How to make 4 desktops at the same time?

Question

Windows

Tell me how to divide the physical monitor into 4 virtual ones so that they can be seen at the same time and can be used without switching.
All the programs I've used basically see 4 desktops, but as soon as I click on them, they switch to 1 desktop and that's it. And I need to be able to work, seeing all 4 screens at once and manage them without switching to a separate one. At the same time, so that if there is a video broadcast on one of the monitors, it also worked.

Answer 1

Install multiple monitors or a pair of PCs, and share the mouse and keyboard using software:
