Ahh, well I'm not sure about the pop-up information bubble on your Clock.
You can click
Start > settings cog to open the
Windows Settings app, then select
System app and now in the
left pane select
Notifications & actions
If you
toggle off #1 in above image, the items like clock would be gone so the bubble could not appear.
If you
toggle off #2 in above image, that may reduce some of the other pop-ups you are seeing, or at least limit the number you see.
