Ways to hide open windows?

I have a project at school right now where we're going to help the teachers find out if a student has used their laptop to play, so I need a few ways to hide open windows and ways the teachers can can discover.

You actually want to have a list of tasks. A window can also be temporarily closed.

Unfortunately, teachers can see what is displayed on your screen, so it doesn't help if you make the window invisible

I'm interested in how to hide open games, because you first try to keep the game state, if you close it with Alt + F4 everything is often gone

I'm actually talking about a school project, the teachers can't see it with us because we have laptops that we bought through school

Strangely, the Teamviewer will be installed on all of them…

No, we downloaded all programs ourselves and only programs such as Word and Co are installed

In addition, many have their own laptops and there's certainly no software from the school installed on them, so that the screen is visible

There are programs such as: Spector or eBlaster that can monitor which programs have been used for how long or you can simply check which games are installed

Games may be installed, but they may not be used in the classroom, there's an option from Windows to look up what was used because on the private laptops, nothing may be installed by the teachers.

Unfortunately not from Windows

Hm, thanks anyway

I use Dexpot. With one click, I have other windows.
