Why is my Windows 11 Mail app not working? So now I'm not sure whether the Dropbox promo popup is being caused by the Win10 that came installed on the HP PC or maybe from one of the 3 HP programs remaining.Home › Windows 11 › How To › Fix Windows 11’s Mail app The Dropbox promotion popup happened after that. In Program & Features, I had previously removed everything not normal except for three HP programs.

Nor is there a Dropbox promo listed in Program & Features. But it is not listed in Win10's Program & Features so it is not pre-installed on my friend's HP PC. Googling, I see that Dropbox may come pre-installed on some HP and Acer PCs. But that will be too much for my friend to handle.

I had to get rid of the popup by opening up Task Manager and doing an 'End Task' for Dropbox. While using the PC, a Dropbox promotion popped up and the popup did not have any way to close it except to click the 'OK' button which I guess is 'OK to install Dropbox'.
