I just bought an HP Pavilion computer two days ago. As soon as I opened an app on the computer, the most annoying box appeared in the right hand corner of the screen. It says that in order to switch between apps I must move my mouse into the corner of the screen and click, but the box never leaves and nothing ever happens. I researched and none of the solutions I found helped at all. Please help me get rid of this box!

Hi martha,

Do you mean the "Help Tips"?

If that is the issue, we can try the following group policy to disable it.(Run gpedit.msc)
Computer Configuration\ Administrative Templates\Windows Components\ Edge UI\ Disable help tips

A screenshot will help us to understand the issue more clearly, we can verify our account referring to the following link and then post a screenshot here if your symptom is different from my clarification.
