Stop the Acrobat Welcome from Always Opening
Although no adobe products are set as startup items and the Adobe Acrobat Pro DC general settings have the option to show a start screen as OFF... with each newstart of the computer, the Acrobat Start screen opens.... and every time has to be manually closed.
This is a bug (although probably intended by Adobe) and needs to be fixed to remove this major annoyance.
The effect is that Adobe is trying to be an annoying microsoft application by making its own rules to decide what I want... but in reality is frustrating.

Sorry to hear that you had trouble.
Would advise you to move to the latest DC version, in you still see the issue try the setting mentioned here-
In this wiki use the key bToggleFTE as mentioned.
Let me know if you need any further information.
