I am a huge fan of the improvements Microsoft has been making to PowerPoint over the last few years, it now outshines Keynote.
One thing though, is bothering me: after every recent update it is very hard to say “no” to the question whether Microsoft can record every single one of your clicks to make the program even better. You can simply accept or learn more.
On a Mac, I managed to make the window go away by repeatedly clicking on the red cross in the top left corner of the pop-up window, hopefully that registered as a “no”.
