Hello Gerrard_2080,
You state the cursor stops responding and the only way to get it back is by pressing the windows key, is that correct? I will try to assist you with this issue.
When you are talking bout the cursor are you talking about the mouse cursor or the blinking cursor that appears when you start typing? Sorry some people refer to cursor being a couple different things just needing to confirm.
Please respond back at your earliest convenience.
Thanks
