Send as Adobe Document Cloud Link in Hotmail Account

I recently downloaded the Free 7 day Trial but decided it wasn't of much use to me and cancelled.  When I downloaded the trial I was asked if I wanted to use it as a default & I answered yes, not realising that it would change all my saved documents to adobe.  Now I have cancelled the free trial I can not longer open those documents without being asked (again) if I want to pay for monthly Adobe subscriptions (which I don't).  On downloading the free trial Adobe have installed this "Send as Adobe Document Cloud Link - yes / no" but sometimes won't let me check No.  I have seen a post where somebody wanted to "uninstall" this feature but could not really follow twhat needed to be done.  I am not a very advance user (of IT) and it was all rather over my head.  Can someone tell me step by step (in Laymans Terms) how I can remove this feature from my Hotmail account?
