This is the old "windows alert" nonsense. Everybody and their brother that touched the windows system thought the user would want a popup when their program did something. So the user experience was/is full of annoying popups, warnings, and information messages. Log onto a heavily-customized windows machine that hasn't been used in a month or two and it's like visiting Los Vegas. Good luck trying to get anything done.
Comcast. All kinds of other internet providers manage to communicate these things to their subscribers without this nonsense. Take a hint.
