There is a window advertisement in the upper right corner of the computer in the Internet cafe when I turn it on. I don’t know how to turn it off.

1. Directly find the close button of the ad and turn it off

2. Start the task manager and see the corresponding program running in the background to end the task

3. Ask the Internet cafe staff if it is a window that can be closed. Some Internet cafes will deliberately set some things that cannot be closed
