Windows 10 window can't be closed?

The picture sometimes gets completely white when I'm in the browser and the window does not close and when I watch videos, the sound goes on and I can't do anything except switch it off. That's happened 3 times since yesterday

the laptop is new I've only had it for a few days

Do you know a solution how to close the window?

Thank you in advance

He does not care what I do

Sounds like a little bug, or virus. Do you have ne antivirus software on it? Delete your cookies and saved files in the edge.

Quit in Task Manager is not synonymous?

Thanks for the answer

Where can I download antivirus software and which exactly?

No, unfortunately not

Already tried with Taskkill?

Take an anti-virus program and let it go through.

Is pre-installed on Windows 10.

Windows Defender is enough. Several antivirus programs just get in the way

A PowerShell command to run as Admin: taskkill / f / in MicrosoftEdge.exe

Can also be saved as a batch, just right-click on the desktop, new, text document. Copy the text: taskkill / f / into MicrosoftEdge.exe and save it. The file extension must be changed from .txt to .bat, with yes confirm.
