I have had momentary freezes where AC takes a 2-5 second period of unresponsiveness. While i had not thought of this as a Win 10 issue, I have not noticed it on the Win 7 machine (most of my machines are on 10).
Still it is annoying to have to wait for AC to 'wake up". Your description suggests that the freeze is permanent and that i have not seen. Might be worth chatting with tech support.
