 & band in box 2015 have issues
