How to turn off gvim's control of the input method

Question

After switching to win8, I found that gvim does not completely control the input method. It often opens the input method when it should not be opened. I can only find on the Internet how to turn on gvim's control of the input method (only open the input method in insert mode). It seems that it is turned off by default, but I have never turned it on and there is a problem. How to completely turn off gvim’s control of the input method?
