It's a BUG after Win 1 1 last update, not your computer software. The reason for this BUG is the search on the taskbar, so you need to turn off the search. If there is a system push in the near future, it can be updated directly.

If you are in a hurry, you can follow my steps to close the search and solve the problem:

1. Click the right mouse button in the blank space at the bottom of the computer taskbar, and a taskbar setting will pop up, as shown below:

2. Enter the taskbar settings page (you can also enter it through Start Menu-Settings-Personalization on the left-taskbar settings), and you will see the search options. Some versions are displayed in the back, while others are hidden. As long as they are not displayed in the taskbar, the small transparent windows will disappear.

Win 1 1 has a transparent window in the middle. Solve the operation scheme.

If you have any other questions or better plans, you must send them out and learn and progress together ~

I like studying, and I like doing nothing!
