Windows are one of those things that are common in Windows 10. Right? Well, to a large extent that is of course a truth like a cow. But you can best adjust the standard behavior!
Most users of Windows 10 do not think very much about the behavior of windows. You can drag them larger or smaller or maximize and minimize them. Some people master the trick of quickly aligning windows next to each other. That can come in handy if you have several windows open at the same time and you want to see them neatly arranged. Just slide a window over the left or right edge of your screen and see what happens! Now you may find the behavior of automatically distributing windows in Windows annoying. Somewhere understandable, because if you accidentally drag a window too far to the left or right edge of the screen, you immediately switch to the “divide mode”. To prevent automatic splitting, first start the Settings app. Then click System and then in the left column Multitasking. Then place the switch below in the panel on the right Align windows from. From now on, Windows no longer responds to “scrolling through the left or right edge” of windows.
In principle you can choose the option that comes with alignment (or: the options that are available when enabled Align windows) best left as they are. The only thing that might be useful is to disable the option If the size of a pinned window is changed, the size of any adjacent windows is also changed. By turning that off, you are no longer stuck with the split screen format. In other words: once you have placed windows next to each other, you can drag one of the windows smaller through the dividing line, but that irrevocably results in the other panel becoming wider. If you don’t want that, turn the switch off at the last option.
