I do not want Photoshop to EVER ask me if I'd like to try a new feature, or anything else.

How do I turn off these "helpful suggestions" that make me want to throw my computer through a plate-glass window every time they pop up? How I turn them off FOREVER? 

I already have "Rich Tooltips" turned off, FYI. 

Seriously, whoever thinks distracting users while they're trying to work is good marketing should be fired.
