What should I do if win10 can't be typed or typed very slowly?

After the level win10, I found that the typing reaction was very slow for a period of time after the boot. The computer will be stuck when I started the computer. This situation will last for several tens of seconds, and then it will be fine. After that, everything will be normal. It is very likely that there will be such a situation after the next boot. It is really mad at this thing. If you change other input methods, the virtual keyboard will become very strange, the letters will shrink to the upper left corner of the button, it is very ugly, and it is difficult to press.
