I'm sure a spinning disk would make it worse, but I do have an SSD (admittedly, a 2013 model and not the fastest). To answer the grandparent, build 15063 and I'm using the laptop keyboard.
I tried a few times and I can consistently make Windows miss at least the first keypress if I haven't opened the Start menu in a few minutes.
